introduction: the infiltration process is one of the most important components of the hydrologic cycle. quantifying the infiltration water into soil is of great importance in watershed management. prediction of flooding, erosion and pollutant transport all depends on the rate of runoff which is directly affected by the rate of infiltration. quantification of infiltration water into soil is also...

study of soil quality indicators were considered as a useful method in the land use management. changing the land use affect soil hydrological processes such as water infiltration process. spatial variation of water infiltration in soil plays a very important role in hydrologic processes. variability of this process is affected by the inherent and non-inherent characters of the lands. in order ...

ABSTRACT- To study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in Badjgah, Fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). In each pl...

infiltration is a complex process that changed by initial moisture and water head on the soil surface. the main objective of this study was to estimate the coefficients of infiltration equations, kostiakov-lewis, philip and horton, and evaluate the sensitivity of these equations and their coefficients under various initial conditions (initial moisture soil) and boundary (water head on soil surf...

runoff production process is a key hydrological component illustrating watersheds health. water infiltration in soil is also one of the determinant factors on runoff generation for which many techniques were used to improve it. however, the role of microorganisms for the improvement of water infiltration in soil has been less considered. the present study therefore tried to investigate the effe...

plant cover is one of the most important factors affecting infiltration rate of water into the soil and decreasing runoff. distribution of plants in arid and semi-arid areas is almost patchy and form different patterns. one of the fascinating patterns is ring-shaped growth pattern. ring patterns of varying size are formed by clonally reproducing grasses, sedges and even shrubs growing in resour...
