Development in and status of surface waters in an important drinking water source area

The paper discusses changes in of the basic parameters of surface water within the important drinking water source area of hydrogeological unit 232 Ústecká syncline, in the Svitava river basin. Emphasis is placed on the changes in the amount of water in the Svitava river and the changes in the basic physical and chemical parameters of these waters. The possible effect on local groundwater, which is intensively used for drinking purposes, is discussed. The contribution compares historical data sets with the results of current monitoring within the project SS06010044 (PPŽ VI, TA CR). The current qualitative state of surface water points to caution in promoting direct infiltration into groundwater due to the risk of contamination.

Interpolation of selected discharge rates in ungauged fourth-order catchments in the Otava basin

Knowledge of catchment runoff values is the key to a wide range of engineering and scientific applications. However, direct measurements in the scope of all fourth-order catchments in the Czech Republic are not realistic. Standard methods for estimating these parameters are local regression models, rainfall-runoff models, or other interpolation techniques. Regression models provide reliable results, but the derivation of local regression equations is demanding on the amount of input and reference data. Rainfall-runoff models have their application in design activities at a local scale. Their application in the Czech Republic is not trivial and requires knowledge of precipitation distribution. Interpolation techniques provide a fast but often less reliable approach. Most of these interpolations are not primarily intended for hydrological applications; the exception is the Top-Kriging method.

Interview with Mgr. Mark Výborný, Minister of Agriculture

Mr Výborný is participating in preparations for the construction of new reservoirs in the Czech Republic and is planning to build new pumped storage waterpower stations. According to the Minister, the priority in the field of water management is mainly the development of water supply and sewerage infrastructure, including drinking water treatment plants and wastewater treatment plants, technological measures to retain water in the landscape, construction and restoration of small water reservoirs and ponds, development of water supply systems, and also the modernization of existing irrigation systems. Mgr. Marek Výborný told VTEI about his first year as Minister of Agriculture and the objective he would like to achieve in this position.
