  1. MIKE Flood An integrated tool for flood plain and storm surge studies MIKE Flood combines • MIKE 11 • MIKE 21

  2. MIKE Flood MIKE Flood is used If a two-dimensional (MIKE21) description is needed in some areas and where significant benefits exist when combined to a one-dimensional (MIKE11) model

  3. MIKE Flood Examples : A detailed velocity pattern is required locally (MIKE21) but exchange of flows with the river is regulated by complex structures (movable gates, culverts, special weirs etc.) simulated in a MIKE11 model A general MIKE11 model for multiple purpose (eg. flow analysis, water quality, sediment transport, flood forecasting) can provide boundary condition to a local two-dimensional area (and vice-versa)

  4. 2-D Model of two-dimensional flow MIKE FLOOD Coupling of MIKE 11 and MIKE 21 • advection-dispersion • hydrodynamics 1-D Model of one-dimensional flow Bay of Bengal, Bangladesh

  5. Types of coupling MIKE 11 boundary to a MIKE 21 boundary Lake, estuary etc. MIKE 11 boundary to a MIKE 21 source point Flood plain

  6. Time Integration • Data exchange at mike11 time step n and n+1 • Different Time step in MIKE11 and MIKE21 • MIKE11 always ahead: MIKE21 value at time step n applied as boundary condition at time step n+1 to progress MIKE11 with the next time step. Following the MIKE11 time step, the MIKE21 executes (smaller) time steps up to new n+1. Mike 21 Mike 11 n+1 n
