Groundwater circulation is influenced by the geology, rock formations, and buildings.
If a region or rock formation is made up of porous and permeable rocks, groundwater will flow through it quite quickly and you may see it by looking at the plants.
Along with the creation of the rocks, geological features like faults, fractures, etc. also aid in the ease with which groundwater may travel.
The flow of groundwater will be especially challenging in a region where the primary soil type is clay or one with low porosity and permeability.
