Rola retencyjności roślinności niskiej w formowaniu odpływu

The results of investigation on low vegetation interception role in flood generation are presented in the paper. The values of interception of low vegetation ranges from 10% to 30% of the prcipitation. Based on variable cover parameters (interception capacity and density), interception losses were calculated for individual floods. These values enabled runoff balance components and, consequently, catchment retention depth to be calculated. Low vegetation characteristics are presented along with a description of rainwater retention process on the plant surface, and an analysis of flood hydrograph with low vegetation interception loss influence on the magnitude of retention.
