Dear Friends,
I need some ideas on a problem I am facing at work. I have attached a sheet with has a rough picture of scenario. I urge you to please keep open the picture while reading my problem.
Problem:- There is a small wall in a water stream. Due to the small wall the water stream upside of the wall gets a height of H1 while after falling from the small wall it gets a height of H2. As you can see in the picture the height of water down stream is lesser than the height of the small wall.
Now the condition is changed.
Somewhere in the down stream we made created some restriction which caused rise in the downstream water level i.e. H3. This H3 height is higher than height of the wall, let's say it generates delta h difference.
Discharge Q is same. Consider there is no changes in Area.
Now my question is that if this situation happens what will be its effect on the water height at upstream? Will upstream level H1 change to H4 which will be higher than H1, or will it remain same until the two water level matches with each other.
