Towards a Web Decision System Support for Planning Micro-Watershed Using Pressure-State-Response and Logic Fuzzy, Study Case in Colombia

Abstract

This paper presents a conceptual web decision support systems (DSS) for assessment of a tropical Andean micro-watershed. A combination of pressure-state-response (PSR) indicators and logic fuzzy were used. Three indices were defined: climate change (ICC), quality water (IQW) and soil degradation (ISD). Each index is a combination of qualitative and quantitative indicators. Fuzzy functions were defined to generate operability in each index. Trapezoidal, triangular and singleton functions were defined. The inputs are the indicators value in each zones of the watershed: high zone, medium zone and low zone. Outputs of WebDSS are the value of each index. The Web DSS was applied in an Andean watershed named "El Chocho", in Colombia. The results indicate the high degradation level in the watershed, evidenced by the indices values. This study indicates the possibility of building and applying a DSS to support management decision process in Andean microwatersheds.
