A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. [1] Check dams themselves are not a type of new technology; rather, they are an ancient technique dating from the second century AD. [ 2 ]
Silt Fence installed on a construction site.. A sediment control is a practice or device designed to keep eroded soil on a construction site, so that it does not wash off and cause water pollution to a nearby stream, river, lake, or sea.
Silt fence installed up-slope of a vegetated stream buffer. 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.
Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater.Recharge is the primary method through which water enters an aquifer.
Cross Sectional Diagram of a Two Stage Drainage Ditch . A drainage ditch is a depression in the land created to channel water.Drainage ditches are typically formed around low-lying areas, roadsides or fields proximate to a water body or created to channel water from a more distant water source for the purpose of plant irrigation.
The MS Mitch Mitchell Floodway, formerly the Wichita-Valley Center Floodway and known locally as “The Big Ditch”, is a canal in Wichita, Kansas, United States. [1] Built in the 1950s after a series of floods in the preceding decades, the Floodway diverts water from Chisholm Creek, the Little Arkansas River, and the Arkansas River to the west, around central Wichita, before emptying back ...
The mill was established in 1846 by Dr. Edward Turner Bale on property in Rancho Carne Humana land grant. Bale lived near the site until his death in 1849. The gristmill and granary were built with local materials, Douglas firs and coast redwoods. Some timbers were cut to length with the bark left on, while others were roughed out with hand tools.
The trail forks right; the drainage ditch to the left. A water bar or interceptor dyke is a road or trail construction feature that is used to prevent erosion on sloping roads, cleared paths through woodland (for utility companies such as electricity pylons), or other accessways by reducing flow length. It is a diagonal channel across the road ...
