摘要

本研究比较了巴基斯坦NaiGaj和沙特阿拉伯WadiDhahban两个具有地下水潜力(GWR)的研究区域。研究的主要目的是借助现代技术确定支持地下水可用性的不同参数,如植被、斜坡性质、雨水沟(RWR)、气候数据和土地覆盖面积。巴基斯坦和沙特阿拉伯属于干旱或半干旱地区。两个研究区域的地形几乎相同,没有发现地下水和河水。种植者用来自不同排水渠(巴基斯坦)的盐水和来自高地的雨水沟来灌溉土地。在巴基斯坦信德省的Khirthar山的斜坡上发现了一条61公里宽,326公里长的带,这条带是雨影区。同样,WadiDhahban具有相同的地理特征,位于红海海岸带附近,数十个rwr在海中呈现和颤抖。利用RS和GIS软件设计了两个研究区地下水潜势图。地理信息系统和遥感技术在绘制地下水水质和水量以进行评估和监测方面具有重要作用。从地图上可以看出,这两个地区都有地下水潜力。NaiGaj的地下水势为30.3%,WadiDhahban的地下水势为15.8%。

Conservation of Groundwater Resources in Arid Lands: A comparative study of NaiGaj Pakistan and WadiDhahban Saudi Arabia
This research was conducted to compare the two research areas NaiGaj, Pakistan and WadiDhahban, Saudi Arabia having Ground Water Potential (GWR). The main objectives of the research was to determine the different parameters that support the ground water availability such as vegetation, nature of slope, Rain Water Rills(RWR), climatic data and land cover area with help of modern techniques. Pakistan and Saudi Arabia emanates under as Arid or Semi-Arid category of land. Both research area have almost same topography, where ground and river water is not found. Growers irrigate land by saline water of different drain canals (in Pakistan) and Rain Water Rills coming from the uplands. A 61 km wide and 326 km long belt is found in slope of Khirthar Mountain in Sindh, Pakistan, this belt is rain shadowarea. Similarly, WadiDhahban has same geographical features, located near the coastal belt of RedSea, where dozens of RWRs are presents and trembled in the Sea.The maps of groundwater potential of both study areas were designed with the help of RS and GIS software.GIS and RS havesignificant role in mapping of ground-water quality and quantity for assessment and monitoring purposes.It was observed through the maps that both areas have ground water potential. Furthermore, the results indicated that NaiGaj has 30.3 % ground water potential and WadiDhahban has 15.8% ground water potential.
