Hydraulic structures are large, submerged structures that control the flow of water. These structures are used for a variety of purposes including flood control, water conveyance, navigation, and power generation. They can also be used for recreation and environmental protection. For example, dams and locks help keep floodwaters from damaging nearby areas.
Water is one of the most valuable natural resources. As such, man has developed methods and techniques to harness and control it. Water is vital for agriculture, drinking water, and other human activities. Hydraulic structures have to be designed in a manner that makes them work smoothly and efficiently.

One type of hydraulic lock is a river lock, which uses a pair of gates. These gates are used to regulate the inflow and outflow of water from storage reservoirs and dams. These gates can be either radial or leaf gates.
When designing a hydraulic structure, engineers need to consider the pressure of water. The deeper the water, the higher the water pressure. At five meters below the surface, the water pressure is half times more than what exists at the surface. This is known as Under Pressure, and it is a vital consideration for the design of a dam.
A dam’s release of water can also trigger a flood. When this happens, a fast flood wave can form downstream and overwhelm downstream victims. The rapid change in speed and level can cause people or objects to be stranded on the opposite shores, and even on islands.
Hydraulic systems are made from a variety of materials, including concrete and steel. Depending on their design and operation, these structures are susceptible to wear and tear. Changing weather conditions can cause rot in parts, while corroded steel parts can jam and expand, which affects the smooth operation of the structure. A regular maintenance schedule will help reduce these problems.
Safety at dams is also an essential consideration. The South Island Dam on the Kankakee River in Illinois and the Midtown Dam on the Red River in North Dakota both claimed 15 lives. There have also been a number of severe injuries.
Hydraulics work in locks and dams to allow river water to pass through. Locks allow river water to pass through the complex and provide navigational access through the complex. These locks are steps in the “aquatic staircase” of the lock and dam system. Typical locks are 110 feet wide and 600 feet long. Most lock and dam complexes also include an auxiliary 100-foot lock. They are equipped with emergency gates and are built to accommodate future expansions.
