D. Flood Forecast Model:
Basis: – One dimensional fully hydrodynamic model (MIKE 11 HD) incorporating all major rivers and floodplains. This is linked to a lumped conceptual rainfall-runoff model (MIKE 11 RR) which generates inflows from catchments within the country.

- Total length of modelled rivers = 7270 km.
- No. of catchments =216
- Total number of forecast stations = 30
- Flood maps generated from model results via GIS link to model (MIKE 11 GIS)
- Daily monsoon bulletin & river situation report
- River level forecasts for 24, 48 and 72 hours
- Current warning messages
- Special flood situation report
- Thana inundation status map
- Flood forecast maps
- Monthly flood report
- Dry season bulletin (weekly)
