Central Columbia Plateau - Yakima River Basin

The Central Columbia Plateau/Yakima River Basin (CCYK) National Water-Quality Assessment (NAWQA) study unit is located in Central Washington, USA. The study unit is dominated by intensive agricultural practices, with irrigated agriculture a common practice for crop production (see study area description). Due to the intensive...

Hanford

Located on 586 square miles in southeastern Washington, the U.S. Department of Energy's (USDOE) Hanford Site was established during World War II as part of the Manhattan Project to produce plutonium for nuclear weapons. As a result of plutonium processing and operation of nine nuclear reactors, large volumes of liquid wastes have been generated and discharged to the ground.

The USDOE...

Probability of Streamflow Permanence (PROSPER)

PRObability of Streamflow PERmanence (PROSPER)

Rivers and streams are constantly changing. Streamflows can change throughout the year and between years due to snowmelt, precipitation, diversions, and return flows. For many streams, these fluctuations determine whether a stream has year-round flow or not. PROSPER is a project initiated to better understand what causes these fluctuations...

Characterization and Numerical Simulation of the Puyallup River Watershed

Groundwater is an important resource for domestic, commercial, and industrial usage in the Puyallup River Watershed, and groundwater discharge helps maintain late-summer and early-fall streamflow (baseflow) in many area streams. Consequently, as the population grows, and commercial and industrial activity increase, so does the demand for groundwater. However, the quantity of usable groundwater...

Quincy Groundwater

The Issue: Since 1952, water diverted from the Columbia River for irrigation in parts of the Quincy Subarea in eastern Washington has resulted in rising groundwater levels and increased groundwater flows and storage. Managers of groundwater in the area need a better understanding of the flow system before and after the start of irrigation.

National Assessment of Coastal Vulnerability to Sea Level Rise

The original national coastal vulnerability index (CVI) assessment was motivated by expected accelerated sea-level rise (SLR) and the uncertainty in the response of the coastline to SLR. This research was conducted between 1999 and 2001, and is currently being updated using new data sources and methodology. This original study was part of the ...

Glaciers and Snowpack

Glaciers, snow, and ice sheets are important components of the Earth's water and climate. They respond to and indicate changes in climate, as well as exerting an influence on global and regional climate. They also have an effect on water resources, serving as natural reservoirs. Measuring changes in the size and volume of glaciers and snowpacks provides one direct way of knowing what kind of...
