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 ...
By 1992, it was the nation's third-largest such state agency, with 1,500 employees and a budget of some $650 million. [2] In 1993, the state merged the DER with the substantially larger Department of Natural Resources, creating the Florida Department of Environmental Protection. [3] Virginia Bass Wetherell was named Secretary of the new agency.
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 ...
Subsurface utility engineering (SUE) refers to a branch of engineering that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost ...
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 ...
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 ...
The Florida Legislature is looking to boost the pay for a depleted state work force and for the third consecutive year has inserted a pay raise in a $116 billion state budget it will soon send to ...
a subsurface (groundwater), drainage model related to: a spacing equation for subsurface pipe drains and open ditches (horizontal drainage) or wells (vertical drainage); see watertable control; a hydrological subsurface drainage model; see soil salinity control for an example of an agro-hydro-salinity subsurface drainage model
