Calibration of Rainfall-Rainwater Capturing Mechanism Using Integrated Water Management Model (IWMm) in Auchi, Nigeria
Journal Title: Scientia Agriculturae - Year 2015, Vol 12, Issue 2
Abstract
Accessibility of safe drinking water is a serious constraint in Auchi and its environs. This region mainly depends on rainwater and groundwater exploration. Sensitivity simulation analysis using structured IWRM model shows that there is a strong relationship with the rainfall, rainwater capture and roof plan size (RPS). Average annual rainfall of 1430 mm and 1600 mm simulated with varying roof plan surfaces (RPS) of 100 m2, 250 m2; 500 m2; 1000 m2; and 2000 m2 produced RWHI index of 0.1, 0.24, 0.47, 0.94 and 1.89 respectively. Simulation output indicated that an average of 5,300m3 /day of rainwater were harvestable and this value of water could only meet daily water demand of 40,769 people. The output of statistics metrics shows a perfect match (RPS) and harvested rainwater as R2= 0.78; 0.77 and r.m.s of 0.100 respectively. The overall result shows that if the potential of rainwater harvest is fully-harnessed, that will reduce the water stress and constrain in Auchi.
