Agriculture is critical for a country’s population growth and economic expansion. In Saudi Arabia (SA), agriculture relies on groundwater, seasonal water, desalinated recycled water due to lack of surface resources, dry environment, scanty rainfall. Estimating consumption plan crop requirements (CWR) in changing environments difficult micro-level data consumption, particularly agricultural syst...

In Kurnool district, due to the hot, arid climatic conditions, proper study of crop evapotranspiration and its effect on water demand for various crops is an extremely important issue. More focus will be given design development surface irrigation systems based mostly furrow irrigation, as rainfall pattern this district was irregular in 2005. The requirement parameters optimising beneficial uti...

The following method was used to apply the topology of current study evapotranspiration ETo, net irrigation demand, schedules, and total effective rain fall different crop models: using Food Agriculture Organization's (FAO) CROPWAT 8.0 standard software CLIMWAT 2.0 tool FAO-56 Penman-Monteith approach examine variable ETo. Due high temperatures in summer with an annual mean 6.33 mm/day, topolog...

Abstract Remote sensing techniques are currently used in different fields including irrigation and water management fields. One of the important is calculation consumption (WC). can be to estimate actual evapotranspiration it also crop coefficients based on spectral reflectance vegetation indices (VIs), from a relation with normalized difference index (NDVI), which an indicator for absorption r...

Climate change is changing global weather patterns, with an increase in droughts expected to impact crop yields due water scarcity. Crops can be provided via underground pumping systems mitigate shortages. However, the energy required pump tends expensive and hazardous environment. This paper explores different sites Sudan assess requirements as first stage of developing renewable sources based...
