This thesis is concerned with simulating two forms of energy retrieval.
Standard computer programs are routinely used to simulate
such energy systems. However, the accuracy of these simulations is
not well documented. The main objective of the work presented here is
to evaluate the validity of this type of simulation...
To maximize the utility of research to decisionmaking, especially given limited financial resources, scientists must set priorities for their efforts.
We present a list of the top 40 high-priority, multidisciplinary research questions directed toward informing some of the most important current
and future decisions about management of species, communities, and...
Analyses of long-term records at 35 headwater basins in the United States and Canada indicate that climate change effects on streamflow are not as clear as might be expected, perhaps because of ecosystem processes and human influences. Evapotranspiration was higher than was predicted by temperature in water-surplus ecosystems and lower...
