Log-Pearson type III flood-frequency analyses were made of annual series peak-flow records from gaging stations on unregulated streams in Minnesota having watersheds ranging in area from to 2, square miles. These flood discharges were related to watershed and climatic characteristics by using multiple-regression techniques. On the basis of this preliminary regression analysis of. Determine existing drainage areas that contribute to the highway drainage system and the estimated runoff used for design of the existing system.

Equations are available for estimating rural and urban flood-frequency statistics, such as the year flood, for every state, for Puerto Rico, and for the island of Tutuila, American Samoa. Equations are available for estimating other statistics, such as the mean annual flow, monthly mean flows, flow-duration percentiles, and low-flow. Although estimates of design rainfall for reservoirs in the UK have recently been updated, other aspects of the design method and the estimation of probable maximum precipitation (PMP) are dated. Methods for river flood estimation have moved on since the s and there are new and longer-term sources of hydro-meteorological data.

[from old catalog] Abstract. 34 p., 1 l Topics: Rivers--Minnesota., Stream measurements--Minnesota. Publisher: [Minneapolis. Data from 54 stream gages were analyzed, and the drainage area of the gages ranged from 84 to with a mean of square miles.

Streams form with as little as a few acres, and more than 98% of stream miles in Minnesota drain less than 10 square miles, therefore small streams.

The USGS works in partnership with more than 1, Federal, regional, State, Tribal, and local agencies or organizations to maintain and manage a multipurpose network of streamgages that monitor streamflow and (or) water level.

Approximately 8, of the more t USGS streamgages in the network continuously monitor streamflow year-round and are collectively referred to. The evaluation of flood potential is necessary for the design and location of structures that either control flood flows or tha t are subject to possible flooding, and is essential for establishing flood insurance rates.

Some structures must be d~signed so that they will not be damaged or flooded by any probable flood. located on streams that drain areas greater than square miles (mi2) and flow continuously, although in about 18 percent of daily-record gaging stations in Minnesota had drainage areas of less than mi2.

Current stream flows are compared with historical flow data and watersheds are ranked in the following categories (flood, high, normal, low, protected flow).

Weekly stream flow maps and tables are generated on Mondays from April to October. StreamStats Application. StreamStats is a Web application that provides access to an assortment of Geographic Information Systems (GIS) analytical tools that are useful for water-resources planning and management, and for engineering and design purposes.

The map-based user interface can be used to delineate drainage areas for user-selected sites on streams, and then get basin characteristics.

An increase in the range of 10% to 50% is generally appropriate. 4.
