Using electrical profilings, soundings and resistivity tomography for groundwater reservoirs exploration in cristalline area of Man (West Côte d’Ivoire)

In order to collect electrical resistivity tomography data, an IRIS Instrument Syscal R1 Plus resistivity-meter was used in conjunction with a multicore-based connection device capable of concurrently connecting up to 32 electrodes spaced 5 m apart. As a result, the overall length of each ERT profile was 155 m. Electrical Resistivity Tomography (ERT) survey used a Wenner alpha array configuration for electrical resistivity data acquisition.
The application of the Electrical resistivity tomography (ERT) Method, in conjunction with the BERT python-based inversion approach, leads to the development of a dependable methodology for fault identification.and aquifer characterization in a cristalline rock area of Man (Côte d'Ivoire).

为收集电电阻率层析成像数据，本研究采用了 IRIS 仪器系统 SCAL R1 Plus 电阻率计，并配合一种基于多芯连接的设备，能够同时连接间距为 5 米的最多 32 个电极。因此，每个电电阻率层析成像剖面（ERT）的总长度达到了 155 米。在电电阻率层析成像（ERT）调查中，采用了 Wenner alpha 数组配置进行电电阻率数据的采集。将电电阻率层析成像（ERT）方法与基于 BERT Python 的反演方法相结合，在非洲科特迪瓦的曼地区（Man）的结晶岩石区域，开发出了一种可靠的故障识别和含水层特征描述的方法。
