GIS AS A DECISION SUPPORT SYSTEM FOR SITING WATER HARVESTING PONDS IN THE BASALT AQUIFER/NE JORDAN

Abstract

Water harvesting is a must and not an option for Jordan in the near future. The available water resources are limited and barely satisfy the current growing demands. In the basalt aquifer/NE of Jordan, there is a possibility to construct water harvesting ponds to assist the livestock owners in villages and towns in watering their livestock which will ease the pressure on the existing water resources. This research was based on the use of GIS techniques to select the optimum sites for water harvesting ponds within the basalt aquifer. Buffering, Union and arithmetic operations in GIS were all used in analysing the data based on different socio-economic and physical criteria. The outcomes of the GIS analysis resulted in selecting 72 suitable sites within the study area. These sites could be used as a guideline to the decision makers in Jordan when they decided to establish a water harvesting pond in the area. This will save time and money which could be directed to the construction of the actual water harvesting ponds.
