Water is one of the most imperative needs and used for innumerable purpose. The needs of groundwater exploration have being increased due to the radical climatic changes, for continually increased population growth and a change of human lifestyle. GIS and AHP of multicriteria decision making are the most effective, applicable and logical approaches to delineate the groundwater potential zones in upper parts of Chemoga watershed. GIS and AHP are a 7 computer-based systems used to handle, store, manipulate, analyze and present geospatial data to resolve several complicated problems in the environment. Hence, the groundwater potential zone is delineated by overlaying the weights of ten influencing factors (lineament density, rainfall, geomorphology, Lithology, slope, drainage density, roughness, land use/land cover, depth to groundwater level and elevation) in ArcGIS platform under spatial analysis tool. All those influencing factors are selected on the bases of their contribution for the ground water recharge. Based on the findings of weighted overlay analysis, 11.1, 18.2, 47.1, 15.4 and 8.2% of the region depicted very good, good, moderately good, poor, very poor groundwater potential zones, respectively. The investigated groundwater potential sites have validated by seven existed borehole data and hence the study verified their close relationships. Out of seven boreholes, about 7–4 and 3–1 were found under very good to good and poor to very poor groundwater potential zones, respectively.

水是最迫切的需求之一，有着无数的用途。由于气候的剧烈变化、人口的不断增长和人类生活方式的改变，地下水勘探的需求不断增加。多准则决策的GIS和AHP是划定Chemoga流域上部地下水潜力区的最有效、最适用和最合理的方法。 GIS 和 AHP 是 7 个基于计算机的系统，用于处理、存储、操作、分析和呈现地理空间数据，以解决环境中的一些复杂问题。因此，在ArcGIS平台下，通过叠加10个影响因素（线状密度、降雨量、地貌、岩性、坡度、排水密度、粗糙度、土地利用/土地覆盖、地下水位深度和高程）的权重，圈定地下水潜力区。空间分析工具。所有这些影响因素都是根据其对地下水补给的贡献来选择的。根据加权叠加分析结果，11.1%、18.2%、47.1%、15.4%和8.2%的区域分别属于地下水潜力非常好、良好、一般、差和极差的区域。调查的地下水潜力地点已通过七个现有钻孔数据进行了验证，因此本研究验证了它们的密切关系。在 7 个钻孔中，分别发现约 7-4 个和 3-1 个位于非常好到好和差到非常差的地下水潜力区域。
