InfoSWMM
is a discrete time simulation
model that uses the powerful
semi-implicit dynamic solution
scheme (more accurate
than implicit schemes and more stable/robust than explicit schemes)
of the full St. Venant
equations enhanced with
the method of successive
approximation with under-relaxation,
and a variable time step
based on Courant stability
criterion. This rigorous
and very accurate hybrid
method is now the USEPA
standard and FEMA certified. |
