The Westbay MP system is a modular instrumentation system for multilevel groundwater monitoring acquired by Nova Metrix in 2015, the MP system consists of two parts: (1) the casing system and (2) portable probes and tools that provide a compatible data acquisition system. The Westbay casing system is designed to allow the monitoring of multiple ...
Environmental indicator criteria and frameworks have been used to help in their selection and presentation. It can be considered, for example, that there are major subsets of environmental indicators in-line with the Pressure-State-Response model developed by the OECD. One subset of environmental indicators is the collection of ecological indicators which can include physical, biological and ...
In subsurface hydrogeology, drawdown is the reduction in hydraulic head observed at a well in an aquifer, typically due to pumping a well as part of an aquifer test or well test. In surface water hydrology and civil engineering, drawdown refers to the lowering of the surface elevation of a body of water, the water table, the piezometric surface ...
Well clusters are different from nested wells in that each monitoring well is constructed in a separate borehole, as opposed to multiple well casings in a single borehole which is the case with nested wells). A key advantage of a well cluster over a nested well is that there is less potential for vertical leakage and hydraulic short-circuiting ...
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 ...
Survey markers, also called survey marks, survey monuments, or geodetic marks, are objects placed to mark key survey points on the Earth's surface. They are used in geodetic and land surveying . A benchmark is a type of survey marker that indicates elevation ( vertical position ).
The sustainable water supply system is an integrated system including water intake, water utilization, wastewater discharge and treatment and water environmental protection. It requires reducing freshwater and groundwater usage in all sectors of consumption.
In 2007, on the recommendations of the International Water Management Institute, the Indian government allocated ₹ 1,800 crore (equivalent to ₹ 54 billion or US$630 million in 2023) to fund dug-well recharge projects (a dug-well is a wide, shallow well, often lined with concrete) in 100 districts within seven states where water stored in ...
