Submit Your Design Let NDS evaluate and help you with preparation of your submittal drawings and specs. Water stress in plants is caused by the water deficit, as induced possibly by drought or high soil salinity. The prime consequence of water stress in plants is the disruption in the agricultural production, resulting in food shortage. Calculating the runoff volume is more of a hydrology function. Prior to development, the peak discharge due to runoff from this storm = Outflow, or post-development peak discharge downstream of detention ponds; Calculating runoff volumes. The designer must understand the assumptions and calculations contained in the spreadsheets and is responsible for their use. where (L=Length units, T=time units): A = watershed area [L2]. skew the calculation.

We have made the runoff storage volume calculation useful for the international community by 650.0201 Basic Hydrologic Concepts A. the larger the size of the catchment the larger the time of concentration and the smaller the runoff efficiency. The runoff storage volume calculation is only valid for q o / q i in the proper range. The EFH-2, version 2.0.1 (February 2021) software implements the procedures described in Title 210, National Engineering Handbook 650 - Engineering Field Handbook, Chapter 2 (EFH-2), "Estimating Runoff Volume and Peak Discharge".Required information includes watershed characteristics (drainage area, runoff curve number, watershed length, and watershed slope), rainfall amount and rainfall . Use when drop from pipe outlet invert to calculated tailwater is less than the outlet pipe diameter or the invert is flooded up to 0.7 * the outlet pipe diameter.
