Hydrometeorological - Hydrometric Station Network Design Using Multicriteria Decision Analysis and GIS Techniques

The design of an optimum hydrometeorological and hydrometric station network constitutes a key factor for the collection comprehensive reliable flow data that are necessary both decision making in water resources policy management, risk assessment. This article describes methodology developed geographic information system (GIS) using multicriteria (MCDM) approach, which combines several spatial criteria to propose suitable locations installation such Sarantapotamos River Basin western part Attica Region, Greece. Through two networks meet different requirements, various aspects concerning this illustrated, as weights determination, is problem arises frequently many MCDM techniques. estimated Analytic Hierarchy Process (AHP) Fuzzy (FAHP), while, design, all equal. Hydrometeorological final position selection achieved by introducing density distribution locations. For analysis indicates criterion slope mainly controls outputs. According thresholds proposed World Meteorological Organization (WMO), region should comprise three stations, respectively.
