The use of NRCS synthetic unit hydrograph and Wackermann conceptual model in the simulation of a flood wave in an uncontrolled catchment

摘要: The paper presents the results of using two models: a conceptual model Wackermann and NRCS-UH synthetic unit hydrograph, for flow calculation in uncontrolled catchment Slonka, Poland. These models were chosen because simplicity models’ parameters evaluation, what is important from engineering point view. Flows with probability exceed amounting to 0.5%, 1%, 2%, 5%, 10%, 20%, 50% different levels moisture evaluated. flood waves generated characterized by short duration (over 2 hours), shorter concentration time (about 1 hour), about 70% higher peak values than those method. A common feature both methods flows third level moisture, as compared second level. It also worth noticing that no wave was probabilities 10, 20 moisture. assumed hydrographs made use better describe mountain river, which Slonka is.
