introduction evapotranspiration is one of the most important elements of hydrological cycle which is required for water resource management and design of irrigation systems. crop evapotranspiration (etc) can be measured by the lysimeter using water balance equation. it also can be estimated by multiplying reference evapotranspiration (eto) and crop coefficient (kc). considering the importance o...

Abstract Increasing population and a severe water crisis are imposing growing pressure on Iranian cropping systems to increase crop production meet the rising demand for food. Little is known about separate contribution of trends variability harvested area yield in severely drought-prone areas such as Iran. In this study we (a) quantify importance 12 most important annual crops under rainfed ir...

Simple formulas for estimating annual actual evapotranspiration (AET) based on climate data are widely used in large scale applications. Such do not have distinct compartments related to topography, soil and irrigation, this reason may be limited basins with high slopes, where runoff is the dominant water balance component, irrigated agriculture dominant. Thus, a simplistic method assessing AET...

Resorcinol-formaldehyde (RF) resin is a kind of excellent exterior-grade wood structural adhesive, which can be conveniently cold-set for various applications. In order to decrease the production cost, pyrolysis bio-oil from renewable bioresources was used to replace resorcinol to synthesize the bio-oil-resorcinol-aldehyde (BRF) resin. The effect of replacing resorcinol with bio-oil on the prop...

abstract in this research, temporal trends of reference evapotranspiration (et0) values were investigated in arid regions of iran. for this purpose, the meteorological observations collected from 11 high quality meteorological sites for a 41-year period (1965-2005) were used and statistically significant et0 trends in the monthly, seasonal and annual time basis were detected by the non-parametr...
