  1. MIKE11 Structures definition of weirs, culverts, regulating & controlling structures in MIKE11

  2. Location of Structures • river name • chainage • ID: string identification

  3. Weirs • types: • broad crested weir: • calculated Q/h (x-section, dx) • critical flow • special weir: • specified Q/h • valve regulation • head loss factors (energy loss) • geometry • level-width (increasing) • x-section DB

  4. Culverts • attributes: • upstream & downstream invert • length • bed resistance • valve regulation • head loss factors (energy loss) • geometry: • shape • level-width • x-section DB

  5. Regulating (Pump) • specified discharge • types: • function of time (boundary editor) • function of hydraulic conditions: • water level • reservoir inflow

  6. Control Structure • regulated flow  moveable gate • type: • overflow: variable crested weir • underflow: vertical sluice gate • discharge: pump • radial gate: no head loss • attributes: • gate width • sill level (upstream) • max. speed(gate level change per time) • head loss factors (energy loss)
