Flow routing equations

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.
