Yakima Nitrates

The Issue: Links between nitrate application to the land surface and measured nitrate concentrations in groundwater or surface water are poorly understood in the Yakima River basin due to the variety of potential nitrate sources. Fertilizer-intensive irrigated agriculture has been prevalent in the basin for decades, and since 1994 the growth of dairy operations has resulted in numerous liquid-...

Ecological Stressors - Rocky Coastlines, Mangroves, Marshes, Droughts, and Storms

Coastal estuaries that contain marshes and mangroves are currently being reshaped by changing ocean and atmospheric conditions through prolong drought, sea-level rise and increased extreme storm events. Many projected increases in sea-level are expected to result in loss of tidal wetlands and their component species. In addition, changing sediment loads, extreme tide and storm events, and...

Wetland Restoration in the San Francisco Bay Delta and Pacific Northwest

Estuaries and healthy coastal habitats are among the most productive ecosystems on Earth. They provide a variety of benefits, including habitat and food for fish and wildlife, flood and erosion protection, improved water quality, increased carbon sequestration, as well as beautiful scenery and opportunities for recreation.  Along the U.S. Pacific Coast, both the San Francisco Bay estuary and...

Upper Klamath Basin Groundwater Studies

Since the late 1990s the USGS has worked to characterize the regional groundwater hydrology of the upper Klamath Basin. Research focuses on collecting data to help evaluate the state of the groundwater system and its response to external stresses, and to develop computer models to provide insights useful for water management. These efforts build on earlier USGS studies in the basin going back...

Land use and tsunami hazards in the Pacific Northwest

Tsunamis have the potential to cause considerable damage to communities along the U.S. Pacific Northwest coastline. As coastal communities expand over time, the potential societal impact of tsunami inundation changes.

To understand how community exposure to tsunami hazards may change in coming decades, we projected future development (i.e. urban, residential, and rural), households, and...
