Determination of Maximum Runoff of a Locality | Sanitary Engineering
Following procedure is followed in the determination of the maximum runoff of a large locality: (i) The total area of a the locality is divided into smaller units, from where the water flows in various inlets. (ii) The time-area diagrams for each area so divided is obtained and plotted. (iii) Now the cumulative time-area diagram is plotted step by step. [...]
