River basin management is at present of great importance as a response of the increased frequency of extreme hydrological events in a changing climate. The emerging need for streamflow control awaits a capable hydrological outcome.
Data collection and processing are the essence of a proper representation of the hydrological processes in a watershed. The main objective of this study is to introduce an approach for a watershed spatial variability processing hence determining the parameters for building up a hydrological model. The ArcSWAT geographic information system (GIS) interface for the Soil and Water Assessment Tool is used. Geographic Information System (GIS) is a very successful tool for analyzing spatial relationships between important hydrologic features such as rivers, diversions, drains and monitoring points. The ArcSWAT model is a geodatabases system storing the Soil and Water input information and results. The Soil and Water Assessment Tool (SWAT) is an open source watershed scale, semi-distributed hydrological model. Preprocessing of the initial inputs to the SWAT model via the ArcSWAT GIS interface is presented in this paper: digital elevation model set-up for a selected watershed, soil properties and landcover data processing, integration of the attributed data, determining the basic hydrologic parameters for which SWAT model calculations are performed. Statistical evaluation and analysis of the outputs are also presented together with outlines for their further use. |
