Estimates of annual peak-streamflow frequency are needed for flood-plain management, assessment of flood risk, and design of structures, such as roads, bridges, culverts, dams, and levees.
A method of improving our estimates of statistics used to describe flood frequency, taking into account information obtained from the stream whose flood frequency is being investigated.
Stream water quality is affected by amount of impermeable surface in the basin; construction; reservoirs; sanitary sewer systems; land use and population density; road salt; animal waste; lawn and agricultural fertilizers, pesticides, and herbicides.
To better understand the exchange of groundwater and surface water, we coupled groundwater monitoring at the stream bank with nearby gages in the stream. Describes the procedure and results from several areas.
Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for water chemistry and mercury in fish tissue to establish unbiased baseline data.
Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for fish and aquatic insects (macroinvertebrates) to establish unbiased baseline data.
USGS stream-water-quality monitoring network for Georgia represents an aggregation of smaller networks and individual monitoring stations, with map and link to data.
Describes project to identify sources of fecal coliform bacteria by ribotyping to develop the use of Maximum Daily Load (TMDL) values for contaminated stream segments in Virginia.
