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 ...
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 by 1908, but had cut only 6 miles (9.7 km) of canals.
Land development and water use have transformed the state, primarily through drainage and infill of the wetlands that once covered most of the peninsula. Much of Florida consists of karst limestone veined with water-filled caves and sinkholes, [2] which provide homes to many species of aquatic life, some unique to particular Florida locations. [3]
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
By around 1910–1912, development of the Floridan aquifer system had already occurred in Fernandina and Jacksonville and south along the east coast of Florida, as well as from Tampa south to Fort Myers on the west coast. Over time, the number of wells increased, as did the finished depths, as demand increased.
The most prominent feature of the state park is the large sinkhole formed by the dissolution of limestone by acidic groundwater over long periods of time. [1] Devil's Millhopper is unique in Florida in terms of its scale; over 100 feet (30 m) of rock layers are exposed.
Geometry of a fully penetrating well drainage system in a uniform, isotropic aquifer Geometry of a partially penetrating well drainage system in an anisotropic layered aquifer The basic, steady state , equation for flow to fully penetrating wells (i.e. wells reaching the impermeable base) in a regularly spaced well field in a uniform unconfined ...
Figure 3. SWMM 5's LID processes include unlimited low-impact development or BMP objects per subcatchment and 5 types of layers. One of the great advances in SWMM 5 was the integration of urban/suburban subsurface flow with the hydraulic computations of the drainage network. This advance is a tremendous improvement over the separate subsurface ...
