Karst Potential & Groundwater Vulnerability of Chalk

Groundwater vulnerability in the Chalk is related to the presence of karst features. The Chalk is a porous carbonate rock subject to dissolution by rainwater or surface water infiltrating and percolating through it. The dissolving power of infiltrating water works upon fractures and other planes of weakness within the rock, over time producing enlarged fissures…

Leck Fell Grip Survey

A series of compartments were identified by the farmer as containing grips and being potential areas for restoration of peat erosion. These compartments were surveyed in the field during March 2015 using previously prepared aerial photography and GIS mapping.

An Introduction to Groundwater Tracers

Other than cave exploration, injected tracers are the only tools available for directly determining groundwater flowpaths and velocities. As cave exploration is limited to only the largest pore spaces within the ground, and only within certain types of rock, tracers are frequently employed to yield information on groundwater systems. Within the UK, injected (or artificial)…
