Hydraulics of an Ogee Spillway with a Curved Plan: The Cade of Germichai Dam [PDF]
مهندسی منابع آب, 2016 The Crest of an Ogee spillway with a curved plan is longer than that of one with a straight crest; therefore, its capacity for the overflow at any reservoir level is higher than that of the straight-crested spillway. Thus it is a preferred design in most

Comparative Study of Ogee and Stepped Spillway for Enhancement of Energy Dissipation
Science and Technology - An International JournalStepped spillway is one of the oldest drop structures used in the construction of small dams Because of its simple form, its effectiveness as an energy dissipater. With this in regard the project aims to present the hydraulic design of stepped spillway for Ungated Garudeshwar Weir located at 12.10 km downstream of Sardar Sarovar Dam which is analyzed ...

Flood risk in past and future: A case study for the Pawtuxet River's record-breaking March 2010 flood event. [PDF]
J Flood Risk Manag, 2020 Abstract In March 2010, a sequence of three major rainfall events in New England (United States) led to a record‐breaking flooding event in the Pawtuxet River Watershed with a peak flow discharge of about 500‐year return period. After development of hydrological and hydraulic models, a number of factors that played important roles in the impact of this

Flow over Ogee Spillway: Physical and Numerical Model Case Study
Journal of Hydraulic Engineering, 2001 A study was completed to compare flow parameters over a standard ogee-crested spillway using a physical model, numerical model, and existing literature. The physical model was constructed of Plexiglas and placed in a test flume. Pressure taps were installed along the entire length of the spillway.

Discharge coefficients for ogee spillways
Water Supply, 2022 Abstract Discharge over an ogee weir is related to the length of the weir, upstream total head above the weir crest and the discharge coefficient. The discharge coefficient is influenced by several factors; in this study, some parameters that influence discharge coefficients of ogee weirs are investigated. These factors include: the weir
