Why is MIDUSS a better design tool than HEC-1?
There are many programs available for simulating stormwater management. However MIDUSS is probably unique in offering the capability of designing different components of the stormwater system. Programs such as HEC-1 (now known as HMS or Hydraulic Modelling System) are useful for simulating the runoff from a given system when subjected to a particular storm. However the design capabilities are very limited.
