Document Summary
In some methods, the equation is simple, attaching values to variables is complicated: two principle things we need to know for stormwater management, peak flow, total volume of flow to hold back. Scs curve method is simple and relies on public numbers: design point: at the bottom, where we entering into. Conveyance: taking water away from flow path (extraction, pipe network brings water a lot faster which is not always a good thing because the end of pipe faculty will need to hold more, can help or hinder. End-of-pipe: water is stored (storm water pond, a theoretical storm based on rainfall intensity, occurrences and frequency, these are based on historic rain patterns which is problematic if you try to factor in climate change. Is not the straight line distance, its the actually distance on the ground. Sheet flow occurs on: house roof top, pavement impervious surfaces.
