ABSTRACT
This chapter describes the methods commonly used for monitoring of parameters relevant to groundwater control systems, including groundwater levels and pumped flow rates, as well as performance indicators. It discusses methods of manual data recording, automatic monitoring using dataloggers and the means to disseminate data. Groundwater control systems should have specific targets – maximum allowable groundwater levels at particular locations. The requirement for monitoring will change during the life cycle of a groundwater control system; timely and accurate monitoring can be vital in identifying and remedying potential problems. The key point is that all groundwater level data should be reported relative to a common datum, and the level of proposed excavation should be known in the same system. Remote sensing techniques are sufficiently advanced that ground levels can be determined by satellite surveillance with sufficient accuracy to be useful to assess the relatively small-scale settlements associated with groundwater lowering.
