Sheet flow must be evaluated like all other stormwater leaving an industrial facility, but it can present a number of unique challenges when making visual observations or collecting …
Sheet flow is flow over plane surfaces. It usually occurs in the headwater of streams. With sheet flow, the friction value (Manning’s n) is an effective rough-ness coefficient that includes the …

Water moves through a watershed as sheet flow, shallow concentrated flow, open channel or some combination of these. The type that occurs is a function of the conveyance system and …
Sheet flow - Wikipedia
Sheet flow is described as overland flow that happens in a continuous sheet, characterized by relatively high frequency and low magnitude, and is limited to conditions of laminar flow. [1]
Time of Concentration - HydroCAD Stormwater Modeling Software
By definition, sheet flow occurs only over plane surfaces at the head of the watershed. Due to surface irregularities, sheet flow will eventually transition to shallow concentrated flow. The …
Water moves through a watershed as sheet flow, shallow concentrated flow, swales, open channels, street gutters, storm sewers, or some combination of these. This section describes …
Surface flow—In figure 15–1, point 1 represents a loca-tion where precipitation falls on a watershed. Surface runoff is represented by lines with arrows showing travel along the surface …
Sheet Flow • Storm water in a thin layer, resembling thin film or “sheet” • Slow Flow • Not in distinct channels • NRCS defines the transition point of sheet flow to shallow concentrated flow …
Sheet flow to open space (SOS) is a group of best management practices (BMPs) designed to disperse concentrated runof to sheet flow into filter strips or a riparian bufer. An SOS reduces …
Though only one of the studies focused on the length of sheet flow (McCuen and Spiess), several give useful insights on the appropriate length, roughness, and depth related to sheet flow. For …
