Medientyp: E-Artikel Titel: Assessment on the function of reservoirs for flood control during typhoon seasons based on a distributed hydrological model Beteiligte: Wang, Guoqiang; Xu, Zongxue Erschienen: Wiley, 2011 Erschienen in: Hydrological Processes, 25 (2011) 16, Seite 2506-2517 Sprache: Englisch DOI: 10.1002/hyp.8023 ISSN: 0885-6087; 1099-1085 Schlagwörter: Water Science and Technology Entstehung: Anmerkungen: Beschreibung: AbstractA grid‐based distributed hydrological model, PDTank model, is used to simulate hydrological processes in the upper Tone River catchment. The Tone River catchment often suffers from heavy rainfall events during the typhoon seasons. The reservoirs located in the catchment play an important role in flood regulation. Through the coupling of the PDTank model and a reservoir module that combines the storage function and operation function, the PDTank model is used for flood forecasting in this study. By comparing the hydrographs simulated using gauging and radar rainfall data, it is found that the spatial variability of rainfall is an important factor for flood simulation and the accuracy of the hydrographs simulated using radar rainfall data is slightly improved. The simulation of the typhoon flood event numbered No. 9 shows that the reservoirs in the catchment attenuate the peak flood discharge by 423·3 m3/s and validates the potential applicability of the distributed hydrological model on the assessment of function of reservoirs for flood control during typhoon seasons.
