... Some new methods, such as radar altimetry and Interferometric Altimetry, to remotely monitor the streamflow and changes in terrestrial surface water storage are proposed. These new techniques will provide measurements that will enable a better understanding of the land surface branch of the global hydrologic cycle, will aid in the prediction of the consequences of global change, and will be useful in water resources management.

... These variations are though to be related to similar low-frequency climate variations from the Pacific and Atlantic Ocean basins. Future PDSI projections computed from the GCM estimates of precipitation and temperature, also contain significant multidecadal variations, as well as significant negative trends.

... In addition to greenhouse warming and concerns about an accelerated hydrologic cycle, several other anthropogenic factors interact with the water system to produce potentially global-scale effects. Prominent among these are widespread land cover change, urbanization, reservoir construction, irrigated agriculture, destruction of aquatic habitat, and pollution.

... We documented population dynamics and feeding ecology of greenback cutthroat trout and brook trout at 10 stream sites in the Rocky Mountains. Analysis of population, body condition, stomach content, and stable isotope data were used to determine if competition for food or predation were occurring.

... Significant quantities of freshwater are withdrawn by thermal power plants producing electricity; conversely, energy is required for drawing, transporting, treating and using water and for processing wastewater. Problems are already emerging in water and energy supplies in diverse locations and future trends in population and possibly climate are expected to exacerbate these problems.

... This knowledge, combined with information on how residents view themselves and the environment, will help public educators in California and the region craft appropriate and effective learning opportunities for specific demographic groups and the public in general.
