Topographic data play an important role in the hydrodynamic modelling of flood events. An accurate and precise digital elevation model (DEM) with a bathymetric description of the river channel is often required. DEMs can be derived from various data sources, e.g. ground surveying or remote sensing techniques.
Water quality of the Prague’s streams. Part 2: tributaries to the Šeberák pond and to the Hostivař reservoir
The possibility of a recreational use of some of the Prague reservoirs is limited mainly by the quality of the tributaries. The article follows the previous one and sums up the results of the water quality monitoring in selected profiles of the tributaries of the Šeberák pond (the Vestecký and the Kunratický streams) and of the Hostivař dam (the Botič and the Pitkovický streams) during 2018.
Biowaste or waste subject to the anaerobic or aerobic decomposition has become a problematic component of the municipal waste due to the use of green spaces, especially in the large cities with a high population density.
