Assessing Experimental and Intelligent Models in Estimating Reference Evapotranspiration
Introduction: As the most important element in the hydrologic cycle which depends on climate variables such as near-ground wind speed, air temperature, solar radiation, and relative humidity, reference evapotranspiration (ET0) is normally computed through a variety of methods, each of which requires different and in some cases extensive data that are unavailable in many circumstances, especial...
متن کاملModelling of Crop Reference Evapotranspiration: A Review
Efficient irrigation water management requires a good quantification of evapotranspiration. The precise estimation of water requirement of crop is very important factor in the application of irrigation design and scheduling. Water relation model are essential component of all crop model because of critical role of water status has in determining growth, productivity and produce quality. Irrigat...
متن کاملEstimating Riparian and Agricultural Actual Evapotranspiration by Reference Evapotranspiration and MODIS Enhanced Vegetation Index
Dryland river basins frequently support both irrigated agriculture and riparian vegetation and remote sensing methods are needed to monitor water use by both crops and natural vegetation in irrigation districts. We developed an algorithm for estimating actual evapotranspiration (ETa) based on the Enhanced Vegetation Index (EVI) from the Moderate Resolution Imaging Spectrometer (MODIS) sensor on...
متن کاملUsing Modified Bellani Plate Evapotranspiration Gauges to Estimate Short Canopy Reference Evapotranspiration
Modified Bellani plate atmometer has been offered as an alternative and simpler technique to combination-based equations to estimate evapotranspiration ~ET! rate from green grass surface. However, there is a lack of information on its’ accuracy in humid climates. The evaporation rate sEAd from one type of atmometer marketed under the brand name ETgage® ~or ETG! with a Number 30 green canvas cov...
متن کاملScaling Potential Evapotranspiration with Greenhouse Warming
3 Potential evapotranspiration (PET) is a supply-independent measure of the evaporative de4 mand of a terrestrial climate, of basic importance in climatology, hydrology, and agriculture. 5 Future increases in PET from greenhouse warming are often cited as key drivers of global 6 trends toward drought and aridity. The present work computes recent and business-as-usual7 future Penman-Monteith PET...
