Zusammenfassung |
Hydrological simulation in regions with a large number of water storages is
difficult due to inaccurate water storage data. To address this issue, this
paper presents an improved version of SWAT2005 (Soil and Water Assessment
Tool, version 2005) using Landsat, a satellite-based dataset, an empirical
storage classification method and some empirical relationships to estimate
water storage and release from the various sizes of flow detention and
regulation facilities. The SWAT2005 is enhanced by three features: (1) a
realistic representation of the relationships between the surface area and
volume of each type of water storages, ranging from small-sized flow
detention ponds to medium- and large-sized reservoirs with the various flow
regulation functions; (2) water balance and transport through a network
combining both sequential and parallel streams and storage links; and (3)
calibrations for both physical and human interference parameters. Through a
real-world watershed case study, it is found that the improved SWAT2005 more
accurately models small- and medium-sized storages than the original model
in reproducing streamflows in the watershed. The improved SWAT2005 can be an
effective tool to assess the impact of water storage on hydrologic
processes, which has not been well addressed in the current modelling
exercises. |
