38. Setting up a River System Setting up a River System in MIKE 11 requires: Topographical Data (.xns11) Digitization of River Network(.nwk11) Physical description (.nwk11) (branch-connections, structures etc.) Boundary conditions (.bnd11) (measured hydro-metric data, time series)(.dfs0) Model specific parameters (Parameter Editor-files) e.g.: Bed resistance, Wave approximation(.hd11) Dispersion, Decay(.ad11) Surface, Root zone, Groundwater descr.(.rr11) MIKE 11

39. Setting up boundary Conditions MIKE 11 Boundary conditions applied at external boundaries Discharge, Q :Upstream of River Lateral Inflow Closed End (Q=0) Discharge Control Pump Water Level, h : Downstream River boundary Outlet in Sea (tide, wind) Water level control Q/h Boundary : Downstream Boundary (Never upstr.) Critical Outflow from Model Q Q Q h or Q/h In general, Boundaries should be located where key investigation area is not directly affected by boundary condition.

40. Data Reliable Data required: ‘GARBAGE IN = GARBAGE OUT’ MIKE 11 Modeling Rule No. 1 : Model results are not more accurate than the accuracy of the underlying data
