In addition, we have two others which provide vital in-depth information, Hydraulic System Valves and Components and Hydraulic System Equipment. The depth of flow was based on observed or historic high water marks. The use of servo valves for this task is not recommended. For example, a 60-foot wide bridge perpendicular to the stream has a hydraulic length of 60 feet. If it is known that a bridge provides a significant obstacle to flow and is responsible for much of the flooding that occurs, with a knowledge of bridge hydraulics it may be possible to design improvement works that will help to alleviate the problem. Hydraulic systems work by using pressurized fluid to power an engine. An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. This is the case, for example, with the control edges of continuously adjustable valves whereby deflecting the valve control spool creates two adjustable orifices between which the motor (cylinder) is located (Figure H 15).
