title: Regional evaluation of mass element fluxes: Geomon network of small catchments.
abstract: Monitoring of element flows and their mass balances in the natural unit of the biosphere represented by a small catchment appears to be the most suitable for the solution of complex problems such as the deterioration of environmental quality. Long-term collection of comparable biogeochemical data, which will enable the identification of environmental trends, is the main aim of the GEOMON network. One of the most important applications of these data will be the calculation of critical loads. The Czech Geological Survey possesses data from 44 catchments in the former Czechoslovakia. Qualitative and quantitative data on inputs in atmospheric deposition and outputs via surface runoff are available. Simple input-output mass balances yield estimates of total accumulation or loss of individual components. Some examples of interpretations of the GEOMON data, especially in connection with different bedrock types, will be given.
