This article investigates the hydrological response and ecological flow in diversion area from Hanjiang River to Weihe River. Quantifies impact of inter-basin project on hydro-ecological environment downstream river. MIKE BASIN is initially utilized this research create multi-year reservoir operating model Sanhekou Reservoir. Then Indicators Hydrologic Alteration (IHA) Range Variability Approac...
The windings of rivers have long fascinated their human observers. For example, Aboriginal legend explains the sinuous pattern of the modern Finke River (Fig. 1) as the creation of the immense and powerful Rainbow Serpent as he emerged during the Dreamtime from deep waterholes. Recently in PNAS (1), a new theory for the general origin of such sinuous flow patterns was published, which follows f...
The water quality of six important rivers in Haihe River Basin, including Yongding River, Luanhe North Canal, Daqing South Canal and Chaobai was evaluated. influence point source non-point on analyzed. causes environmental pollution the major were preliminarily revealed. results show that is good, impact discharge body small. Other are affected by different degrees pollution. Based analysis res...
Total suspended sediments and the total dissolved solids (TDS) from three river gaging stations, near Delaware Water Gap, Riegelsville and Trenton on the Delaware River measured by the USGS were used to estimate the physical erosion, chemical weathering and total denudation rates of the Delaware River Basin. The denudation rates are 28 and 128 tons/km 2 /yr for the upper stream and downstream s...
Climate variation and human activities are commonly recognized as two major factors affecting basin hydrology. However, quantifying their individual effect on runoff is challenging. In this study, long-term (1960–2009) river discharge and weather data in the Songhua River Basin (SRB, 556,800 km2), Northeast China, were gathered to separate the impacts of climate variation and human activities o...
This paper employs an economic-engineering optimization model to explore water supply options for environmental restoration of the Colorado River Delta, Mexico. Potential water sources include reductions in local agricultural and urban water use through water markets, wastewater reuse, and additional Colorado River flows from the United States. For these alternatives, the optimization model est...
