Hydrological Modeling: Three Steps
A
Dhaka is surrounded by 6 rivers and canals
1. Basin-Level Modeling: Model developed by
IWM for the GBM basin was used to estimate
future flow changes of Brahmaputra (Jamuna)
River due to climate change.
2. Region-Level Modeling: NCRHD was used to
simulate monsoon seasonal flows and water
levels of the river network in the extended
study area.
3. Detailed Urban Area Modeling: MIKE11 and
MIKE Urban were used for detailed level of
hydrological and hydrodynamic modeling of
the urban drainage system and relevant
catchments.
