the response of karoun basin in lumped and semi-distributed simulation were compared. also, the flood intensity of the sub-basins and the effects of physical parameters on flood hydrograph have been investigated. results demonstrated that there was no significant difference between the characteristics of flood hydrograph in lumped and semi-distributed simulation. also, results showed that the f...

The availability of water in Chile has shown signs decline recent decades. This is problematic because Chile’s economy depends on mining, forestry, and agricultural activities, all limited by the resources. In this study, daily, monthly annual flows 31 basins located arid–semiarid zones (29°12′ S–33°58′ S) humid–subhumid (34°43′ S–38°30′ were evaluated using Mann–Kendall trend test quantile–Ken...

Automated classification of satellite images is a challenging task that enables the use remote sensing data for environmental modeling Earth’s landscapes. In this document, we implement GRASS GIS-based framework discriminating land cover types to identify changes in endorheic basins ephemeral salt lakes Chott Melrhir and Merouane, Algeria; employ embedded algorithms image processing. This study...

arid and semi-arid regions of the world are confronted with limited water resources. a large part of iran is arid and semi-arid and rainfall in arid and semi-arid regions is typically meager, irregular and highly variable. this irregularity affects the hydrological cycle and water resources. investigating the hydrology of the arid and semi arid regions is essential to know this environment and ...

Climate change (CC) is likely to have a negative effect on water balance components thereby increasing global scarcity. These effects, particularly in arid and semi-arid areas, not been fully understood, part because green was adequately represented the relevant assessments. This study analyzes spatiotemporal variations of blue resources under baseline future climate conditions by applying Soil...

Reservoirs overflow during flood season because of sedimentation cycles, which severely affects their effectiveness. Siltation is a major problem in dams constructed waterways arid and semi-arid areas. Therefore, the reservoirs wadis lose capacity due to sedimentation. This study determines an optimal design trapping basin on steep slope areas for Wadi Bishah Asir region southwestern Saudi Arab...

The role of water quality, particularly its impact on health, environment and wider well-being, are rarely acknowledged in the water–energy–food (WEF) nexus. Here we demonstrate necessity to include quality within dimension WEF nexus address complex multi-disciplinary challenges facing humanity. Firstly, energy food dimensions vice versa at multiple scales, from households cities, regions trans...

many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. on sloping basins, however, few such studies have been performed so that the issue requires more investigation. a significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. this study was carried ...
