Possible Climate Change and Its Impact on Snowmelt and Water Supply in California
Global climate modelers are forecasting relatively large future climate change, with warming of 2 to 5?C. These changes, if they do occur, would have major impacts on California's...
Large Floods and Climate Change in the Southwestern United States
Floods can have a tremendous impact on water resources but their properties may fluctuate at frequencies that defy recognition in short-term instrumented records. Paleoflood deposits provide...
Western Surface Climate and Streamflow and the El Nino/Southern Oscillation
Climate variability has direct social and economic impacts the most direct of which occur through the hydrologic cylce. Of primary concern to society are the hydrologic extremes of floods...
Complex Geomorphic Response to Minor Climate Changes, San Diego County, CA
Precipitation in San Diego County, California over the past several hundred years has been characterized by excursions between periods of relatively low precipitation having durations...
Watershed Planning and Analysis in Action
This proceedings consists of papers presented at the 1990 Watershed Management Symposium held in Durango, Colorado from July 9-14, 1990. These papers present both research performed in...
Simulated Effects of Climatic Change on Runoff and Drought in the Delaware River Basin
Various projection of climatic change were applied to watershed models of the Delaware River basin. Simulations indicate that a warming could reduce annual runoff by as much as 25 percent...
Great Lakes Waters: Too Little or Too Much?
Water supplies in the Great Lakes Basin, the world's largest fresh water supply, are more than adequate to meet current and projected needs. However, supplies could become...
Role of State Department in Environmental Issues
The Department of State plays a key role in resolving international environmental issues. This paper describes how the Department is organized to deal with environmental concerns, discusses...
Global Climate Change?Implications for Large Water Resource Systems
Prospects of global climatic change resulting from the greenhouse effect are causing increasing concern. Predicted increases in average global temperatures are likely to be accompanied...
Issues of Detectability of Climate Change Impacts on the Runoff of a Southeastern River Basin
Can we detect and predict changes in hydrology caused by climate changes? Assuming credible predictions of climate change, can we predict corresponding hydrologic effects? Are uncertainties...
Climate Change Effects on Great Lakes Levels
The Great Lakes Environmental Research Laboratory has developed conceptual models for simulating moisture storages in and runoff from the 121 watersheds draining into the Laurentian Great...
Climate Change and U.S. Water Resources: Results from a Study by the American Association for Advancement of Science
The time horizon of the changes that might occur is similar to the time required for planning, approval, funding, construction and economic life of such major water facilities as dams,...
Change Orders & Claims?An Owner's Perspective
Generally, the changes come before the claims. The owner wants to know why a change is needed, how much it will cost, and why the need for it was only just discovered. More money spent...

Marine Mammal Management in Alaska: Problems and Potential
Alaska's interest and intent in applying for management of 10 marine mammals has generated both support and opposition and has raised concerns about the development of adequate...
Building a Team, Not Just a Building
The best way to resolve construction disputes is to head them off. And the best time to step in is before your contractor is hired. In the private sector, there is no reason to open the...
Long-Range Forecasts of Water-Supplies
Many engineers and water-users have an urgent need for reliable predictions of future rainfall and water supplies, extending many months or years ahead. Correlation of known historic rainfall...
Response of Great Salt Lake to Climate Variability
Levels of Great Salt Lake, Utah, have fluctuated through a range of 6. 2 m in the historic record since the 1840s. In water years 1983-1984, the lake rose 2. 9 m in response to record...
Estimating Climate Change From Hydrologic Response
In the eighty-one hydrographically closed basins within Nevada many large lakes developed during the pluvial climate of the Pleistocene. Pluvial lake area and tributary basin area have...
Issues in Specifying Climate Forcing of Variability
Several issues arise in the specification of the role of climatic forcing of variability of water resources. The effects of human intervention must be removed so that the climate signal...
