MIKE 11 provides an array of computational methods for steady and unsteady flow in branched and looped channel networks, and flood plains. MIKE 11 is applicable to flow conditions ranging from steep river flows to tidally influenced narrow estuaries, and describes subcritical and supercritical flow locally. MIKE 11 includes advanced formulations for simulating flow through a variety of standard structures as well as complex structures such as operational structure or dambreak structures.
