Between 1930 and 1937, a dike 66 miles (106 km) long was built around the southern edge of the lake, and a shorter one around the northern edge. It was 34 feet (10 m) tall and 3.5 feet (1.1 m) thick on the lake side, 3 feet (0.91 m) thick on the top, and 2 feet (0.61 m) thick toward land.
The same report predicted that global warming of 2 °C would expose roughly 1-4 billion people to water stress. This would depend on regional patterns of climate change and the socio-economic scenarios. [8]: 558 On water scarcity which is one factor in water insecurity the report finds 1.5-2.5 billion people live water scarce areas.

Generally, water cycle management can be divided into six subsets that approach the issue from varying perspectives: Meteorology, Hydrology, Water resource management, Water Engineering, Water conservation and Environmental monitoring. Recently, politics and socio-economic aspects are also considered in water cycle management due to inequal ...
A portion of the C-38 canal, finished in 1971, now backfilled to restore the Kissimmee River floodplain to a more natural state. An ongoing effort to remedy damage inflicted during the 20th century on the Everglades, a region of tropical wetlands in southern Florida, is the most expensive and comprehensive environmental repair attempt in history.
Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [1] Recharge occurs both naturally (through the water cycle ) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and/or reclaimed water is routed to the subsurface.
