This document summarizes a research project using remote sensing and terrain modeling to identify suitable zones for manual drilling in Senegal and Guinea. The research is a collaboration between University Milano Bicocca, University Cheik Anta Diop, SNAPE, and UNICEF. The objective is to integrate hydrogeological data with remote sensing data to characterize shallow aquifers and identify zones suitable for manual drilling. The study areas are in Senegal's Louga-Kebemer region and Guinea's Kankan and Faranah regions. Expected outputs include validated methods to infer shallow hydrogeology and suitability for manual drilling from indirect data, as well as maps of suitable zones. Key factors for success
