Introduction: Many impact basins on the Moon are filled with extensive mare basalts [1]. This obscures a) the primary structure of fresh basin interiors, including the nature and distribution of impact melts, and b) the nature of the early stages of the filling of basins with mare basalts. In contrast, the interior of the Orientale basin, the youngest and most well-preserved large basin on the ...

designing effective strategies for sediment management and control is closely related to identification of sediment sources in a drainage basin. one of the methods for investigating sediment sources is using magnetic tracers for erosion and sediment yield studies. sediment source identification using magnetic characteristics is a simple, inexpensive, quick and non-destructive method having appl...

abstract in this research the thermal stratification of the water in the torogh dam basin and the resulted changes in its quality with respect to temperature, salinity and dissolved oxygen was investigated using the dynamic reservoir simulation model. the results indicated that in wet years such as 1998, when the average annual precipitation and the resulted inflows to the basin is higher than ...

although typically small in terms of their spatial footprint, landslide hazards are relativelyfrequent in northern iran. we assess landslide susceptibility for the nearly 20.000 km2 large study area of the urmia lake basin which is dominated by agricultural land use but includes the major settlements areas of the east azerbaijan province, iran. landslide factors are established in form of gis d...

sub basin prioritization is one of the integrated watershed management and sustainable development strategies. to protect natural resources, through marking zones of potential damage in small areas for is a primary need sustainable development. degradation potential zones project for watershed protection measures is not cost-effective economically. so this is a prerequisite for sub basin priori...
