Hi group members,

I am trying to do reservoir routing. I am having stage-storage table for the
reservoir(upto TWL only), and inflow hydrograph details.
I am not having any data like rating curves for the reservoir or stage-discharge
or storage-discharge relationships or table values.

I know only the starting level of the reservoir before the storm event. I know
weir length over which spill occur after reaching the Top water level(TWL).
Spill over weir occur after reaching TWL. Before that no spill or no scouring
too.
Now I am assuming no scouring even spill starts, As i don't have data on
scouring from the reservoir.


My Queries are,

1. I tried to do the puls method. But i struck up with "how to develop the
curves - 2S/del t + O and 2S/del t - O" which is useful for further steps of the
method. I already mentioned above the availability of data with me. I find
difficult with those above data to develop the above curves.

2. I don't know how to develop relation - 2S/del t + O Vs O with the above
available data. Once I got this, I can do other things easily.

2a. How to get stage-discharge or storage-discharge relationship or table values
with the above data of stage-storage table. Even I don't have stage-surface area
values too.

3. My weir length 18 m. How to select the weir coeff.? type of weir is bell
shape. This is the info i have. Spill over weir is in a box type chamber and go
to a channel and go to a next reservoir. Suggest me a good weir coeff. for my
discharge calc. over the weir. I try to use 3. Is it ok.?
I use Q = CL(H^3/2)

4. suggest me some other good method/easy method for the same above problem of
res.routing. Or send me some good literatures on the same subject.

Every efforts from the group would be appreciated.

Thanks in advance.
