Abstract:

The Lobo river basin has been the subject of several studies in the water resources framework. However, with WEAP (Water Evaluation and Planning system) a new approach experiments. WEAP model was used to assess the water resources and demands of the various sectors of activity in the Lobo basin from 2020 to 2050. According to the hydrological balance from 1980 to 2011 in both subbasins of Lobo, the comp multi-annual mean precipitation is estimated at 7,495 million Cubaicmeters(MCM) for the North Lobo and assessed to 8,448 MCM for the South Lobo. The mobilized surface water at both gauges of Nibehibe and Loboville are assessed be to 389 MCM and 1,140 MCM respectively. The groundwater potential is estimated at 1.9 and 2.83 billionCubaicmeters(BCM) respectively in North and South Lobo. The overall Water demand fluctuates between 26 MCM and 39.5 MCM from 2020 to 2050 in the baseline scenario. This demand reaches 46.15 MCM and 92.2 MCM at the end of the Rice Development Project and High population Growth scenarios respectively. in 2050, unmet demand is estimated at 17.59 MCM, 24.25 MCM, and 32.78 MCM in these three scenarios respectively.
