Help to make a Unit Hydrograph of Reservoir Level - Storage Curve for a Dam

AI Thread Summary
To create a unit hydrograph for a reservoir using flood data, it is essential to utilize hydrological observations and statistical distributions that fit the data, such as Gumbel, LogNormal, and LogPearson Type III. These distributions can help generate flood return periods, which can then be converted into hydrographs for reservoir routing. The discussion highlights the need for a specific procedure that incorporates flood data as input, contrasting it with the more common method using rainfall data. Resources on flood routing and reservoir routing methods, including tabular and finite difference approaches, may provide additional guidance. Overall, further information or methodologies for using flood data in unit hydrograph creation is sought.

Hello!
I'm just asking for a clue on how to make a unit hydrograph Reservoir Level - Storage Curve for a Dam. I have been searching information on internet, but I could not find anything about that. I would appreciate any idea or suggestion.
Thanks!
 
Engineering news on Phys.org
Chadwick & Morfett

page 317 under 'flood routing'
and p318 'reservoir routing'

gives details of a tabular and finite difference method.

Other texts also discuss this under flood routing.

go well
 
Thanks Studiot!
 
Studiot!... I am sorry to bother you, but maybe you can help me giving me some idea!
I collected hydrological observations from a reservoir (three days average flow rates). These annual three day average flow rate were subject to a goodness of fit test; the results showed that Gumbel, LogNormal and LogPearson Type III distributions ave better fit than the other candidate distributions. Then the three distributions are used to generate the various return periods flood and then be converted into hydrograph for the reservoir routing.

But my question is... Do you know how to make a unit hydrograph with flood data as input?
I know how to make it with rainfall as input data; and I have been searching on internet and books but I could not find a procedure where the flood is the input data.
I would appreciate any idea or information.
Thanks!

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
