Dear colleague,

I send you our paper about this problem.

I hope that will help you.

Best regards

As spill way is the measure structure which controls the safety in High floods

definitely it will have its bearing on the design of Dams.

The spill way even though conceived and designed may have to be changed when actual construction starts based on the geological, structural and Hydraulic data. to suit the conditions.

Hello,

You can see : ''HYDRAULICS OF SPILLWAYS AND ENERGY DISSIPATORS'' 

R. M. Khatsuria, it's good.

Spillway protect the dam from overtopping (I mean flooding) so the spillway should be designed to carry the required excess water by providing suitable depths, widths, lengths and energy dissipation in form of stilling basins at the end.
