Analysis of meteorological water availability and water demand in Cemoro River section area

About 69% of Cemoro River Section Area is dryland agricultures. Rain is the main source of irrigation for the dryland agricultures, but during dry season farmers use Cemoro River water for irrigation which is directly flowed using a water pump. The potential of water resources in Cemoro River Sectio...

Description
Summary:About 69% of Cemoro River Section Area is dryland agricultures. Rain is the main source of irrigation for the dryland agricultures, but during dry season farmers use Cemoro River water for irrigation which is directly flowed using a water pump. The potential of water resources in Cemoro River Section Area is very important and determines agricultural products. The aim of this study is to analyze meteorological water availability and water demand in Cemoro River Section Area. Thornthwaite Mather method is used to calculate meteorological water, while the total water demand are calculated based on the domestic water demand, livestock water demand, and agricultural water demand. The result shows that discharge from 60% rain probability could meet total water demand stated as a surplus, but discharge from 80% rain probability could not meet total water demand and classified as deficit.
