**2. Materials and methods**

This article is based on data from literature searches and secondary data collection. The main data on water resources were collected from the FAO global database AQUASTAT available at: https://www.fao.org/aquastat/statistics/query/index. html?lang=fr. For the case study on the Senegal River Basin, the databases of the Direction de la Gestion et de la Planification des Ressources en Eau (DGPRE) and of the Organization pour la Mise en Valeur du fleuve Sénégal (OMVS) were used. The combined approach to data collection (on dam issues) is favored here. It consisted first of all of a consultation of unpublished documents (books, reports, dissertations, *Water Resources Management and Hydraulic Infrastructures in the Senegal River Basin… DOI: http://dx.doi.org/10.5772/intechopen.105633*

theses, articles, etc.) which are of great interest for the present. This in-depth review of the literature allowed us to collect different data and information available on the impact of dams in areas where similar studies have been conducted.
