Hillslopes are one of the basic units that mainly control water movement and flow pathways within catchments. The structure of their shallow subsurface affects water balance, e.g. infiltration, retention, and runoff. Nevertheless, there is still a gap of knowledge of the hydrological dynamics on hillslopes, notably due to the lack of generalization and transferability. To improve the knowledge of hydrological responses on hillslopes with periglacial cover beds, hydrometrical measurements have been carried out on a small spring catchment in the eastern Ore Mountains since November 2007. In addition, surface ERT measurements of several profiles were applied to enhance resolution of punctual hydrometric data. From May to December 2008 geoelectrical monitoring in nearly weekly intervals was implemented to trace seasonal moisture dynamics on the hillslope scale. To obtain the link between water content and resistivity, the parameters of Archie's law were determined using different core samples. To optimize inversion parameters and methods, the derived spatial and temporal water content distribution was compared to tensiometer data and resulting in remarkable coincidence. The measured resistivity shows a close correlation with precipitation. Depending on the amount and intensity of rain, different depths were affected by seepage water. Three different types of response to different amounts of precipitation (small, medium, high), could be differentiated. A period with a small amount causes a short interruption of the drying pattern at the surface in summer, whereas a medium amount induces a distinctive reaction at shallow depth (<0.9 m), and a high amount results in a strong response reaching down to 2 m.

Ziel der Arbeit ist es, ein genaueres Prozessverständnis zur Abflussbildung an Hängen auf der Basis der räumlichen Verbreitung periglazialer Deckschichten zu erhalten. Das Untersuchungsgebiet ist ein 6 ha großes, forstlich bewirtschaftetes Quelleinzugsgebiet im Osterzgebirge. Das anstehende Gestein ist Gneis. Der oberflächennahe Untergrund ist aus zwei- und dreigliedrigen Deckschichten zusammengesetzt. Auf der Punkt-, Hang- und Kleineinzugsgebietsskala werden hydrometrische, hydrochemische und geoelektrische Methoden sowie Färbeversuche eingesetzt, um auf die dominierenden Abflussbildungsprozesse schließen zu können. Aus der Synthese der Teilergebnisse werden drei typische Prozessabläufe in Abhängigkeit von der Gebietsvorfeuchte abgeleitet. Diese verdeutlichen, dass bei geringer Vorfeuchte Sättigungsoberflächenabfluss im Quellsumpf vorherrscht, bei mittlerer bis hoher Vorfeuchte dagegen Zwischenabfluss der dominierende Abflussprozess ist. Die Abflusswirksamkeit der Niederschläge steigt zudem mit zunehmender Vorfeuchte nichtlinear an. Es wird herausgestellt, dass die hydraulisch anisotropen Eigenschaften der Basislage entscheidend die oberflächennahen Fließwege des Wassers beeinflussen. Sie besitzt durch ihre hohe Lagerungsdichte einerseits vertikal wasserstauende Eigenschaften. Andererseits kann Wasser, begünstigt durch das dominant sandige Substrat und das hangparallel eingeregelte Bodenskelett innerhalb der Schicht bevorzugt lateral geleitet werden. Die gewonnenen Erkenntnisse verdeutlichen die Bedeutung der Eigenschaften der periglazialen Deckschichten für die Abflussbildung an Mittelgebirgshängen. / The aim of this study is to contribute to the understanding of runoff processes on slopes based on the spatial distribution of periglacial cover beds. The study area is a 6 ha large forested spring catchment in the Eastern Ore Mountains, Saxony. Bedrock is gneiss overlain by periglacial cover beds comprising two or three layers. On plot, hillslope and small-catchment scales hydrometrical, hydrochemical and geoelectrical methods as well as tracer experiments are used to determine the constitutive runoff processes. From the synthesis of partial results, three pre-moisture controlled process cycles are derived. With low pre-moisture, saturation overland flow dominates in the spring bog. In contrast, with medium or high pre-moisture interflow occurs. Besides, with rising pre-moisture runoff coefficients increase in a non-linear manner. It is emphasised that the hydraulic anisotropic structure of the Basal Layer is the major control factor for subsurface water-flow paths. On the one hand, this layer acts as an aquitard for seeping water because of its high bulk density. On the other hand, water within the layer is able to flow laterally because of the sandy texture and the coarse clasts oriented parallel to the slope. These findings highlight the importance of relic periglacial cover beds for runoff generation in subdued mountains.

Diplomová práce Vztah obyvatel k místu 5 Abstract This thesis entitled "Relationship of inhabitants to their home place in Eastern and Western Ore Mountains (Krušné hory)" focuses on the issue of a relationship the current inhabitants have to the area they live in. This relationship is defined on the basis of several distinct theoretical areas. The first portion of the thesis covers the basic terminology key for understanding the relationship of inhabitants to their home place. It deals with the definition of the term "home place", its character and ways in which it may be perceived. It also contemplates the term "settlement" and focuses on "identity" which is further defined as biographical and regional identity. Identity may be studied in the context of a relationship to the countryside, local community and historical awareness. The paper also characterises the Sudetenland region and provides the historical context necessary for a comprehensive outlook at the area researched without marginalizing the issue of nationalism. The practical portion employs qualitative methodology to process eighteen semi-structured interviews with representatives of elites (mayors, businessmen and members of associations) of the selected are of the Eastern and Western Ore Mountains. Subsequent analyses point to identical and...

An assessment of tin-skarn resources in the Erzgebirge, Germany, was conducted with the 3-Part Method. For this purpose a Grade-Tonnage Model for this deposit type was established. A literature review produced grade and tonnage data for 23 skarn deposits, of which 9 are in the assessment area. Based on an existing predictive map created with an AI algorithm, seven permissive tracts with a total area of 776 km² were defined. To estimate the number of undiscovered deposits a panel of five experts in the economic geology of the Erzgebirge was assembled. From the expert estimates and the newly developed Grade-Tonnage Model the undiscovered ore and metal tonnages in each permissive tract were evaluated. In four of the seven tracts the probability of the existence of at least one undiscovered deposit is estimated to be greater than 50%, in permissive tract 2 it is even greater than 90%. In each of these tracts, the median assessed undiscovered ore tonnages are several million tons and the tin resources exceed 10,000 tons. For the most perspective tract (Permissive tract 2) the median estimates are 40.6 Million tons of ore with a tin content of 114,000 tons. For tungsten (tonnages calculated as WO3) the numbers are slightly lower. The results verify the high resource potential of tin skarns in the Erzgebirge and can be used to guide future exploration activities to the most economically promising permissive tracts.
