Dear Sir,
I have simulated a model in a river reach which is tidal in character. I
submit flow hydrograph as u/s boundary and stage hydrograph as downstream
boundary condition. As tidal river so at the downstream the stage
hydrograph is sinusoidal in character that means two high tide and two low
tide within 24 hours. After simulated the model for one year i have seen
that for the same date like 15 January the upstream discharge is about 500
m3/s and at the downstream is about 2500-3000 m3/s for the same date. How
it is possible as the continuity equation. Did it happed due to tidal
effect or this simulation is wrong or erroneous. Please give me answer
because i submit my thesis work as soon as possible.
You would be kind enough to give me reply as soo as possible.
Your’s sincere
Shihab Hossain.
