Quantitation and evaluation of infiltration models are used in soil conservation, irrigation systems, hydrology investigations, watershed and watershed management systems. The purpose of this study was to estimate the infiltration by using statistical and experimental various models in two soils of plowed and without plowed in Haraz Technology and Development center paddy fields of Mazandaran p...

Effective soil conservation requires a framework modelling that can evaluate erosion for different land-use scenarios. The USLE model was used to predict the reaction of appropriate land-cover/land-use scenarios in reducing sediment yield at the upland watershed of Yamchi Dam (474 km2), West Ardabil Province, Iran. Beside existing scenario, seven other land-use management scenarios were determi...

Prioritization of sub-watersheds is very important and necessary in order to implement soil and water conservation practices. This study has prioritized 13 sub-watersheds based on morphometric and land use characteristics using RS and GIS techniques in Haraz watershed to identify erosion-prone sub-watersheds. Morphometric characteristics including bifurcation ratio, drainage density, stream fre...

Soil erosion, especially water erosion, threatens the installations, water resources and also human life. The first stage of water erosion is the splash erosion that it requires to control in the primary stages. On the other hand, the application of soil conditioners is one of the approaches that it provide the conservation possibility of soil surface against water erosion, especially erosion f...

A suitable instrument capable of inserting mulch into soil is needed to improve soil water holding capacity. The goal of this research is to design and manufacture an instrument with a blade and mechanism that can insert rice mulch into the soil. All the parameters in sub-soiling operation were taken into account, and the technique presented can be recommended as a special method of injecting r...
