Probable maximum flood definition

Probable maximum flood means the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the drainage basin.

Probable maximum flood or "PMF" means the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the drainage basin under study. The "PMF" is derived from the probable maximum precipitation and is determined by using a hydrologic model to simulate the drainage basin's response to those critical conditions which produce the most severe flood runoff.

Probable maximum flood or “PMF” means the flood runoff expected from the most severe combination of crit- ical meteorologic and hydrologic conditions that are rea- sonably possible in the region, including rain and snow where applicable. 1/2 PMF is that flood represented by the flood hydrograph with ordinates equal to 1/2 the cor- responding ordinates of the PMF hydrograph.

Examples of Probable maximum flood in a sentence

• Probable maximum flood means the most severe flood that is considered probable at a site.

• PMF – Probable maximum flood, 7081 m3/s, is a deterministically determined value of the highest still possible flood at the Krško site.

• Probable maximum flood refers to the most extreme flood that could theoretically occur based on maximum rainfall and maximum runoff in a watershed.

Probable maximum flood. (PMF) means the most severe flood considered possible in a specific region based on the Probable Maximum Precipitation (PMP), as determined by the National Weather Service.

Probable maximum flood means the flood that may be expected from the most severe combination of critical meteorological and hydrologic conditions that are reasonably possible in the region, and is derived from probable maximum precipitation, the theoretical greatest depth of precipitation for a given duration that is physically possible over a particular drainage area at a certain time of year. The probable maximum precipitation within designated zones in Iowa has been determined by the National Weather Service. The probable maximum flood for any location within Iowa is determined by the department.

Probable maximum flood or "PMF" means the theoretically largest flood resulting from the most severe combination of meteorological and hydrological conditions that could conceivably occur in the drainage basin. The PMF is the runoff resulting from the Probable Maximum Precipitation.
