Runoff curve number (CN) is a parameter used in hydrology for predicting runoff from rainfall
excess, depending on the land use and soil type. Knowledge about the characteristics of the
watershed and its ability to generate runoff from rainfall is one of the key research topics in
hydrology. An important factor is the CN parameter. The CN parameter for the small
catchment Mačkov graben was determined using four different approaches: commonly used
empirical SCS method, which is based on land use and soil type, using rainfall-runoff data,
with asymptotic approach and with hydrological model, which was calibrated and validated
using the measured rainfall and runoff data. We have also compared and analysed the runoff
curve numbers, which were obtained with different methods. Useful values were between
60,7 and 74,5. Furthermore, analysis of the seasonality of the CN parameter were
performed. |
