Fluvial dynamics in riverine borders can play an important role in political relationships between countries. Rivers move and evolve under the influence of natural processes and external drivers (e.g. land use change in river catchments). The Hirmand River is an important riverine border between Iran and Afghanistan. The present study shows the evolution and lateral shifting of the Hirmand Rive...

Due to the frequent drought periods, water consumption increase, and competition of different water-using sectors, the Hirmand catchment is in a critical water status in the Sistan region. This threat has been intensified in recent years. To cope with this problem, we must pay more attention to different types of water use such as virtual water as a water saving method. The present study calcul...

one of the obstacles that has caused agricultural sector not to reach significant and expected growth is shortage of short, medium and long–term funds to finance various activities of this sector. this study aims at investigating the economic impacts of credits granted by agricultural bank on farmers on hirmand region. the statistical population of the survey included 4691 farmers of hirmand re...

due to agriculture is a risky activity and risk models is important in order to analyze the behavior of farmers, hence, in this study, the factors affecting risk-taking and risk aversion is the region grape growers. data analysis was performed by using stochastic frontier. data gathered by questionnaires at three counties of zabol, hirmand and zahak at 265 grape farmers in crop year of 2011-201...

The catchment, or catchment area, is the area associated with a segment of a drainage network. Surface runoff in a catchment flows into the associated network segment. Catchment area is commonly used for estimating watershed parameters, such as upstream drainage area, flood frequency, or surface-water flow. Hydrologic analyses require relatively accurate catchment area estimates to furnish subs...
