Treatment of NDMA, but not NTDMA, was marginally affected when trace co-contaminants including trichloroethene (TCE) and trichlorofluoromethane (Freon 11) were initially added to feed groundwater, but performance recovered over a few weeks in the continued presence of these compounds.
Correct estimation of evapotranspiration is prerequisite for the precise planning and management of irrigation schemes, hydrological modeling, groundwater recharge, crop performance, and land use planning, etc., and it became much more important in regions of arid and semiarid zones.
In order to estimate the impact of groundwater flow on performance of geothermal heat exchangers in ground source heat pump systems, an equation of conduction advection is established for heat transfer in porous media, and an analytical transient solution is obtained for a line heat source in an infinite medium by means of the Green function analysis.
The effect of natural convection on groundwater-filled BHE performance has been reported mainly from northern Europe.
A groundwater investigation was performed to characterize hydrogeological conditions and well performance in a shallow alluvial aquifer using well logs, step-drawdown tests, and hydrogeochemical data.
Other models such as AdaBoost, Bagging, GAM, and NB also produced acceptable performance in groundwater modelling.
However, the influence of groundwater advection on the performance of the geothermal heat exchanger (GHE) in a GSHP is not still clearly known.
This article presents a numerical study to investigate the combined role of partial well penetration (PWP) and non-Darcy effects concerning the performance of groundwater production wells.
The effects of both direction and rate of groundwater flow on the performance of various types of borehole heat exchanger (BHE) arrays are examined using a two-dimensional coupled heat conduction advection model.
The model explicitly couples a soakwell model with a groundwater model so that the performance of the soakwells is reduced by the increase of groundwater levels.
