I am very new to the SWMM5 and working on a project in which i have to develop unit hydrograph and pollutograph in SWMM. please help me out.explain me a detailed procedure to develop hydrograph and pollutograph. Actually I have to develop unit area hydrographs for use in SUSTAINs land module and also have to develop pollutographs for each landuse and subcatchment (Based on unit area hydrographs and EMC's).
Thanks in adavance and will be waiting for your valuable suggestions.
Do you really need a unit hydrograph or will a runoff hydrograph suffice for your Sustain modeling?
I am very much thankful to you sir for your quick response.
sir what about pollutograph.
