The impact of small reservoirs on groundwater level and overall hydrological balance with emphasis on dry periods

The project assesses the impact of small reservoirs on the hydrological balance and its components at different spatial scales. The project is being implemented between 2019 and 2021; it is funded by the Technology Agency of the Czech Republic.

Project background

How do small reservoirs affect their surroundings? Research should contribute to a comprehensive and quantitative assessment of the positive and negative aspects associated with the presence, operation, and construction of small reservoirs near settlements and in the agricultural landscape.

Project aims

The project assesses the impact of small reservoirs on the hydrological balance and its components at different spatial scales. The assessment is performed in the vicinity of small reservoirs, in source river basins, and in river basins with systems of ponds and small reservoirs. The hydrological balance is focused on determining the effect of small reservoirs on groundwater levels, evaporation, and runoff.

Activities are based on monitoring selected hydrological indicators at small reservoirs, analyses of the immediate vicinity of small reservoirs through remote sensing data, estimation of hydrological balance components by hydrological models together with description of uncertainties, estimation of physical and geographical characteristics of small reservoirs and affected river basins, and regional analysis of small reservoir characteristics.

The research aims to contribute to a comprehensive and quantitative assessment of the positive and negative aspects associated with the presence, operation, and construction of small reservoirs near settlements and in the agricultural landscape.

Project methodology

Based on field data, the research aims to contribute to a comprehensive and quantitative assessment of the positive and negative aspects associated with the presence, operation and construction of small reservoirs near settlements and in the agricultural landscape.
