Spatial planning and decision support system for modeling water resources

Sustainable water resources management is very crucial nowadays by looking at the current problems associated with water resources such as water supply water quality water demand etc. Numerous studies have been undertaken pertaining to water resources management but only few studies are related to planning the water environment. Recent advances in GIS Geographic Information System technology and the remarkable achievement of several operational research techniques that can be applied together with GIS have enable the state-of-art of water environmental planning to be enhanced beyond the existing practices. The combination of GIS and Multi-Criteria/Objectives Decision making MCDM/MODM methods with a special reference to the Analytic Hierarchy Process AHP technique have resolved many issues pertaining to unstructured and ill-defined data sets of water environmental planning. An attempt to integrate GIS and AHP as a Spatial Planning and Decision Support System SPDSS model for land use planning was initiated in the early 1990s. The model was then applied to study the conservation of water resources in Selangor state by using five distinctive sets of criteria namely water catchment area slope altitude land use and aquifer area. Although the result is encouraging but there are more related criteria have to be considered. The recent study has made improvement to the criteria data sets by incorporating soil class into the model. A comparative analysis of maps results is carried out to examine the change of land uses due to the change of parameters. It shows more environmental sensitive and vulnerable areas in the present land use i.e. intrinsic suitability of land that deserves for protection.

Abstract

Sustainable water resources management is very crucial nowadays by looking at the current problems associated with water resources such as water supply water quality water demand etc. Numerous studies have been undertaken pertaining to water resources management but only few studies are related to planning the water environment. Recent advances in GIS Geographic Information System technology and the remarkable achievement of several operational research techniques that can be applied together with GIS have enable the state-of-art of water environmental planning to be enhanced beyond the existing practices. The combination of GIS and Multi-Criteria/Objectives Decision making MCDM/MODM methods with a special reference to the Analytic Hierarchy Process AHP technique have resolved many issues pertaining to unstructured and ill-defined data sets of water environmental planning. An attempt to integrate GIS and AHP as a Spatial Planning and Decision Support System SPDSS model for land use planning was initiated in the early 1990s. The model was then applied to study the conservation of water resources in Selangor state by using five distinctive sets of criteria namely water catchment area slope altitude land use and aquifer area.
