Modelling Future Water Demand With WEAP Model: The Case Study of Marahoué Basin in Côte d’Ivoire
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 1
Abstract
The Marahoué basin in west-central Côte d'Ivoire is a transitional zone between the Sudanese climate and the attenuated equatorial one. This duality favors agricultural and pastoral activities in relation to a population growth requiring a high water demand. Faced to this problematic, we proposed to experiment the WEAP (Water Evaluation And Planning system) model on the Marahoué basin. The objective of this study is, modelling water demand on the horizon 2040. To achieve this, several types of data were injected into the WEAP21 in this case: precipitation, runoff, groundwater, growing, breeding, industrial and demographic data. They were compilated to estimate the five-year water demands for 2010 to 2040. Base on the priorities assigned to each request, growing and breeding needs are the most important with 25.2 million cubic meters due to a high growth rate of livestock. This sector is followed by the demand for urban and rural populations' water supply, estimated at 39.5 million cubic meters in a growth scenario. Industrial demand is low because of the weak development of this sector in the basin. It remains constant with a need of 1.4 million cubic meters. According to the forecast results of the model, all trends in the different sectors will exceed their double by 2040.
