The use of sprinkler irrigation and micro-irrigation systems decreases the risk of waterlogging and erosion. [34] Where practicable, using treated wastewater makes more water available to other users [ 34 ] Maintaining flood flows downstream of the dams can ensure that an adequate area is flooded each year, supporting, amongst other objectives ...
This type of irrigation is relatively new with research and development into its practice and modelling started in early 1980s. [3] Surge Irrigation is a variant of furrow irrigation where the water supply is pulsed on and off in planned time periods (e.g. on for 1 hour off for 1½ hour).
Roots can survive waterlogging by forming aerenchyma, inducing anaerobic metabolism, and changing root system architecture. [14] In irrigated agricultural land, waterlogging is often accompanied by soil salinity as waterlogged soils prevent leaching of the salts imported by the irrigation water.
Rainwater harvesting (RWH) is the process of collecting and storing rainwater rather than letting it run off. Rainwater harvesting systems are increasingly becoming an integral part of the sustainable rainwater management "toolkit" [5] and are widely used in homes, home-scale projects, schools and hospitals for a variety of purposes including watering gardens, livestock, [6] irrigation, home ...
Drainage through subsurface drains and drainage channels is essential to prevent a deterioration of crop yields from waterlogging and soil salinization caused by irrigation. By 2003, more than 20,000 square kilometres (7,700 sq mi) have been equipped with a subsurface drainage system and approximately 7.2 square kilometres (2.8 sq mi) of water ...
An elaborate system of flood way defenses can be found in the Canadian province of Manitoba. The Red River flows northward from the United States, passing through the city of Winnipeg (where it meets the Assiniboine River) and into Lake Winnipeg. As is the case with all north-flowing rivers in the temperate zone of the Northern Hemisphere, snow ...
Water Sensitive Urban Design with Green Infrastructure in the bottom right corner.. Water-sensitive urban design (WSUD) is a land planning and engineering design approach which integrates the urban water cycle, including stormwater, groundwater, and wastewater management and water supply, into urban design to minimise environmental degradation and improve aesthetic and recreational appeal.

A small center pivot system from beginning to end. Irrigation equipment can also be configured to move in a straight line, where it is termed a lateral move, linear move, wheel move or side-roll irrigation system. [11] [12] In these systems the water is supplied by an irrigation channel running the length of the field. The channel is positioned ...
