  1. Introduction hydrologic and hydraulic modelling using MIKE11 (NAM and HD) Gennadiy Donchyts UCEWP, Kiev

  2. Contents • NAM model overview • HD model overview • Building model, calibration and verification • Hydro-meteo (Q, h, P, T, E) • Cross-sections (distance, accuracy, source data) • Structures (bridges, weirs, gates, reservoirs, etc.) • Additional data (DEM/DTM, TIN, Vector, Satellite, Aerial) • Calibration and verification process • Example flood-related projects in Transcarpathia

  3. NAM HD Processes that can be simulated by MIKE11

  4. Hydro and morphological data used for the rainfall-runoff model customization

  5. NAM – introduction • NAM model is deterministic, lumped, conceptual model • NAM is a set of linked mathematical statements describing the behaviour of the land phase of the hydrological cycle

  6. Structure of NAM model • Snow storage • Surface storage • Lower and root zone storage • Groundwater storage

  7. Conceptual diagram of NAM

  8. Data requirments • Model parameters • Initial conditions • Meteorological data • Hydrological data

  9. Hydrologic and meteorological data for NAM • Rainfall (mm) • Potential evapotranspiration (mm) • Temperature (Co) • Discharge (m3/s) • Water level (m)

  10. Mike11 calibration. NAM model • 9 subcatchments • Uzh – 4 subcatchments • Latoritsa – 5 subcatchments

  18. Mike11 HD model • MIKE 11 is a hydrodynamic model that computes unsteady flows in river and estuaries. • Sev-Venan equations • Mass balance • Momentum balance

  19. Data requirments • Model parameters • Initial conditions (Q, h) • Boundary conditions (Q, Q/H) • Lateral inflow (NAM results • Hydraulic structures data
