Transport of suspended sediments in various regions of the Czech Republic

Abstract

The paper aimed at comparing the transport of suspended sediments in four model river basins, which are mutually comparable as to their area (350-400 km2) and also represent different geographical environments within the territory of the Czech Republic. For model river basins were developed erosion risk models based on a multi-criterion scale evaluation of chief erosion factors and were implemented as a grid models in the GIS environment. The suspended sediment transport was evaluated for closing profiles of model river basins, mostly for a hydrological period 1985-2000. We defined basic types of run-off situations to characterise the relationship between the content of suspended sediments and the water flow.
