Runoff changes simulated using a rainfall-runoff model
- 107 Downloads
The Sacramento rainfall-runoff model has been used in experiments with 60 year daily series for the Czech part of the Labe River basin; simulations with decreased and/or increased inputs (precipitations, air temperature, evapotranspiration) provide results that could be used to appraise the runoff changes due to climatic warming.
Simulations with the modified parameters are used for evaluation of runoff changes caused by landuse changes. For both purposes, the long-term data sets appear to be desirable; it is then possible to take into account ‘accidental’ influences. The simulations also provide, as an output, the water contents in different zones of soil moisture; the relationships among evapotranspiration, soil moisture, and baseflow clearly appear in these results.
