Deep Underground Science and Engineering, Volume 4, Issue 4, Page 792-799, December 2025.Ground‐borne vibrations are a frequent source of environmental problems. A full‐scale experiment is conducted to validate a 3D numerical model in order to analyze the efficiency of three methods of isolation. Trench barriers and wave‐impeding blocks are impractical and expensive methods of isolation, but mass scatters appear to be an efficient ...

Effects of Subsurface Water Infiltration Systems on Groundwater Table Dynamics in Drained Peat Soils
Hydrological Processes, Volume 39, Issue 12, December 2025.The effects of subsurface water infiltration systems on groundwater table dynamics are captured in six hydrologically relevant parameters for five sites. Water infiltration systems, if applied correctly, reduce the amplitude in groundwater table fluctuations, most notably by raising water tables during dry periods.
