GOD Data in Garoua

Field measurements of static water levels of dug wells were done using a Solinst meter. The surface elevation data was taken from digital elevation model (DEM). Overlying strata was gotten from lithological sections of some representative productive wells in Garoua. Seasonal field measurements of groundwater and air temperature, pH, TDS of 164 dug wells using Trimeter groundwater and air temperature variation together with geology were used to infer the aquifer type. This study which assesses the vulnerability of the aquifer in Garoua with seasons will serve as a blueprint and help to raise awareness among the population on behavioral change in terms of integrated management groundwater resources but will also help to preserve natural resources. Data from this study will enable stakeholders to take necessary actions in preventing groundwater resources to pollution.本研究采用Solinst水位计对挖掘式水井（dug wells）的静态水位开展实地测量。地表高程数据取自数字高程模型（Digital Elevation Model, DEM）。上覆岩层数据取自加鲁阿（Garoua）地区部分代表性生产井的岩性剖面。针对164口挖掘式水井，本研究借助Trimeter设备完成了地下水、气温、pH值及总溶解固体（Total Dissolved Solids, TDS）的季节性实地监测，并结合气温变化与地质资料推断含水层类型。本研究针对加鲁阿地区含水层的季节变化脆弱性开展评估，既可作为区域地下水综合管理的参考蓝本，助力民众转变行为观念以提升地下水资源保护意识，同时也能为自然资源保护提供支持。本研究的数据将为利益相关方采取必要措施防范地下水资源遭受污染提供决策依据。
