H2OMAP
SWMM 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. |
