They began by taxing counties that would be affected by the drainage attempts, at 5 cents an acre, and formed the Everglades Drainage District in 1907. [3] Broward asked James O. Wright—an engineer on loan to the State of Florida from the USDA's Bureau of Drainage Investigations—to draw up plans for drainage in 1906. Two dredges were built ...
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
The program also contains an example of the hydrograph of an agricultural subsurface drainage system for which the value of A can be obtained from the system's characteristics. [9] Raven is a robust and flexible hydrological modelling framework, designed for application to challenging hydrological problems in academia and practice. This fully ...
Map of a well field for subsurface drainage with radial flow across concentrical cylinders representing the equipotentials. Both systems serve the same purposes, namely water table control and soil salinity control. Both systems can facilitate the reuse of drainage water (e.g. for irrigation), but wells offer more flexibility.
The figure illustrates the most used irrigation techniques as well as the least used options for treatment and recycling of water drainage. Collecting nutrient-rich irrigation water in reservoirs and pumping them back to crop fields during drought periods is an affordable practice and gaining increasing popularity among farmers in states like ...
Just offshore of the Florida Keys along the edge of the Florida Straits is the Florida Reef (also known as the Florida Reef Tract), separated from the keys by the Hawk Channel. The Florida Reef extends 170 miles (270 km) from Fowey Rocks just east of Soldier Key to just south of the Marquesas Keys.

Parameters of horizontal drainage Parameters of vertical drainage. The subsurface field drainage systems consist of horizontal or slightly sloping channels made in the soil; they can be open ditches, trenches, filled with brushwood and a soil cap, filled with stones and a soil cap, buried pipe drains, tile drains, or mole drains, but they can ...
