appraisal of the trend of soil infiltration rate changes in flood spreading stations of iran
flood spreading stations were constructed in iran with different objectives such as groundwater recharge and vegetation recovery. accumulation of sediment can be a major problem in flood spreading stations. according to generally accepted theories, floods and salt pollution can reduce gradually the infiltration rate. in order to investigate this issue, 13 flood spreading stations were selected ...
متن کاملinvestigation the effects of flood water spreading on infiltration trend in bushehr province
flood spreading has an effective role in the soil improvement and fertility, ground water storage, revival of vegetation and prevention of fluent sands movement. one of the main problem of flood spreading projects is the entrance of sediment to the spreading systems and sedimentation in it. sediment reduces the efficiency of the flood spreading system and after awhile lose its efficiency.the ma...
متن کاملEvaluating the effectiveness of flood spreading scheme from the perspective of marginal communities (Case study: Jajarm flood spreading)
Flood spreading schemes have been implemented in Iran to control floods, feed groundwater aquifers, improve vegetation, and increase pasture production. The proper evaluation of these projects is possible when the scheme is evaluated based on the opinions of residents and users. The purpose of this study is to evaluate the effectiveness of the Jajarm flood spreading from the neighboring village...

estimation surface soil shear strength by pedo-transfer functions and soil spatial prediction functions
abstract surface soil shear strength is an effective parameter in soil erosion and runoff modeling, and known as soil erodibility index. this study was conducted to investigate and predict soil shear strength in central zagros region using multiple linear regressions (mlr). the study site was selected in rangeland and degraded-rangeland landuse with an area of 23562 ha. based on the maps of geo...
