ABSTRACT
In this study, Water Evaluation and Planning (WEAP) computer based water balance model was constructed and calibrated for the water Catchment at Benin City, Edo State "Nigeria using scenario approach in Water Evaluation and Planning Software (WEAP) for the period 2010 to 2060 and utilized to investigate the impacts of possible future demographic or policy changes on water demands on the catchment. Fifteen hypothetical scenarios representing plausible demographic changes, policies, population growth, water use rates, climate changes and cropping patterns were simulated. The model simulations show that the combined scenario of increase in population growth (IPGR) and increase in water use (IWU) produced the largest water demand for domestic and …show more content…

Developing too early can cause water utilities to lose money on unused facilities or developing too late risks economic and social impacts of water shortages arising. It is important that decisions making be accurate and transparent to stakeholders (public and decision makers) to this end water utilities are seeking better tools to guide and incorporate significant uncertainties. Utilities may be able to better prepare themselves for uncertainties associated with climate change and other planning elements using Integrated Water Resources Management (IWRM) Decision support System supporting tools such as WEAP.
3.1. Methodology
The method adopted for water demand assessment for Benin City is the Traditional scenario approach (Means, et. Al. 2010), this was achieved by first carrying out Hydrological modelling of Benin City catchment to determine available water supply and Water demand and secondly Scenario analysis to investigate possible effect of changes on water demand on water supply and demand balance.
The hydrological modeling involved the use of WEAP software in representing Benin
