Answer the following statement(s) true (T) or false (F)
1. Because of the continuity equation, the slow-moving water upstream of a culvert has an increased depth, and the faster water in the culvert is shallower. 2. Length of the culvert is a factor that affects flow through a culvert. 3. Upstream (headwater) depth is determined by the stream. 4. To compute the headwater depth for a culvert operating under inlet control, only the flow rate Q and the entrance size and shape must be taken into consideration. 5. The proper method used to determine headwater depth for any culvert problem is to guess the type of control.
