Areal rainfall correction coefficients for small urban catchments
Atmospheric Research, 2005Abstract The spatial rainfall variability can have a large effect on the prediction of discharges in urban drainage systems. Areal rainfall correction coefficients are often used to cope with this problem. This paper makes a clear distinction between two types of areal correction coefficients: one for correction of historical data at given time ...

Determination of Surface Drainage Coefficient Through Rainfall Analysis
Journal of Agricultural Engineering (India), 2005The drainage coefficient for agricultural watershed at Central Research Station of PDKV Akola (CRS) was estimated. For this purpose 25 years daily rainfall data was used for its depth- duration- frequency analysis to get one to four consecutive days rainfall values for 2, 5, 10 and 20 years recurrence interval (R.I.) Computed drainage coefficients (DC)

Updated Rainfall Coefficients for Texas—The EBDLKUP-NEW.XLS Tool
World Environmental and Water Resources Congress 2015, 2015EBDLKUP.xls is a spreadsheet tool in current use by the Texas Department of Transportation (TxDOT) engineers and other design engineers for estimating intensity-duration-frequency (IDF) of design rainfall by county; the tool differs from discrete-duration IDF in that it facilitates estimation for real-value durations (not discrete durations).

On the basis of the reliable statistics of rainfall rate and rainfall attenuation for 8 localities in Europe, the spatial correlation coefficient of point rainfall intensity was inferred for each locality from the cumulative distributions of attenuation and rainfall intensity by inversely applying the modified Morita and Higuti rainfall attenuation ...

Natural Hazards, 2015
This article presents a field-based method to assess site- and rainfall-specific runoff coefficients to be expected for a given period of the year. The method is applied to recognize soil uses/covers leading to reduced runoff water supply of gullies in Kinshasa.

Optimum Rainfall Interval and Manning’s Roughness Coefficient for Runoff Simulation
Journal of Hydrologic Engineering, 2008To simulate a runoff hydrograph from an overland plane or from a catchment that is subject to natural rainfall, the use of a computer model is essential. To develop such a model, among other parameters, the modeler is required to specify rainfall interval, rainfall data for that interval, and Manning’s roughness coefficient (Manning’s n ) of the plane ...

Water Excess and Deficits using Coefficient of Variation of Weekly Rainfall
Journal of Agricultural Engineering (India), 2002The weekly rainfall data for a period of 39 years from 1947 to 1985 at Sehore and 35 years weekly rainfall and 17 years evaporation data of Jabalpur, were analysed and the average weekly rainfall (AWR), standard deviation (S) and the coefficient of variation (C) were evaluated.

WATER LOSS EQUATIONS AND COEFFICIENTS TO ESTIMATE RUNOFF FROM RAINFALL1
JAWRA Journal of the American Water Resources Association, 1981ABSTRACTInfiltration models are based on physical characteristics of the soil and initial soil moisture. For a given soil it is based on the initial soil moisture distribution.A computer simulation model for flood runoff systems (FH‐Model) was used to analyze 39 sets of rainfall‐runoff data on four small watersheds ranging in size from 17 to 342 square

Coefficient of variation of annual flood peaks: variability of flood peak and rainfall intensity
Hydrological Processes, 2008AbstractScaling can be a powerful solution for predictions in ungauged basins (PUB). Since becoming a principal scaling tool, the theory concerning the index flood method has been criticized because it requires some scaling conditions that are satisfied in few river basins.
