Increasing of population in the world caused overusing natural resources and land destruction. Salinization and sodification are two effects of land destruction. Leaching of soil soluble salts is the most appropriate method to emend and reclaim saline and sodic soils. In this study, Examination of different leaching methods of saline from sodic soils has been evaluated in Veis Area in Khoozesta...

In regions like south of “ khouzestan” that water table are high, under the effect of water rise moving through capillary fringe and its vaporize,  the salts move to soil surface and cause salin or salin and sodic soils. Leaching assign as one of those adjustment soils methods. In order to investigate the leaching process and draw the curves of desalinization and dealkalization in region of Dar...

[1] This work quantifies and explains the direct physical effects of slope angle on infiltration and runoff generation by extending the Green-Ampt equation onto sloping surfaces. A new extended solution using identical precipitation hydrographs was compared to the original formulation and then used to calculate the infiltration and runoff generation for different slope angles but for identical ...

Water redistribution has a profound influence on dryland ecosystem function. This hydrological function is largely regulated by ecosystem engineers including biological soil crusts (biocrusts) which produce run-off, and burrowing animals, such as the greater bilby, whose pits capture water. We estimated the relative importance of these two ecosystem engineers in determining infiltration rates i...

alternate of the usurped property is a compensation paid to the owner after unavailability of usurped property. the iranian civil code, following the islamic scholars' famous view, has principally accepted the payment of this compensation but is silent as far as duties and rights of owner and usurper are concerned; hence the judge's obligation to refer to valid verdicts (fatawa) in this regard....
