Rivers State as the nomenclature depicts is a state richly blessed with both surface and subsurface water. As a result of this, there is less problem of water scarcity, especially in the elite cities of the state, but so many other communities due to one reason or the other still wallow in abject water scarcity. In this survey, a total of seven (7) vertical electric soundings were carried out using Schlumberger configuration at Obibi community in Omuma local government area, Rivers State, to ascertain the location and depths to aquifer. ABEM terrameter SAS 300 was used in the survey with electrode spacing AB/2 of 150 m, thus probing to a depth of about 200 m. Geoelectric software (IPI2WIN) was utilized in the plotting, iteration and interpretation of the resistivity data obtained. From the quantitative interpretation and the lithology of the areas, five different subsurface layers were delineated with their geoelectric curve given as AK, AKQ and AKH. Aquifer in these areas is highly prolific and mostly located at an average depth of 52 m.

地下水潜力的地电评估:以尼日利亚河流州奥马马地方政府为例

术语所描述的河流州是一个拥有丰富的地表水和地下水的州。结果,水资源短缺的问题就更少了,尤其是在该州的精英城市中,但是由于一个原因或其他原因,许多其他社区仍然陷入严重的水资源短缺。在这项调查中,使用斯伦贝谢配置在Rivers State Omuma地方政府区域的Obibi社区进行了总共七(7)个垂直电测深,以确定含水层的位置和深度。ABEM地形计SAS 300用于测量,电极间距AB / 2为150 m,因此探测到约200 m的深度。在获得的电阻率数据的绘图,迭代和解释中使用了地电软件(IPI2WIN)。从区域的定量解释和岩性来看,划定了五个不同的地下层,其地电曲线分别为AK,AKQ和AKH。这些地区的含水层高度多产,大多位于52 m的平均深度。
