A study was conducted to determine the water demand of wheat crops in area around Tonna Pumping Canal. It used 2017-2018 climate data need for CROPWAT. Reference crop evapotranspiration (ETo) determined using FAO Penman Monteith method. When considering crops, four stages growth were considered: early stage, development mid-maturity, and late-maturity stages. Crops planted 2017 rabi season yiel...
The performance of irrigation schemes around the world has been below expectations. assessment is an essential step towards improving agricultural water use. One primary indicators relative supply (RIS, ratio between amount delivered and crop net requirements). This study presents a worldwide analysis scheme by evaluating key attributes that influence RIS. was based on review reports scientific...
Energy intensity, Ie (kWh/m3) is the most popular indicator when characterizing energy requirements of water cycle, due to its direct and easy interpretation. In pressurized transport systems, referred an appropriate physical framework (such as a single pipeline), it assesses efficiency process. However, in complex urban networks, only provides basic notion needs system. The aim this paper defi...
