EXAMPLE CALCULATIONS OF POSSIBLE GROUND

2010-12-3  of ground-water inflow from the reservoir to the mine pits. The purpose of this study, conducted in cooperation with the U.S. Bureau of Reclamation, was to provide example calculations of how ground-water inflow could be estimated. Darcy's law was used to calculate one-dimensional inflow from the reservoir to the mine pits.

Assessment of groundwater inflows into Kuteshwar

2011-10-14  The computed inflow to the quarry indicates that a maximum inflow of 32,540 m 3 /day would be expected to the Marwa quarry at floor level of 283 m (amsl). The inflow to the Marwa quarry at quarry floor level under full exposure condition has been computed in the groundwater flow model under second scenario.

2019-11-11  16. Historically groundwater has been extracted at the site to allow for quarrying. When dewatering ceases, the groundwater level will rise at the quarry void and nearby, and groundwater will enter the quarry void creating a lake. The rate of lake level rise has been modelled and is represented

2020-9-30  Abstract. The possibility of estimating groundwater inflow to irrigation drains in Minia, Egypt, using stable isotopes has been explored. The evaporation pan technique described here makes use of small variations in the concentration of naturally occurring stable isotopes (oxygen-18 and deuterium) in irrigation-fed groundwater and surface water as well as agricultural drainage water.
