Hydrolics - Lab Report ExamplePressures are examined at low, mid and also at high head for the hills conditions.The spillway is one of the most cardinal structures that should be given priority in a dam project. Spillways constructed along with the dams help in controlling excess water or flood thusly ensuring the safety of the project. It is also vital that the design of the spillway facilities be done with enough capacity to help avoid overtopping of the dam, especially where an earth fill or rock fill dam type is used for the purpose of the project.The ogee- leaded spillway has superior hydraulic characteristics. It has the ability to pass flow efficiently and safely when it is correctly designed, with good flow measuring capabilities and this has enabled its application in a variety of situations by engineers. Though much is understood about the ogee shape and about its flow characteristics, it is also clear that a slight deviation from any conventional design parameter like c hange in the upstream flow conditions, a slightly modified crest shape or construction variations can significantly alter properties of the flow. These minor adjustments require that engineers carry out evaluation of the crest and also to determine whether the change or deviation will adversely affect the performance of the spillway or not.The ski jump spillways are grassroots in their design as they transfer the excess water from behind the dam. They usually have a flip lip and a dissipater basin which helps puddle a hydraulic jump and therefore protecting the toe of the dam from erosion.. An Ogee spillway was properly installed and the highest discharge was chosen and then using the weir boards, we created a USBR symbol 1 stilling basin, with a hydraulic jump being within the stilling basin. We also ensured that the gradient on the flume was set at 3%. . Similarly a ski jump spillway was properly installed and the highest discharge was chosen and then using the weir boards, we created a USBR Type 1 stilling
