This work explores the spatial distribution of monsoonal flooded areas using ENVISAT C-band Advanced Synthetic Aperture Radar (ASAR) in the semi-arid region of N. Gujarat, India. The amplitude component of SAR Single Look Complex (SLC) images has been used to estimate the extent of surface and near-surface water dynamics using the mean amplitude (MA) of monsoonal (July to September) and post-mo...

Relationships between surface waters and groundwaters at basin scale are rarely investigated but have important implications for water resource development management. Here, we integrate evidence from geochemical tracers piezometry to advance the understanding of regional-scale, groundwater–surface interactions in River Awash Basin Ethiopia. Hydrological characteristics consistent with those ob...

Sustaining irrigated agriculture to meet food production needs while maintaining aquatic ecosystems is at the heart of many policy debates in various parts of the world, especially in arid and semi-arid areas. Researchers and practitioners are increasingly calling for integrated approaches, and policy-makers are progressively supporting the inclusion of ecological and social aspects in water ma...

In studying the hydro-ecological conditions in northwestern Sichuan of southwestern China, an area at the edge of the Qinghai-Tibet Plateau, stream waters were extensively sampled and analyzed for the stable hydrogen and oxygen isotope ratios (  H and  18 O) which are often excellent indicators for a water body genesis and evolvement. The heavy isotopes of hydrogen and oxygen were found to b...

Water resources provided by alpine glaciers are an important pillar for people in the arid regions of west China. In this study, the Hydrologiska Byrans Vattenavdelning (HBV) light model was applied to simulate glacier mass balance (GMB) and runoff in the Koxkar River Basin (KRB) on the south slope of Mount Tumur, in the western Tianshan Mountains. Daily temperature and precipitation were calcu...

7 Heihe River Basin is located in the arid inland area of northwest China and is facing 8 serious water shortage problems. Since irrigation is the largest water consumer in the 9 middle reaches of the Basin, it is crucial to study the crop yields and water 10 consumption in order to improve the agricultural water productivity and to support 11 sustainable economic development in this region. Ba...

An approach is proposed for evaluating water management strategies in river basins. Reasonably large sets of criterions and objectives are manipulated during a three-phase process by appropriate shrinking and enlarging related decision hierarchies. In the first phase an unrestricted set of management interests are grouped into (1) long-term, and (2) middleand short-term decision context by crea...

The Heihe River Basin (HRB) is the second largest inland river basin in arid Northwest China. The expanding agricultural irrigation, growing industrialization, and increasing urban development in the middle reach have depleted much of the river flow to the lower reach, degrading the corresponding ecosystems. Since the enactment of the State Council of China's new HRB water allocation policy in ...

Understanding the variations of streamflow of rivers is an important prerequisite for designing hydraulic structures as well as managing surface water resources in basins. An overview of the impact of climate change on the streamflow in the Hablehroud River, the main river of a semi-arid basin in north-central Iran, is provided. Using the LARS-WG statistical downscaling model, the outputs of Ha...
