Surface water body typology category river in the 1st and 2nd cycle of River Basin Management Plans and its consequence to ecological status assessment

Surface water body delineation and setting a typology are one of the initial steps during Water Framework Directive implementation (WFD) [1]. The first delineation and typology was prepared in 2004–2005 for the first plans, but all the results were significantly changed in the second cycle 2009–2010.

Quantifying the retention characteristics by the means of geomorphological patterns of the basin

In the presented study we tested the selected sets of linear and nonlinear regression models, that describe the relationships between the selected parameters of hydrological model Bilan, which were estimated using the meteorological, hydrological series, and between the retention characteristics estimated using the selected geomorphological patterns of the river basin.

Hydrological modeling of precipitation­‑runoff process in the “Husí potok“ basin

The aim of the project “QJ1520268 The new procedures of optimization system integrated protection area in the context of their economic sustainability“ is to create a design optimized system of anagement of water and soil resources in the long term, including balancing the soil‑plant‑atmosphere system and also in order to reduce the impact of climate change on agricultural ecosystem, which is highly topical issue today.

Water protection against nitrates from agriculture

The aim of Council Directive 91/176/EEC regarding the protection of waters against pollution caused by nitrates from agricultural sources [1] (hereinafter „Nitrates Directive“) is to reduce water pollution coming from agricultural sources and to prevent further such pollutions in order both to provide good­‑quality water supplies and to protect surface water against eutrophication.

Process of evaluation of runoff conditions and determination of design flows in the project Strategy for protection against the negative impacts of floods and erosion events by nature­friendly measures in the Czech Republic

Project The Strategy for protection against the negative impacts of floods and erosion events by nature­friendly measures in the Czech Republic comprehensively addresses the possibility of increasing water retention in the landscape.

Drought management and water reservoirs construction in the context of spatial planning

In the Czech Republic long-term protection of localities suitable for surface water storage (LASW) is done. Currently the number of them is 65; in the near future this list will be updated. The protection of these areas, however, has impacts on social and economic development of communities, local people and on the landscape itself, too.

Recent developments of the BILAN model

The BILAN model has been used in a number of research projects and hydrological studies dealing with estimation of water balance for European catchments. This paper is focused on the recent development of the model during last years. The model changes include both core development (new variables representing water use, optional calibration for a system of catchments, saving of state variables) and enhanced user interface that was extended by new graphical outputs and controls allowing interactive use of the model.
