| Abstract | This study presents the application of a hydrodynamic numerical
model (MIKE 11) based on full Saint Venant equations to the
Ganges-Brahmaputra river system of Bangladesh. The prime obj ective of
this study is to investigate the hydraulic impact of propos ed barrage on
the river Brahmaputra. It has bee n suggested by National Water Plan (NWP),
that the barrage on the river Brahmaputra will be final solution for full
development of main river resources when all the regional river resource
potential will be finished. The barrage will be constructed to divert the
water for irrigation and hydropower generation . Now the huge diversion
may change the morphological equilibrium of the river. Spec ially the
lowering of discharge at downstream may effect navigation adversely and
lead saline intrusion far inland. This type of impact may be studied with
the help of numerical model.
The total work includes calibration of the mode l, validation of the
model and finally its application. The model covers an area of about
40,000 km2 consisting of 20 subcatchments and 17 major and minor rivers.
A total 29 wat e r leve ls points uniformly distributed over the entire are a
are considered for calibration. One year of data has been used for those
water level stations were used for calibration. The model has been calibrated and validated successfully.
The model has been applied to study the impact of barrage. The
barrage effect has been incorporated by the option of regulated structure.
The regulation of flow through the structures were determiued by the
following criteria.: Irrigation , Navigation and salinity and hydropower
generation criteria. In fact the purpose of the barrage is the optimal
utilization of water resources . So release policy should be s uch that it
should satisfy all the demands with minimum loss. In the study first
priority has bee given to the irrigation demand . The simulation of the
model with barrage option has been done for one year. Comparison between
simulated and estimated result shows the effectiveness of the proposed
solution. |
