This diploma´s thesis aims to model the hydraulic model of the Brno – Ivanovice water supply system. The software MIKE URBAN for model hydraulic model of water supply system was used. It was performed a simulation of the various states of loading. The water supply system was assessment of pressure ratios. The outcome of this work is calibrated hydraulic model of water supply system. The appendix consists also of drawings, which represented pressure ratios, which are situated on water supply system. On the fourth drawing is described transparent situation of Brno-Ivanovice water supply system.

The setup of a 1D – Hydraulic Model based on available data shall support the development of the distributed catchment model for mountainous catchments in the Batinah Region (Sultanate of Oman). The main task of this study project is Model setup for Al-Awabi watershed area: This comprises calculation of sub watersheds and channel network using ArcGIS for a selected watershed based on ASTER-DEM (27X27m); derivation of cross-section at decisive stations of the longitudinal sections based on ASTER-DEM (27x27m), satellite images and Russian topographic maps; and Setup of 1D-hydraulic model i.e. MIKE 11 HD. This study is conducted at the mountainous catchment part of Batinah Region of the Sultanate of Oman called Al-Awabi watershed which is about 260km2 in area; four sub-watersheds in the Al-Awabi watershed are selected for analyses with channel lengths of 11, 6, 4 and 7 km. Channel cross-sections are the main input to the 1D-Hydraulic Model set up of the Al-Awabi watershed. As field measurements of the Wadi channel cross-sections are labor intensive and expensive activities, availability of measured channel cross-sections is barely found in this study area region of Batinah, Oman; thereby making it difficult to set up the 1D-Hydraulic model i.e. MIKE 11 HD. Hence, a methodology for extracting the channel cross-sections from ASTER DEM (27mX27m) and other relevant topographic maps are used in this study area. Also, observed Wadi-runoff events within the watershed were extracted so as to assess the Al-Awabi watershed. Furthermore, it had been observed that the MIKE 11 system results can provide helpful information about Flood Risk Management and should be useful in assigning priority for the development of risk area map for flood control plans and countermeasures for the settlements and inhabitants located right along the main channel within the watershed, and for that of Awabi town located just downstream of the Al-Awabi watershed outlet. But, an improved and well developed rainfall forecasting system could be worthwhile and more feasible for the flash flood routing analysis in arid areas such as this study area; hence MIKE NAM is recommendable instead of running MIKE 11 which requires discharge and/or water level as a basis for simulation of the flash flood. The performance of the calibrated 1D-Hydraulic Model i.e. MIKE 11 HD was assessed and validated to simulate the flash flood at different cross-sections of the channel reaches within the Al-Awabi watershed area. And from this study, although there are a major gap and problems in data as well as in the prevailing topography, slope and other HD parameters, it was concluded that the 1D-Hydraulic Model set up work, MIKE 11, can be applied for the Al-Awabi watershed.:Executive Summary 1 Zusammenfassung 2 1 Introduction 4 1.1 Research Objectives 4 1.2 Overview of Relevant Literature Review 4 1.2.1 Flood Routing 4 1.2.2 MIKE 11 Hydrodynamic Model 5 2 Study Area and data 5 2.1 Study area 5 2.1.1 Target Watershed Area 6 2.2 Data 8 3 Model Set up of Al-Awabi Watershed 12 3.1 Model Research Methodology 12 3.2 Discussion of Findings 12 3.2.1 Channel Geometry Realization from Google Earth and Russian Map 14 3.2.2 MIKE 11 Hydro Dynamic Modules 15 4 Discussion 17 Bibliography 19 List of Figures 20 List of Tables 20 Acknowledgments 21 / Die Entwicklung eines Einzugsgebietsmodels für die Batinah Region im Sultanate Oman soll durch den Aufbau eines eindimensionalen hydraulischen Models, basierend auf vor Ort verfügbaren Daten, unterstützt werden. Dieser Beleg fokussiert die Einrichtung eines hydraulischen Models für das Al-Awabi Einzugsgebiet. Dies umfasste zunächst die Ableitung von Teileinzugsgebieten und des Wassernetzes mithilfe von ArcGIS für die Untersuchungsregion. Grundlage bildete ein ASTER-DEM (27x27m). Desweiteren wurden Querprofile entlang des Gewässerlaufes an zuvor definierten Punkten, basierend auf ASTER-Daten, Satellitenbilder und Russischen Geländekarten, abgeleitet. Darauf folgte abschließend der Aufbau eines eindimensionalen hydraulischen Models mit MIKE 11 HD. Betrachtungsgegenstand war das bergige Einzugsgebiet Al-Awabi als Teil der Batinah Region im Sultanat Oman. Das Untersuchungsgebiet hat eine Ausdehnung von etwa 260km². Für genauere Analyse wurden vier Teileinzugsgebiete ausgewählt mit Gerinnelängen von jeweils 11, 6, 4 und 7km. Querschnittsprofile innerhalb dieser Einzugsgebiete bildeten die Informationsquelle für das Model. Da aus zeit- und arbeitstechnischen Gründen Feldmessungen im Untersuchungsgebiet zu den Profilen nicht möglich waren und auch nicht auf bereits vorhandene Messungen zurück gegriffen werden konnte, war ein Modelaufbau nicht ohne weiteres möglich. Daher wurden die benötigten Fließquerschnitten aus dem ASTER-DEM und anderen relevanten topographischen Karten abgeleitet. Ferner wurden für den Modelaufbau nur markante Durchflussereignisse verwendet, die am Pegel Al-Awabi vergezeichnet wurden. Es ist darauf hinzuweisen, dass die mit MIKE 11 erzielten Ergebnisse beim Aufbau eines Hochwasserrisikomanagements Verwendung finden können. Besonders für die Ableitung von Gefahrenkarten sind diese Informationen wichtig, um beispielsweise Prioritäten in Notfallplänen festzulegen und Maßnahmenkataloge für die lokale Bevölkerung zu entwickeln. Potentiale sind in Bezug auf den Aufbau eines Vorhersagesystems zu sehen, dass geeignet für die Analyse von Sturzflut in ariden Regionen, ähnlich dem Untersuchungsgebiet, genutzt werden könnte. MIKE NAM ist geeigneter als MIKE 11 für Analysen dieser Art, benötigt aber genauere Informationen zu Durchfluss bzw. Wasserstand. Das Model wurde kalibriert und validiert um Stutzfluten an verschiedenen Querschnitten des Flussbettes zu simulieren. Obwohl große Lücken in der Datengrundlage vorlagen und Probleme bei der Definition von hydraulischen Parametern auftraten, war es möglich ein eindimensionales hydraulisches Model für das Al-Awabi Einzugsgebiet aufzubauen.:Executive Summary 1 Zusammenfassung 2 1 Introduction 4 1.1 Research Objectives 4 1.2 Overview of Relevant Literature Review 4 1.2.1 Flood Routing 4 1.2.2 MIKE 11 Hydrodynamic Model 5 2 Study Area and data 5 2.1 Study area 5 2.1.1 Target Watershed Area 6 2.2 Data 8 3 Model Set up of Al-Awabi Watershed 12 3.1 Model Research Methodology 12 3.2 Discussion of Findings 12 3.2.1 Channel Geometry Realization from Google Earth and Russian Map 14 3.2.2 MIKE 11 Hydro Dynamic Modules 15 4 Discussion 17 Bibliography 19 List of Figures 20 List of Tables 20 Acknowledgments 21

At Epiroc’s drill rigs a safe system is installed to make sure the vehicle is driven in a safe manner. In the development both machine tests and hardware-in-the-loop (HIL) tests have been performed but when changes are made the firmware in the safe modules has to be updated. To speed up the process a digital twin would be beneficial. This enables testing of parameters and formulation of criteria detecting faults. The purpose of the work is to develop a digital twin for steering and braking safe functions and evaluate the performance using data from machines as well as data from a HIL-rig. Also, the impact of the hydraulic model used in the HIL-rig is investigated. When the model is built two test cases are used to investigate how well the model replicates the behaviour of the real system and how sensitive it is to what input data is used. The biggest difference in the data is the sampling time, machine logs have 80 ms interval while logs from the rig are logged every 5 ms. It is discovered that some of the fault detection functions work very well no matter what data is used while others must have the better resolution to be trusted. The complexity of the hydraulic model used impacts the pressures but seem to have little effect on which fault codes are activated. With this the main purpose is partly achieved and further investigation is needed before the model can be used for all fault codes.

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding. A flooding event is evaluated by how high the water level will reach and at which time the top of the hydrograph is accruing. There is a need for a tool for short time prediction of flooding events in the Nedre Dalälven region. In this study a hydraulic model in the software HEC-RAS has been used, here called HEC-RAS NEDA. The hydraulic model came up with good results when predicting water surface levels. The validation process made from figures of a period with large amplitude in water levels showed that the modelled water level was within ± 0,05 m from the observed water stands. It is a stable model that can handle 100-year flows with quick changes in the flow. The correspondence is good concerning the water levels and it functions well when studying the top of the hydrograph. HEC-RAS NEDA is an accurate and easy to manage tool for prediction of flooding in the lake of Bysjön, Österviken and Färnebofjärden. Modelled results have been compared with the model made by Swedish meteorological and hydrological institute on the request of Räddningsverket. The results from the two models shows large discrepancies, probably because of low accuracy data entered into the model from Räddningsverket. Räddningsverket has used the Geographical Sweden Data height data bank´and I used the height data from a laser scanned digital terrain model. Area studies have also been made according to how the area of the water surface changes with the water stand. These studies show that during the flood in year 2000, 55 km2 was flooded based on laserscanning in Färnebofjärden. / Mygg förekommer i extremt stora antal i området kring nedre delen av Dalälven. År 2000 var myggplågan särskilt stor vilket medförde att projekt Biologisk Myggkontroll bildades. Myggbekämpning har bedrivits i Nedre Dalälven sedan 2001 med ett biologiskt bekämpningsmedel, Bacillus thuringiensis ssp israelensis (BTI). Områdets myggfauna domineras av så kallade översvämningsmygg, en grupp stickmyggor som är mycket aggressiva och bildar nya generationer efter varje enskild översvämning under sommaren. För en effektiv bekämpning av mygglarverna krävs att man vet översvämningens omfattning och lokalisering. En översvämning bedöms med avseende på hur högt vattenståndet når samt vid vilken tidpunkt hydrografens toppvärde inträffar. Det finns ett behov av ett verktyg som kan utföra korttidsprognoser av översvämningar i Nedre Dalälven. I denna studie har en hydraulisk modell i programvaran HEC-RAS använts, här kallad för HEC-RAS NEDA. Den hydrauliska modellen fungerar bra till att användas för prediktering av vattenstånd i Nedre Dalälven. Valideringen av modellen mot värden under en testperiod med stor amplitud i vattenståndet visade att modellerade vattenstånd var inom ± 0,05 m från de uppmätta värdena. Modellen är stabil och klarar av att hantera 100-årsflöden med snabba flödesfluktuationer. HEC-RAS NEDA är ett noggrant och lätthanterligt predikteringsverktyg för översvämningar i Bysjön, Österviken och Färnebofjärden. Överensstämmelsen är god gällande nivån av vattenståndet och den fungerar bra för att studera hydrografens topp temporärt. Modellerade resultat har jämförts med karteringar som Sveriges meteorologiska och hydrologiska institut har gjort på Räddningsverkets begäran. Resultaten skiljer sig betydligt mellan HEC-RAS NEDA och Räddningsverkets modell, troligen på grund av att Räddningsverket har stora svagheter i indata till modellen. Räddningsverket har använt Geografiska Sverige Data-Höjddata och modellen HEC-RAS NEDA är framtagen med höjddata från en digital terrängmodell baserad på laserscanning. Areella studier i GIS över hur arean av vattenspegeln förändras med vattenståndet visar att Färnebofjärden under augusti år 2000 lade 55 km2 under vatten.

Les opérations de maintenance des routes en conditions hivernales sur réseaux routiers constituent un enjeu important pour maintenir l’offre de mobilité en situation dégradée. Elles génèrent des coûts d’exploitation directs et indirects élevés, liés en particulier à l’utilisation intensive de fondants routiers. Par ailleurs, leur impact environnemental doit être pris en considération. Nous étudions ici une structure de chaussée non soumise à ce type d’astreinte, grâce à la présence d’une couche de liaison drainante dans laquelle circule un fluide chaud, permettant ainsi d’éviter le dépôt de neige ou la formation de glace en surface. Dans le cadre d’une démarche en faveur de l’emploi d’énergie renouvelable, un tel dispositif pourrait permettre de récupérer l’énergie thermique disponible en surface de chaussée en période chaude, de l’acheminer vers un lieu de stockage (ex : géothermie) et de l’utiliser en période froide. Nous étudions ici la fonction d’échangeur de chaleur entre le fluide et la chaussée, la fonction de stockage externe à la chaussée n’étant pas abordée hormis dans la revue bibliographique. La structure de chaussée considérée comporte trois couches d’enrobés. La couche de roulement et la couche de base sont constituées de matériaux classiquement utilisés dans les chaussées, à base de liants hydrocarbonés. Le matériau de la couche de liaison possède une porosité supérieure à 20%. La structure de chaussée est supposée avoir un dévers de l’ordre de 2%. Une chaussée expérimentale instrumentée a été mise en oeuvre pour recueillir des grandeurs thermo-physiques de la chaussée. Un modèle thermo-hydrique 2D est d2veloppé numériquement pour calculer la distribution de température dans le corps de chaussée lorsque l’on injecte un fluide à température d’entrée donnée, en haut de dévers. Les paramètres du modèle sont identifiés à partir des données expérimentales recueillies sous diverses sollicitations climatiques. On analyse dans un premier temps la sensibilité de la distribution de température en surface de chaussée aux différents paramètres du modèle (conductivité hydraulique, dévers, conductivités thermiques, chaleurs massiques), afin d’optimiser les procédures nécessaires au contrôle sous contraintes de températures positives en tout point. Dans une deuxième partie, des données expérimentales recueillies durant une période estivale d’un mois ont servi à valider le modèle thermique 1D. Une maquette de laboratoire a également permis d’identifier des paramètres en milieu saturé et non saturé. La dernière partie de thèse est consacrée au calcul des quantités énergétiques récupérables pendant la période estivale à l’aide des données de la réglEmentation thermique RT2012. Elles sont comparées aux quantités énergétiques de chauffage nécessaires pendant la période hivernale en s’appuyant sur des données de la RT2012 et des données de la Direction Interdépartementale des Routes Massif (DIR MC) ; l’objectif final étant de déterminer les performances énergétiques du système. / Winter maintenance operations for road networks are an important issue for maintaining the mobility in degraded situations, but generate high direct and indirect exploitation costs, particularly related to the intensive use of road de-icing and environmental impact. We study a road structure free of this penalty, thanks to a bonding drainage asphalt layer, circulated by a hot fluid, to prevent the deposition of snow or ice formation on the road surface. As part of an integrated vision of promoting the use of renewable energy, such device could be used to recuperate the thermal energy available in the road surface during the hot period, to transport it to a storage location (e.g. geothermal) and use it during cold period. We study here the heat exchanger function between the fluid and the road, the external storage function to the road being not addressed. The considered pavement structure has three asphalt layers.The bearing layer and the base layer are formed of conventional materials with hydrocarbon-based binders. The material of the bonding layer has a porosity of 20% and based on the use of a binder resistant to a prolonged circulation of the coolant. The road structure is assumed to have a slope of about 2 to 3%. An instrumented experimental road is implemented to collect data on the thermo-hydraulic response of the pavement structure. A thermo-hydraulic 2D model is designed to simulate the temperature field in the road structure when the fluid is injected at the upslope side of the road with a target temperature. This model is calibrated from experimental data collected on the experimental road subjected to meteorological solicitations. Initially, the sensibility of the distribution of the surface temperature of the road toward various model parameters (hydraulic conductivity, transversal slope, thermal conductivities, heat capacities) is analysed, in order to study the optimization of control procedures allowing to keep positive the road surface temperature at any point (e.g. determination of the minimum fluid injection temperature, under given meteorological data). In a second time, pavement thermal parameters is identified using control optimal method in order to validated unidimensionnel thermal model applied on July experimental data. In third time, hydraulic model is validated experimentaly using a laboratory mockup in saturated and unsaturated conditions. In a fourth time, thermo-hydraulic bidimensionnal model is validated numerically using mesured data of experimental pavement. Finally, harvest energy in summer period using thermal reglementation RT2012 data and heating energy in winter period using RT2012 and Massif Interdepartmental Road Direction (DIR MC) are calculated in order to evaluate system performance.

The aim of the diploma thesis was the elaboration of a study of the rehabilitation of the sewerage network in the part of the town of Znojmo. The work is conceived in the form of accompanying and technical reports. The accompanying report contains a brief description of the interest site, basic information about the sewerage system operator and land data. The technical report contains a description of the individual segments of the sewer network, supplemented by photo documentation of the selected faults located on the selected sections. In addition, the evaluation of the structural state of the sub-sections is carried out here. The following subchapter draws up two hydraulic models and their modifications after the recovery of the sewer system. Another part of the technical report describes possible options for remediation technologies. The last part deals with the conclusions and recommendations for the sewer network operator including a briefly outlined economic page in the selection of remediation technology.

This diploma thesis deals with the study of the renewal of a selected part of the water supply network, specifically a section of the steel water supply line near the town of Velké Meziříčí. This study evaluates the current technical condition of the pipeline. Renovation is designed by selected rehabilitation technologies and renewal with the installation of a new pipeline. The thesis also describes the possible substitution of water transport during the shutdown of the part of the water supply network, including the mathematical model. Rehabilitation technologies are compared technically and economically. Also in terms of hydraulic parameters, using the EPANET 2.0 software application.

Water structure Ivanské jezero was built on the Javorník Creek back between 1905-1907. The main purpose of the dam was accumulation of high volumes of water and protection of the territory downstream. After the adjustment for higher flows on the river Kněžna in Rychnov nad Kněžnou, which was completed in 1937, the water structure lost the protective function. On the basis of an assessment made by Povodí Labe in 1993 - due to the low volume of the reservoir there is no flood wave transformation and already while flow rates greater than Q50 pass through dam, it results in overflowing the dam. To this date water structure Ivanské jezero is in very poor condition due to degradation of the binding material in the dam. The goal of the thesis is to propose a procedure for removal of the existing structure and the subsequent construction of the design and construction of a new – gravity, concrete dam. This work will contain technological removal process of current dam and possible usage options for the dam material. In the next step a new structure will be designed in the place of existing dam. After new design is completed there will be hydraulic assessment of the functional objects, hydrology and stability on the dam.

The diploma thesis is focused on the evaluation of the suppression of supercritical current energy in the area of the river bed extension. The hydraulic model was used to simulate current conditions for different variants of river bed arrangement. Individual variants were then evaluated according to the relevant criteria and compared with each other. Results can be applied in hydrotechnical practice based on model similarity.
