The presented article deals with the catchments of three streams, which are right-hand tributaries of the Černá Opava river, where new foresthydrology research activities of the Forestry and Game Management Research Institute and Czech Hydrometeorological Institute begun. The focus of the work in the years 2019–2021 was on field research and measurements, spatial analyses in GIS and mathematical modelling using rainfall-runoff and hydrodynamic models, thus we can mention HEC-HMS, SIMWE and MIKE SHE/11 models among others. The article provides an overview of current outputs from these activities. It also outlines the issues of the impact of land use, forest health including its extreme phases on hydrological conditions and the response of river basins to precipitation inputs. Besides that, the issue of variable contribution areas of the river basins and the possibilities of their research at the level of monitoring (e.g. measurement of flows and volumetric soil moisture) and mathematical modelling using complex fully distributed precipitation-runoff models are discussed as well. At the same time, basic hydrological characteristics of the studied catchments were provided.
