Entrance Step That Allows Water to Flow

Culvert Hydraulics: Basic Principles

A weir is a flow control cross-section where the discharge and depth of water are related to one another through some predictable relationship. At much higher flows, the culvert entrance is submerged and the flow through the entrance acts like orifice flow.
