This report describes the surface- and ground-water resources of North Dakota and the limitations of our understanding of these resources. Ground water and surface water are actually one resource, because they are often hydraulically interconnected. They are discussed separately for convenience. In general, the surface-water resources of the mainstem of the Missouri river are abundant and suitable for most uses. Other rivers may be important locally as water-supply sources, but the quantities of flow are small, quite variable in time, and generally of an unsuitable quality for most uses. Streamflow characteristics of North Dakota reflect its arid to semiarid climate (annual precipitation varies from 13 to 20 inches...

Governmental units that have been identified as having flood hazard areas but do not have detailed base flood information are required to use the ' best available data ' to regulate new development or expansion of existing development in flood prone areas. Information for flood plain management has been identified for 31 governmental units in North Dakota and includes the determination of what data are available regarding flood hazards, hydraulics, and hydrology, and a review of these data to determine their adequacy for use in flood plain management.

Governmental units that have been identified as having flood hazard areas but do not have detailed base flood information are required to use the "best available data" to regulate new development or expansion of existing development in flood prone areas. Information for flood plain management has been identified for 95 governmental units in North Dakota and includes the determination of what data are available regarding flood hazards, hydraulics, and hydrology, and a review of these data to determine their adequacy for use in flood plain management.

A study of seasonally frozen soil was conducted from October 1985 through April 1986 and from October 1986 through April 1987. Three runoff plots were established. On October 30, 1985, 86 mm (millimeters) of water was applied to plot 1, and 43 mm of water was applied to plot 3. No water was applied to plot 2. The winter of 1985-86 had colder-than-normal air temperatures and greater-thannormal precipitation. Some freezing-induced redistribution was measured within the soil profile at some sites. No measurable upward movement of water from the water table to the freezing front was detected in any of the plots.Snowmelt runoff occurred on March 21 and 22. Plot 1 had 14.2 mm of runoff, plot 2 had less than 0.1 mm of...

The Instrumentation that was used to collect data for an investigation of the heat and water transfer through soils during freezing and thawing is described. The study area is 11.3 kilometers southeast of Oakes, N.Dak. Three runoff plots were established. Snow depth, runoff, sou water content, and soil temperature data were collected for each runoff plot. Precipitation, snow density, air temperature, radiation, and ground-water level data also were collected in the study area. The data that were collected during the investigation are presented.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
