TEMPORAL EVALUATION OF SNOW DEPLETION CURVES DERIVED FOR UPPER EUPHRATES BASIN AND APPLICATIONS OF SNOWMELT RUNOFF MODEL Marim, G&ouml / khan M.S., Department of Geodetic and Geographic Information Technologies Supervisor: Prof.Dr.A.&Uuml / nal Sorman September 2008, 112 pages Water is becoming very important issue day by day with descending usable water and energy resources. In the aspect of water resources management, especially for the optimum reservoir management, predicting runoff for large reservoirs by applying hydrologic model is a recent and crucial topic. The most important model input and predictor parameters to estimate runoff for the mountainous regions are to be distribution of rainfall / temperature and snow cover area, (SCA). It is seen that many predictor variables should be integrated with Geographic Information Systems (GIS) and Remote Sensing Techniques especially for hydrologic model variable preparation. Satellite products have the potential for obtaining those kinds of data in near real time. In this study, the changes of SDC are generated by the analysis of optical satellite and by using SDC as an input to hydrological models runoff is simulated for Upper Euphrates Basin (10215.7 km2) which is a sub basin of Euphrates Basin. Largest dams of Turkey / Keban, Karakaya and Atat&uuml / rk are located on Euphrates River. Optimum operations of these dams depend on forecasting incoming water in early summer season. Euphrates River is fed mainly from snowmelts in spring or early summer time.65-70 % of the annual flow is contributed from snowmelt in that region. Main objective of this study is to obtain the spatially and temporally distributed SCA percentages from optical satellite, which are required as one of the main input variables of the hydrological model used in the application. SCA percentages and SDC are obtained for snowmelt years 2004-2007 by using high temporal resolution optical remote sensing data: Terra Moderate Resolution Imaging Spectroradiometer (MODIS). In this study, Terra MODIS snow cover map product, MOD10A1 which has a spatial resolution of 500 m is used. As a hydrological model Snowmelt Runoff Model (SRM) was applied. SRM was built up on the well-known degree day approach. In this study SRM is simulated for two years 2006 and 2007.The simulation results are compared and resultant model parameters are obtained for future runoff forecast studies. In this study, beside recommendations, discussions on the variables and SRM parameters are also provided.

Snow indicates the potential stored water volume that is an important source of water supply, which has been the most valuable and indispensable natural resource throughout the history of the world. Euphrates and Tigris, having the biggest dams of Turkey, are the two largest trans-boundary rivers that originate in Turkey and pass throughout the water deficit nations Syria, Iran, Iraq and Saudi Arabia bringing life as well as water all their way. Snowmelt runoff originating from the mountains of Eastern Turkey accounts for 60 to 70 % of total annual discharge observed in Euphrates and Tigris. For an optimum operation of the dams, maximizing energy production, mitigation of floods and satisfying water rights, hydrological models which can both simulate and forecast the river discharges of Euphrates and Tigris are needed. In this study a hydrological model, snowmelt runoff model (SRM), is used in conjunction with remote sensing and geographic information systems to forecast the river discharges in the headwaters of Euphrates River, Upper Euphrates Basin. NOAA and MODIS satellite images were used to derive the snow covered area (SCA) information required by SRM. Linear reduction methodologies based on accumulated air temperature, with constant or varying gradient, were developed to get the continuous daily SCA values from the discrete daily satellite images. Temperature and precipitation forecasts were gathered from two different numerical weather prediction models, namely European Center for Medium Range Weather Forecasts (ECMWF) and Mesoscale Model Version 5 (MM5) from Turkish State Meteorological Services. These data sets provided t+24 hour forecasts of both temperature and precipitation. Temperature, precipitation and SCA information are fed into SRM. Discharge forecasts obtained from the model outputs are compared with the observed values. The overall performance of the model was seen as promising. Possible reasons of the mismatches between the forecasted and observed values are searched. Experiences gained throughout the study are summarized and recommendations on further forecast studies are mentioned.

La vallée du moyen Euphrate, trait d’union entre la Mésopotamie du sud et la Syrie occidentale, est, durant la fin du la fin du IIIème millénaire et le début du IIème millénaire, gouverné par un šakkanakku installé à Mari (Tell Hariri, Syrie). Cette époque ainsi nommée « époque des šakkanakku » est, depuis deux décennies, étudiée avec un intérêt grandissant, en raison des découvertes archéologiques datant de cette époque. Une vue d’ensemble des données archéologiques et historiques de vallée du moyen Euphrate durant l’époque des šakkanakku suggèrent que le royaume de Mari, durant cette époque, s’est affirmé comme une puissance indépendante et prospère jusqu’au 19ème siècle (fin de l’époque des šakkanakku) où les données sont moins explicites sur le plan historique. Grâce à de nouvelles données textuelles provenant de Mari, mais également de Terqa (au nord de Mari) dont la majorité date de la fin de l’époque des šakkanakku, on a pu mettre en évidence des permanences et des ruptures entre la fin de l’époque des šakkanakku et l’époque suivante (époque « amorrite ») dans plusieurs domaines comme la langue, la « tradition scribale » ou encore dans la tradition juridique. Du point de vue dialectal, les textes du 19ème siècle montrent que la tradition linguistique est fortement ancrée dans l’univers syrien. Après l’avènement de l’amorrite Yahdun-Lim qui mit fin à l’époque des šakkanakku, la composante syrienne demeure présente, mais elle reste moins importante en raison d’une réforme de l’écriture modélisée sur la pratique sud mésopotamienne (Iraq actuelle), certainement due à la prépondérance politique d’Ešnunna durant l’extrême fin du 19ème siècle. Enfin, cette nouvelle documentation a également permis d’aborder des questions plus historiques notamment l’interaction des derniers šakkanakku de Mari avec des condottieres amorrites dont le père de Yahdun-Lim durant le 19ème siècle. / The valley of the Middle Euphrates, hyphen between South Mesopotamia and Western Syria, was ruled by a šakkanakku lived in Mari (Tell Hariri, Syria) during the end of the third millennium and early second millennium. This time period named "šakkanakku-period" is particularly studied since twenty years An overview of archaeological and historical data from the Middle Euphrates valley during the time of šakkanakku suggest that the kingdom of Mari during that time has established itself as a power independent and prosperous until the 19th century (end of the time of šakkanakku) where data are less explicit historically. The new text data from Mari, and Terqa (north of Mari), of the most dated from the end of šakkanakku-period, shows continuance and ruptures between the end of šakkanakku-period and the next period ("Amorite-period"). This continuance and ruptures are examined in several areas such as language, "scribal tradition" or in the legal tradition. The dialect of this text (19th century) shows that linguistic tradition is deeply rooted in the universe Syria. After the advent of the Amorite Yahdun-Lim who ended the time of the šakkanakku the Syrian characteristics in the dialect remains present, but it is less important because a reform of writing modeled on southern Mesopotamia (Iraq current), probably due to the preponderance of political Ešnunna during the end of the 19th century. Finally, this new text has also allowed dealing the historical interaction of the last šakkanakku Mari with condottieri Amorite whose father Yahdun-Lim in the 19th century.

Temperature and precipitation are the most important indicators of climate change. Especially for the basins fed by snow, the shifts of melting to earlier times, affects the streamflow. Increase in temperature causes to shifts of melting of snow to shift to earlier times so that hydrologic regime of the river system changes, and leads to changes in climatic conditions of the region. In this study the shifts of snow melting times are analyzed for the selected 15 streamflow stations located in Euphrates, Tigris, Aras, and &Ccedil / oruh basins in Eastern Anatolia of Turkey along with period from 1970 to 2010. The shifts in snowmelt runoff are determined by Center Time (CT) method. Meteorological stations representing the stream gauge stations regarding the basin characteristics are also selected to be used in the analyses. In order to relate CT shifts to temperature and precipitation changes, trend analysis are applied to temperature, precipitation and streamflow data. In addition to these, days with daily average temperature less than freezing and wet days below freezing until CT for each station pair between stream gauge and meteorological stations and each year are also analyzed. These days till CT within a year for each station pair can be indirectly linked to snowy days and accumulated snow amount. Complete analyses show significant warming at each station in the region and no important trends in annual precipitation. However at a few stations meaningful seasonal changes in precipitation are observed. Regional warming and associated changes in precipitation and snowmelt runoff cause significant shifts to earlier times of snowmelt runoff. In the region eight out of fifteen stream gauge stations in Euphrates, Tigris and Aras basins showed significant time shifts according to statistical trend tests.

Une monographie sur la ville antique de Sura s’imposait pour mettre l’accent sur un site-clef, peu étudié, parmi les villes fortifiées du Moyen-Euphrate. L’objectif de ce travail est d’en offrir une description et une analyse poussées et d’élargir le champ des recherches à l’ensemble de la région. À 22 km à l’ouest de Raqqa et à 29 km au nord de Resafa, à l’emplacement du village moderne d’«el-Hammam», Sura (autrefois «Souriya») domine la rive droite de l’Euphrate. Le site est une agglomération fortifiée de forme rectangulaire (76,5 ha) divisée en deux parties, enceinte nord-est et enceinte sud-ouest. Nous présentons Sura de l’époque romaine jusqu’au début de l’époque omeyyade (Ier-VIIIe s.), d’après les résultats de nos recherches qui, entre 2003 et 2011, se sont concentrées sur trois pôles : fortifications, structures domestiques et édifices civils (fouilles intra-muros), nécropole(fouilles extra-muros). Nous étudions ensuite sa culture matérielle à travers le mobilier archéologique et les éléments architecturaux issus des fouilles. Les résultats de ces recherches doivent enrichir le dossier des sites de référence de l’Antiquité tardive pour la région de l’Euphrate et de la Syrie du Nord, en offrant une base de comparaison de premier ordre pour l’architecture civile et funéraire et, surtout, pour le matériel céramique, le verre, les inscriptions. Occupant une position géographique stratégique, Sura fut florissante pendant l’époque romaine et byzantine, jusqu’à la conquête arabe de la région en 639-640, qui scella son déclin – contrairement aux autres villes de l’Euphrate –, puis elle ne fut plus occupée que par des chrétiens locaux, dans des habitats modestes. / A monograph about the ancient city of Sura was necessary in order to bring to light a site little studied so far, in spite of its key importance among the Middle Euphrates fortified towns. The present work aims at offering a thorough description and analysis of it, while broadening the scope of comparison to its larger region. Sura(previously “Suriya”) is situated 22 km west of Raqqa and 29 km north of Resafa, on the location where nowadays stands the village of “el-Hammam”, overlooking the right bank of the river Euphrates. The site, a fortified agglomeration of rectangular shape (76,5 ha), is divided into two parts, the northeast and the southwest enclosures. We present Sura from Roman times until the beginning of the Umayyad period (1st-8th cent.), through the results of our researches, which, from 2003 to 2011, have been focusing, intra-muros, on its fortifications, on its domestic and public structures, and, extra-muros, on its necropolis, then through its material culture, that is, thesmall finds and architectural elements. Such a research should contribute to enhancing the extant knowledge about Late Antiquity in the Euphrates region and North Syria, by bringing forth an additional reference site, especially for civil and funerary architecture and, above all, pottery, glass, and inscriptions. The floruit of Sura, set in a strategic location, lasted from the Roman through Byzantine times, until the Arab conquest of the region, in 639-640, threw it into oblivion – a fate not shared by other cities on the Euphrates. Afterwards, only local Christians maintained some modest settlement there.

Desde 1989, entre las labores realizadas por la Misión Arqueológica Española en Siria se encontraba un programa de prospección y estudio del territorio, en el cual se enmarcaban los yacimientos donde se estaba excavando (Tell Qara Qūzāq y Tell Jamīs). Este programa abarcaba una amplia zona de terreno y también un extenso marco cronológico. Aprovechando esta investigación arqueológica en el Éufrates se pudo constatar la existencia de numerosas cuevas labradas, de índole funeraria algunas y monacales otras.A raíz de esta línea de investigación inicial, esta Tesis ve la luz desde el Instituto del Próximo Oriente Antiguo que me ofreció la posibilidad de estudiar directamente todos los restos de época romana y bizantina que se habían localizado en sus continuas excavaciones y prospecciones en Siria, concretamente en el entorno de Qara Qūzāq. / Since 1989, among the works carried out by the Spanish Archaeological Mission in Syria, was an program of surveys and study of the territory in which there was digging (Tell Qara Quzaq and Tell Jamis). This program didn't only include a wide land area but also an extensive chronological horizon. This way, taking advantage of this archaeological research in the Euphrates you could verify the existence of numerous figured caves, of funeral nature some and monkish others. Soon after this line of initial research, this Thesis sees the light from the Instituto del Próximo Oriente Antiguo (IPOA) that offered me the possibility to study directly and in more intensity all the remains of Roman and Byzantine time that had been located in its continuous excavations and surveys in Syria, concretely in Qara Quzaq's environment, main centre of the archaeological mission from where the IPOA acted in this region.

Cette thèse a pour objectif d’étudier la « figure du roi » au travers de documents iconographiques du Bronze Moyen provenant de Syrie et plus particulièrement de la zone du Moyen-Euphrate entre 2000 et 1600 avant J.-C. Notre approche méthodologique qui porte prioritairement sur la partie sigillaire a consisté à établir un corpus des plus exhaustifs possibles des sceaux publiés et inédits. Après l’établissement de celui-ci, nous opérons des comparaisons pour dégager les caractéristiques de la représentation royale. Dans un premier temps, le cadre spatio-temporel retenu pour cette étude est défini. Par la suite, nous effectuons une mise au point sur l’histoire de la question de la représentation royale dans la glyptique syrienne du Bronze Moyen. Le développement qui suit constitue la cible de cette thèse. Les objets qui servent de base à cette étude viennent de vingt cinq sites archéologiques différents. Les sites de Moyen-Euphrate syrien, divisés en deux ensembles : partie nord et partie sud couvrant la zone-clefs de cette thèse, ont été soigneusement étudiés. En suite et afin de mieux définir la « figure du roi » dans l’iconographie, des moyens d’identification ont été décrits. La suite comporte une analyse de toutes les représentations de la figure royale, que nous tentons de définir par type. Le paragraphe présentant chaque modèle est suivi d’un tableau montrant l’aire de diffusion au sein de l’aire géographique concernée. Suit un inventaire des multiples aspects de cette iconographie royale, au sein duquel on distingue des : 1. Modèles dominants: le roi à la masse d’arme, le roi vainqueur, le roi-orant et le roi de type « syrien » que nous tentons de définir.2. Modèles dérivés: le roi-porteur d’offrande, représentation royale avec une divinité féminine, le roi-pharaon de type «égyptien », les cas de la duplication de la figure royale.Par ailleurs, une étude des « personnages incertaines » que nous expliquons est également menée. La présence de multiples divinités aux côtés des rois nous a conduits à en effectuer l’inventaire et à en préciser dans la mesure du possible l’iconographie, le cas échéant à préciser la nature des cultes qui leur étaient rendus. Cependant, des questions importantes, comme la compréhension de certaines réalités telles que la question complexe de la« divinisation ou non du personnage royal », ou les « Dieux politiques » ont été posées. De plus, des problèmes tels que le rite de « kispûm » ou la question de « Dieu de roi » ont été abordés. Parmi nos conclusions les plus importants on souligne : l’aspect régional de l’image du roi en Syrie, le rapport particulier entre l’archéologie et la glyptique ainsi que le fond sacré de l’idéologie royale de l’époque amorrite. Au niveau de l’organisation de cette thèse, notre premier volume est accompagné d’un second volume représentant le catalogne des matériels étudiés (env. quatre cent objets). L’ensemble est complété par deux index et de références bibliographiques. / This doctorate (Ph.D.) research studies the representation of Syrian kingship during the Amorite period (ca. 2000-1600 B.C), essentially through glyptic evidence, supplemented by sculpture, wall paintings, and written sources from the same period.The methodology is anchored in defining a precise iconographic corpus. This step allows revising past conclusions and establishing new identifications for the king’s role in artistic as well as written expressions. A major accomplishment is the identification of objects that derive from clear, stratified archaeological and cultural contexts.After defining the spatial and chronological frame, this study offers a brief review of the twenty-five sites from which the material is assembled. They are located in the Middle-Euphrates valley and divide between those in the northern and southern segments. Characteristics for a “royal figure” are identified and then defended. Iconography permits to distinguish diverse models of the “royal for each of the Syrian regions.The models divide into:1. Main models: the warrior-king, the king-priest, the king of “Syrian” type2. Secondary models: royal officials or the “duplication” of the royal figureIn addition, “miscellaneous figures” are also classified.On the epigraphic level, in this study there is liberal use of information from the archive of Mari as well as of Terqa, discriminating between materials derived from epistolary, religious, political, and administrative documents, as the ruler acts as a priest, dispenser of justice, warrior, or family man. A special chapter is devoted the interrelationship among kings, personal, and state gods. There is also consideration of funerary rituals (kispum) as well as the issue of the deified king.The study takes into consideration the following issues: the royal image of Syrian kings as shown in regional perspective, the connection between glyptic arts and their archeology, and the religious basis of royal ideology during the Amorite period.The dissertation includes a second part in which is catalogued over four hundred iconographic objects or images. Bibliographic references and indexes complete the study.
