How to Calculate Mean annual flood proposed by natural environment research council?
Mean annual flood proposed by natural environment research council calculator uses Mean Annual Flood = Constant C*Area^(0.94)*Stream Frequency^(0.27)*Slope of the Catchment^(0.16)*Soil Type Index^(1.23)*RSMD^(1.03)*(1+Area of Lakes or Reservoirs)^-0.85 to calculate the Mean Annual Flood, The Mean annual flood proposed by natural environment research council is defined as from the engineering viewpoint, qualitative measures of catchment characteristics are inadequate in themselves, and quantitative measures are necessary to predict flood magnitudes. Flood Studies lead to the above equation for catchments. The constant number depends on the location. Mean Annual Flood is denoted by Q symbol.
How to calculate Mean annual flood proposed by natural environment research council using this online calculator? To use this online calculator for Mean annual flood proposed by natural environment research council, enter Constant C (CNERC), Area (ANERC), Stream Frequency (SF), Slope of the Catchment (SC), Soil Type Index (SO), RSMD (RSMD) & Area of Lakes or Reservoirs (a) and hit the calculate button. Here is how the Mean annual flood proposed by natural environment research council calculation can be explained with given input values -> 25.045 = 0.0315*7.6^(0.94)*5.5^(0.27)*8.7^(0.16)*8.9^(1.23)*49.2^(1.03)*(1+24)^-0.85.
