    <description descriptionType="Abstract">&lt;p&gt;As water is vital for life, analysis of water supply and demand in the basin is necessary.&lt;br&gt;
This will enable to formulate water allocation strategies and allocation principles for&lt;br&gt;
present and future planning. In this paper assessment of water supply and demands was&lt;br&gt;
modeled using the Water Evaluation and Planning model. The parameter Estimation Tool&lt;br&gt;
was used to calibrate and validate the model. Future water demand was estimated using&lt;br&gt;
four different scenarios namely Scenario-I: high population growth, Scenario-II: Dangur&lt;br&gt;
hydropower, Scenario-III: Expansion of irrigation activities and Industries in Beles&lt;br&gt;
basin, and Scenario-IV: combination of scenario-I, scenario-II and scenario-III&lt;br&gt;
Simultaneously. According to the result obtained from the model, the total estimated&lt;br&gt;
mean annual surface runoff that leaves the basin is 5858.6 MCM, the estimated mean&lt;br&gt;
annual actual evapotranspiration is 10017.13 MCM, the estimated mean annual&lt;br&gt;
precipitation is 17525.33 MCM, mean annual interflow is 962.37 MCM, mean annual&lt;br&gt;
Base flow is 480.82 MCM, and mean annual flow to groundwater is 206.40 MCM. Total&lt;br&gt;
available annual streamflow including the Tana-Beles hydropower scheme is 10.03&lt;br&gt;
BCM.&lt;/p&gt;</description>
