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]
A swale is a shady spot, or a sunken or marshy place. [1] In US usage in particular, it is a shallow channel with gently sloping sides. Such a swale may be either natural or human-made. Artificial swales are often infiltration basins, designed to manage water runoff, filter pollutants, and increase rainwater infiltration. [2]
In geotechnical engineering, an interceptor ditch is a small ditch or channel constructed to intercept and drain water to an area where it can be safely discharged. [1] These are used for excavation purposes of limited depth made in a coarse-grained soils. These are constructed around an area to be dewatered.
The OTA plan concluded that conservation, water banking, and changing water pricing schemes would be more cost effective than building the pipeline. [ 5 ] A 2012 Bureau of Reclamation study investigated schemes to bring water to California using an undersea pipeline from the mouth of the Columbia River on the Oregon–Washington border ...
Rain gardens are constructed throughout the city to manage storm water and to improve the water quality of city waterways. [19] The care and tending of rain gardens is a partnership between the NYC DEP and a group of citizen volunteers called "harbor protectors". Rain gardens are inspected and cleaned at least once a week. [20]

An interceptor drainage swale in the middle of the berm is also helpful or the back of the berm can be terraced with retaining walls. On sloping sites, runoff may cause problems. A drainage swale or gully can be built to divert water around the house, or a gravel-filled trench with a drain tile can be installed along with footing drains.
The purpose of these structures is to divert water into the various canals and to keep them full. When over full, they dump excess water back into either streams or other canals. Among the simplest is a low dam across a shallow stream, forcing all of the water to one side to allow it to be easily collected in a canal. This can keep a canal full ...
