Calculation of Discharge and Volume of Snowmelt Runoff from Urbanized Territories

Summary

In some cases the discharges and daily volumes of snowmelt runoff from urbanized territories may exceed the calculated values of rain water discharge from the runoff basin considered. The technical literature cites only the data on the maximum intensities or daily layers of snow melting of small probability (less than 50%), which corresponds to the period of a one-time exceeding over 1,5 years. At the same time, the rain networks are most often calculated for rains with a period of one-time intensity exceeding of 0,33–1 year. On the basis of data on probability distribution curves the most characteristic of snow melting, the values of daily layers of melted runoff at small periods of intensity exceeding are obtained.
