The water of the Colorado River of the southwestern United States (U.S.) is presently used beyond its reliable supply, and the flow of this river is forecast to decrease significantly due to climate change. A recent interim report of the Colorado River Basin Water Supply and Demand Study is the first acknowledgment of these facts by U.S. federal water managers. In light of this new stance, we e...

In recent years, the population size and scale of the Shiyang River Basin unceasingly expanding lead to a series of ecological environment: surface water reducing, land desertification and Ground water levels fall, etc. Research evolution characteristics of population distribution and migration growth of Shiyang River Basin contribute to river water resources and the industrial development of t...

27 We investigate the interannual variability over 2003-2007 of different hydrological parameters in 28 the Amazon river basin: vertically-integrated water storage from the GRACE space gravimetry 29 mission, surface water level over the Amazon River and its tributaries from in situ gauges, and 30 precipitation. We analyze the spatio-temporal evolution of total water storage from GRACE and 31 in...

Based on the combined use of satellite remote sensing and geographical information systems(GIS), as well as field investigation, the land-use change dynamics and the interaction between these changes are analyzed in the Zuli River Basin located in semi-arid Loess Plateau China during the period of 1987-2005, which with typical farming-pastoral region feature of northern China. The land-use chan...

[1] Intensification of the Arctic hydrologic cycle and permafrost melt is expected as concentrations of atmospheric greenhouse gases increase. Quantifying hydrologic cycle change is difficult in remote northern regions; however, monitoring the stable isotopic composition of water runoff from Arctic rivers provides a means to investigate integrated basin-scale changes. We measured river water an...

1. River management involves satisfying societal preferences alongside environmental needs for a healthy river ecosystem. Environmental flows is a discipline that aims to define streamflow requirements that achieve desired social and ecological conditions in rivers. 2. The ecological limits of hydrologic alteration (ELOHA) framework takes a regional approach towards assessing relationships betw...
