Response variability of selected hydrological models to typical temporal distributions of short-term precipitation

The article presents a selection of outcomes of a three-years’ project named “Variability of Short-term Precipitation and Runoff in Small Catchments and its Influence on Water Resources Management“. Its aim was to provide to the public the newly derived typical temporal distributions of subdaily precipitation, also known as design rainfalls.

Classification of small watersheds for the rainfall-runoff modelling in the Czech Republic

This article introduces a classification of small watersheds in the Czech Republic in terms of potential hydrological response to a set of design precipitation time series. Watershed classes as well as precipitation time series were derived as a partial result of a three-year project aimed at the design of typical soil conservation measures and small water management structures

Baseflow evolution from the part of Bohemian-Moravian Highlands

This article is focused on evolution of baseflow from part of the Bohemian-Moravian Highlands. This is a topical issue and, given the current situation, is also often discussed. The problem of groundwater and its recharge is an important (not only) hydrogeological problem, as climatic conditions in recent years, especially low precipitation, have a negative impact on groundwater recharge.

Hydrological balance and available water resource in the czech republic during hydrological drought

The article deals with the assessment of the hydrological balance in a monthly time step in the territory of the Czech Republic, which was divided into 133 sub-basins for the period 1981–2015.

Policy of Protection from impacts of drought and water scarcity in the Czech Republic – consultation and processing

In the context of a severe drought period, which has started in 2014, an inter-ministerial commission WATER-DROUGHT was established to prepare a strategic policy document on protection from impacts of drought and water scarcity in the Czech Republic.

Evaluation of the impacts of drought on aquatic and water-bound organisms in surface water bodies

Within the framework of the sub-task “Evaluation of the impacts of drought on aquatic and water-bound organisms in surface water bodies“ a project involving activities to support the state administration in the drought issue in 2016 was prepared mainly a review of the potential impacts of drought on individual elements and indicators of water status assessment.

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.
