This concept, along with many other results of tropical deforestation from the Geist and Lambin study, can easily be applied to habitat destruction in general. Shoreline erosion: Coastal erosion is a natural process as storms, waves, tides and other water level changes occur.
The period from 1962 to 1965 was one of drought for the Everglades, and Levee 29 remained closed to allow the Biscayne Aquifer—the fresh water source for South Florida—to stay filled. [85] Animals began to cross Tamiami Trail for the water held in WCA 3, and many were killed by cars.
Other research includes effects on denudation rates; this research is mostly studying how climate [37] and vegetation [38] impact denudation. Research is also being done to find the relationship between denudation and isostasy ; the more denudation occurs, the lighter the crust becomes in an area, which allows for uplift. [ 39 ]
Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. [155] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant or an oil spill. Non-point sources are more diffuse.
During the 1970s, the expansion of irrigation projects had begun to disrupt the flow of water to the marshes; by the early 1980s, it was evident that these had significantly affected water levels. [10] Part of the Hammar Marsh was also drained in 1985 during efforts to prepare the area for oil exploration. [11]
There are five main sources of nutrient pollution. The most common source of nutrient runoff is municipal sewage. This sewage can reach waterways through storm water, leaks, or direct dumping of human sewage into bodies of water. The next biggest sources come from agricultural practices.
The Doña Ana County Flood Commission in the U.S. state of New Mexico defines an arroyo as "a watercourse that conducts an intermittent or ephemeral flow, providing primary drainage for an area of land of 40 acres (160,000 m 2) or larger; or a watercourse which would be expected to flow in excess of one hundred cubic feet per second as the result of a 100 year storm event."
"Over a mile long reach [of the water channel] adds up to over 1.5 acre of land needed for the two stage drainage ditch design". This acreage of land may already be currently used for other purposes or contains infrastructure and subsurface gas or sewer lines. Thus, the larger the channel is, the more soil, and thus, increased funds required to ...
