A “nested” design storm distribution, such as SCS Type Type I, IA, II, and III, or the frequency storm in HEC-HMS, is an artificial rainfall distribution using precipitation depth-duration-frequency data.…
A “nested” design storm distribution, such as SCS Type Type I, IA, II, and III, or the frequency storm in HEC-HMS, is an artificial rainfall distribution using precipitation depth-duration-frequency data.…
Historically Probable maximum precipitation (PMP) rainfall depths for spillway design were estimated using NOAA procedure and methodology such as HMR 51 and HMR 52. However, since HMR 51 and HMR…
This post is to explain how to set up an HMR 52 storm in HEC-HMS by using HEC-MetVue PMS parameters and how to optimize it by setting a objective goal…
Probable maximum precipitation (PMP) is theoretically the greatest precipitation for a given duration that is physically possible over a given size storm area at a particular geographic location. Probable maximum…
