متن کاملEffect of soil erosion on available phosphorus losses in a Hyrcanian watershed
One of the most important main environmental problems is soil erosion and its affects. Eutrophication, low oxygen levels and `high nutrient (nitrogen and phosphorus) concentrations in reservoirs, channel and other water courses, is a common water pollution feature. Phosphorus (P) is one of the major plant nutrients and also the major nutrients controlling eutrophication of surface water. The ai...

Introduction Water erosion is one of the most important factors in land degradation in large parts of Iran destroying fertile soils and agricultural land. The impact of soil erosion and related sediments decreases significantly water quality and reservoir capacity. Especially in semiarid areas like in the Menderjan watershed in the west Isfahan province sheet and rill erosion contributes to th...
متن کاملMonitoring Land Cover Changes of Forests and Coastal Areas of Northern Iran (1988-2010): A Remote Sensing Approach
Caspian Sea coastline in the Mazandaran province has been altered as a result of activities of developers attracted to aesthetic and coastal recreational aspects of forest ecosystems. Advances in GIS and RS techniques, has made it possible to study the coastal areas for better management. Hence, the present study was undertaken to determine land cover changes via applying cross classificat...
