ABSTRACT- In recent years, intensive drought has caused a severe yield reduction in rain-fed trees. Increasing runoff of low amount rainfall can be used to provide partial water requirement of rain-fed trees. To achieve this objective, some strategies including gravel removal (G), rill construction across to slope (R) and applying of baking soda (S) and their effects on runoff, rainfall infiltr...

In their recent study, Zhou et al.1 (hereafter Z15) aim at mapping global patterns of the relative contributions of climate and landcover change on the water yield coefficient. However, implicit and not discussed assumptions on ‘typical changes’ of the considered forcing factors2,3 raise questions on the physical integrity of substantial aspects of their analysis4. In fact, we show here that ce...

For this research work, an adequate methodology was sought for the calculation of runoff coefficient with Tirado arrangement. To achieve this, first, variables that affect were identified, then model described arrangement, and as a third part coefficient, is proposed. From theory equation weighted coefficients expression Nadal manipulated, resulting in following relationship , considering arran...

The use of permeable concrete pavements can mitigate flooding in densely populated areas by serving as a functional and sustainable mechanism for surface water absorption drainage. However, it is found that the performance pavement often limited to low moderate flows capacity matrix decreases flow rate increases. Therefore, present study was developed aiming evaluate potential reduce runoff sub...

Vegetative filter strips (VFS) are an environmental management tool used to reduce sediment and pesticide transport from surface runoff. Numerical models of VFS such as the Vegetative Filter Strip Modeling System (VFSMOD-W) are capable of predicting runoff, sediment, and pesticide reduction and can be useful tools to understand the effectiveness of VFS and environmental conditions under which t...

land surface parameterization schemes are one of the most important components in gcm and nwp models. these schemes calculate the exchanges of momentum, mass and energy between land surface and the atmosphere. runoff is one of the important components in the water cycle of the land surface scheme whose parameterization is difficult because of complexity in the processes governing the runoff gen...

Abstract This paper assesses the performances of runoff (Ro) and coefficient ( α , ratio to precipitation) simulations from 23 models during historical period then projects their future changes under two emission scenarios (SSP1‐2.6 SSP5‐8.5) in Coupled Model Intercomparison Project. Compared with UNH/GRDC Ro dataset (0.82 mm day −1 ), multi‐model median (MME) 1995–2014 produces a comparable gl...
