The algae have a marketing problem.  While the scientific community may appreciate the important roles algae play as the base of the food chain in aquatic ecosystems, their contributions to global CO2-O2 cycling and practical applications are

Integrated water resources planning is an example of a large-scale, long-term infrastructure planning problem that is impacted by climate change and multiple potential design alternatives and goals. Traditionally, simulation models were used to

The City of Boulder is responsible for supplying reliable, high-quality treated water to 120,000 customers. The reliability and quality of the water supply result from short-term operational decisions, long-term planning efforts and policy

Profound changes in hydrology are occurring in Arctic and sub-Arctic regions.  The Yukon River Watershed, covering 330,000 square miles in Alaska and western Canada, is no exception.  Since 2006 the U.S. Geological Survey (USGS) and the

Urban development leads to changes in stormflow and baseflow, although the magnitude of these changes varies by city.  This presentation will examine trends in streamflow with urbanization at the national scale (across the United States) and in

Over a billion people globally depend on snowmelt runoff to meet water demands, predominantly from snow that accumulates annually in mid-latitude mountains. Decades of observations show that this natural reservoir is at risk; snow water equivalent

Poised at the interface of rivers, ocean, atmosphere and dense human settlement, estuaries are driven by a large array of natural and anthropogenic forces. Long-term study of San Francisco Bay illustrates responses to five common agents of change

In the McMurdo Dry Valleys of Antarctica (MDV), streams are an important source of water and hydrologic connectivity between glaciers and lakes across the valleys, however, these streams only run for a few weeks to a few months out of the year.

Zinc concentrations before and after the implementation of remediation strategies were examined in three sub-watersheds in southwestern Colorado. Three tributaries to the Animas River (Cement Creek, Mineral Creek, and the Upper Animas River) were

Much is still unknown about the current permafrost and hydrological conditions of the Gates of the Arctic National Park and Preserve. This study addresses the question of how thermal and hydrogeologic properties of the subsurface may affect active
