Extinct Ponds: Estimating Average Discharge Values for Purposes of their Water Balance Assessment in Order to Improve Management of Water Resources

Vaclav David

Abstract :

This paper presents the development of the methodology for estimations of runoff characteristics of small to medium catchments including all calculation procedures and methods applied for this purpose. The purpose of this analysis consists mainly in the assessment of reservoirs water balance which is one of tasks within the complex assessment of the possibility of extinct ponds restoration. For the development of the methodology for mean runoff value calculation, the multiple regression approach was adopted. Four catchment characteristics were considered as independent variables. These are catchment area, mean annual precipitation, mean annual temperature and percentage of forests which are assumed as important for mean runoff calculation. Derived equation achieved after parameterisation the value of R2 = 0.84 in case of the most complex model structure. However, good results were achieved also in case of simpler model structure.
