Influence of enlargement and loss model on the flood hydrograph in a small hydrographic basin [articol]

Abstract

The study of the flood hydrograph is especially important in the case of small hydrographic basins, with a high risk of producing flash floods, following a torrential rain. In the formation of the flood hydrograph an important role is played by the choice of enlargement and loss model. The paper aims to study the influence of enlargement and loss model choice on the hydrograph’s duration and maximum discharge. For this purpose is used the MIKE11 model, the Rainfall-Runoff module, with the following options for choosing the enlargement and loss model (in UHM method): constant loss, proportional loss, SCS method and SCS generalized.
