The Ab-Barik watershed in Bam is a part of Lut desert basin. It is like all other desert areas which has erosion problems caused by wind erosion, sand and soil storms. The result of these sand storms appears as continuous and isolated sand hills. In this paper it was attempted to identify direction and source of harvest points by using sedimentological methods. This was accomplished by step by ...

if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...

Soil erosion is an inevitable phenomenon that additive erosion caused Soil degradation. Additive Soil erosion is one of the major obstacles to achieve the development of agriculture and natural resources. Thus, knowledge of the status and trends of soil erosion and sediment production in the watersheds is one of the most important tools for planning and decision-making. Models are the most popu...

Improper management of watershed land utilization has many ill effects on the available resources. Land use optimization is one of the proper strategies to achieve sustainable development and to reduce resource dissipation. Focusing on Brimvand watershed in Kermanshah province which comprises an area of 9572 ha, the present study was conducted to find out the most suitable land allocation to di...

drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

Soil  erosion  as a  one  of  the  biggest  environmental  problems  worldwide, is threatening  both ecosystem health and  food security. This case study conducted in Khamsan paired watersheds aimed to compare runoff volume and sediment yields from 51 natural rainfall events on 18 USLE’s standard plots, where they had installed on the different conditions in the term of enclosure and aspect. Fa...
