Within the Deschutes River basin of central Oregon, the geology, hydrology, and physiography influence geomoqhic and ecologic processes at a variety of temporal and spatial scales. Hydrologic and physiographic characteristics of the basin are related to underlying geologic materials. In the southwestern part of the basin, Quaternary volcanism and tectonism has created basin fills and covered an...

This study investigated the relationship between the hydrological response of a river basin to anticipated urbanisation and its subbasin characteristics by applying a hydrological model (HSPF) with land use scenarios generated by an urban growth model (LEAM). The hydrological model was set up and run for the Kishwaukee River basin in northeastern Illinois, USA. The results show that the subbasi...

[1] A long-standing challenge for hydrologists has been a lack of observational data on global-scale basin hydrological behavior. With observations from NASA's Gravity Recovery and Climate Experiment (GRACE) mission, hydrologists are now able to study terrestrial water storage for large river basins (>200,000 km2), with monthly time resolution. Here we provide results of a time series model of ...
