CNX Resources released the following statement regarding its Shaw 1G Utica shale well in Washington Township, Westmoreland County, Pennsylvania: "Over the weekend, we commenced efforts to remediate the Shaw 1G well in order to arrest the subsurface flow
Eisenhauer also developed a course on subsurface flow
and transport to address vadose and groundwater system challenges related to groundwater depletion.
Constructed wetlands are generally classified into three main categories such as free water surface flow constructed wetlands, subsurface flow
constructed wetlands and hybrid systems depending on the inlet wastewater flow patterns and the type of macrophyte growth .
Nyquist JE, Toran L, Pitman L, Guo L, Lin H (2018) Testing the fill-and-spill model of subsurface flow
using GPR and dye tracing.
Walker and Bong 1981), or the fact that any 1080 transported into the soil was further diluted by subsurface flow
from upslope areas outside the experimental area.
This volume evaluates the performance of horizontal subsurface flow
constructed wetlands in treating domestic wastewater to the limit that can be safely discharged to agricultural drains, providing guidance on the construction, performance, operation, and maintenance of these wetlands of domestic and municipal wastewaters.
The proposed reservoir would recharge the subsurface flow
of karez, shallow wells and tube-wells, protect the agriculture land and human settlements from devastation of floods during flood seasons and develop grazing zones for livestock.
It estimated the numerical solutions of geofluid flow by applying a set of particular solutions of the subsurface flow
It was consisted of four pilot scale horizontal subsurface flow
constructed wetland, which are referenced in this work as CW.
This can be well-studied in the field of soil physics; some of very accurate models including Hydrous  and consol Metaphysics Subsurface Flow
Module  which is used for solving PDEs for pressures that exist between soil and water particles in the porous media.
Physical processes responsible for water movement, driven by climate variables, include evaporation, condensation, precipitation, infiltration, run-off, and subsurface flow
A tracer test was carried out on 22 August 1986 using a combination of rhodamine WT and fluorescein dyes to confirm that Douglas Lake seepage was the source of Carp Creek and to estimate travel time of subsurface flow
. A slug of highly concentrated rhodamine WT and fluorescein dyes (exact concentration not determined) dissolved in 70% ethanol was poured into a 1 m (depth to the water table) deep hole dug approximately 5 m from the Douglas Lake shoreline just west of the UMBS's Lakeside Laboratory and allowed to seep into the ground.
