New sinkholes have been correlated to land-use practices (Newton, 1986). Induced sinkholes are conceptually divided into two types: those resulting from ground-water pumping (Sinclair, 1982) and those related to construction and development practices. Modified drainage and diverted surface water commonly accompany construction activities and can lead to focused infiltration of surfacerunoff, flooding, and erosion of sinkhole prone earth materials.
Manmade impoundments used to treat or store industrial process water, sewage effluent, or runoff can also create a significant increase in the load bearing on the supporting geologic materials, causing sinkholes to form.
Other construction activities that can induce sinkholes include the erection of structures, well drilling, dewatering foundations, and mining.
As we continue to undermine the crustal infrastructure it is almost certain that sinkholes will become more prevalent. Knowing what might be under your home could be a good thing to know.
