Abstract:
This paper is based on the studies of existing problems with regards to the storm water in Walgama area
Matara Municipal Council and providing Engineering and Management options through a mathematical
model EPA SWMM5. Several field visits were conducted to the study area in order to investigate the existing
problems and collect the field data for model development. Model was verified with field survey data and the
parameters observed \'odes and canal parameters were varied to identify' influence on output using most
sensitive parameters, engineering options were proposed for storm water problems.
