Monthly Rainfall Data at Station Bobo Dioulasso and Flowrate Data Nwokuy Sub-Basin, Mouhoun Watershed, Burkina Faso, 1983-2013

Monthly flowrate calculation data for the Nwokuy Sub-Basin, Mouhoun Watershed, made for study: "Integrated Water Resources Management in Burkina-Faso through numerical modeling: Case study of the Mouhoun Basin" Population explosion, random changes in weather conditions and human actions are all factors that influence the water resources availability. The objective of the study is to develop a strategy for sustainable water management in the Nwokuy sub-basin by assessing the availability and sustainability of water resources use in this basin through hydrological modelling. Two models were used, namely the GR2M model and the WEAP model. The GR2M (the hydrological model) was applied to fill the gaps in the historical flow data set obtained at the Nwokuy station. With the WEAP model, four scenarios were created and projections were made to the year 2100. Application of the WEAP model scenarios shows that in both deficit years and wet years, water demands for irrigation and domestic use are covered 100% for the first three scenarios. However, anthropogenic action such as the construction of the Samendeni dam could, in the future, lead to cases of unmet demand. The Samendeni flow scenario shows that the water deficit for irrigation could start in 2080 and the water deficit for domestic needs in 2090.
