Stoplogs are hydraulic engineering control elements that are used in floodgates to adjust the water level or discharge in a river, canal, or reservoir. Stoplogs are designed to cut off or stop flow through a conduit. They are typically long rectangular timber beams or boards that are placed on top of each other and dropped into premade slots ...
Many of the original mechanisms to control and divert the water's flow - such as stop logs, penstocks, and gate valves - are also still in use. [3] In recent years, water control structures have been installed to assist with regulation of water levels in the canal and to cater for varying flow rates.
Watertable control. In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage. Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the ...
Floodgate. Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm ...
1: Tube connecting the chamber to the high water side of the sluice 2: Gates to regulate the water level in the chamber. Only one gate may be opened at a time 3: Tube connecting the chamber to the low water side of the sluice 4: The chamber in which the water level can be controlled 5: Door with larger surface 6: Door with smaller surface.
Waterlogging water is the saturation of soil with water. [1] Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail. In extreme cases of prolonged waterlogging, anaerobiosis occurs, the roots of mesophytes suffer, and the subsurface ...
Tainter gate being constructed, in 1936, on the upper Mississippi River, Lock and Dam No. 7 (Onalaska Dam), La Crescent, Minnesota (USACE) Stevenson Dam Tainter Gate on the Housatonic River in Connecticut. The Tainter gate is a type of radial arm floodgate used in dams and canal locks to control water flow.
Silt fence. A silt fence, sometimes (misleadingly) called a "filter fence," [1] is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and seas from sediment (loose soil) in stormwater runoff. Silt fences are widely used on construction sites in North America and elsewhere ...
