Hydrologic modelling in GIS
 LIPPL, Jan
The purpose of this work was to present the computer supported hydrological simulation. The methods are demonstrated on the Jenínský stream catchment, which serves as an experimental catchment of the Depatment of Land Adjustement, Faculty of Agriculture, University of South Bohemia since 2004. The hydrological analyses are solved in the ArcGIS 9.2 software, ArcView level and its extension ArcHydro. Digitized contour lines layers, watershed divide and the stream were used as a basis for functionality testing. Subsequently the results were compared with the reality, and the possible differences were discussed. The result is evaluation of the use of particular tools of the mentonioned software for the tasks solved in catchment hydrology. This work will also be used as a guideline for the use of ArcHydro for the extension of the education of modelling in the subjects concerning catchment hydrology.

Causes of long-term increase in concentrations of dissolved organic matter in Římov Reservoir
 Hejzlar, Josef ; Kopáček, Jiří ; Porcal, Petr ; Haider, Z.
The concentration of dissolved organic matter (DOM) has increased in Rimov Reservoir since the late 1980s. Two main reasons were revealed for this increase: (i) an increase of DOM concentrations in the reservoir inflow that has been caused by more frequent summer high-runoff and DOM-rich events, and (ii) an increase in temperature and surface runoff volumes during winter months. The effects of decreasing atmospheric acid deposition and changes in farmland practices in the catchment also cannot be excluded as the other sources for the increase.
