Because the desolation and erosion depends the valley with time reducing the water table and allowing the water from the cave to diapate.

The karst terrain which creates the geomorphic conditions for sinkholes is a broad topic in the field of geology, and encompasses the study of groundwater, drainage, chemical processes, and many other considerations. Essentially, karst regions are located where the rock below the earth can be dissolved by the acidic groundwater which percolates through it (The Science of Sinkholes). These areas are underlain by soluble rocks such as gypsum, limestone, and dolomite which typically react with carbonic acid (H2CO3) from groundwater to dissolve the rock. Presence of limestone is

Similar to a cave, a sinkhole begins by acidic water dissolving carbonate bedrock creating an underground void. If the void grows close enough to the surface, the structural integrity of the surface material will eventually give way and a sinkhole is formed. These depressions can range in size from a few square yards to over hundreds of acres. The depth of sinkholes can vary from shallow to hundreds of feet. Although there are nearly 16,000 verified sinkholes in the state, the MGS caution there are a great number which have not been reported or documented. Some sinkholes in Missouri are known to be a depth greater than 100 feet though no exact records concerning depths are maintained. Located in western Boone County, the largest known sinkhole in Missouri covers approximately 700 acres. If a sinkhole does occur, it is recommended that a registered geologist or professional engineer be consulted to assist in the stabilization of the sinkhole. Filling a sinkhole, referred to as remediation, generally consists of removing all soil materials down to the bedrock surface and filling it with size-graded material. Larger rocks should be used first with each successive layer consisting of gradually smaller grained material. Geotextile fabric covered by top soil will allow water

New Orleans was built on a marsh. The city was inundated by water during Hurricane Katrina in 2005, causing a tremendous loss of human lives and costing the economy billions of dollars in damage. Since the storm, the U.S. Army Corps of Engineers has built a system of lift stations and levees to control the flow of water around the city. This has created what is best described as a bathtub surrounded by water. To further elaborate, New Orleans is the bath tub, while Lake Pontchartrain and the Mississippi River surround the city. Over the years keeping water from entering the city has become more difficult because the city continues to sink lower below sea level. Subsidence of marshy soils lowers the ground elevation in and around the City of New Orleans. The gradual caving in or sinking of land is known as subsidence.

Initially, earthquakes shape the Earth’s surface by creating mountains and geysers. In the article “Historic Earthquakes,” it reads, “High intensities were observed in the northwest section of Yellowstone National Park. Here, new geysers erupted, and massive slumping caused large cracks in the ground from which steam emitted” (Stover 3). Consequently, when the geo-process of earthquakes occurs, it molds and changes the earth by creating new geothermal

Associated activities may include installing drainage systems, grading slopes, ditching for storm drainages, and conduits for service utilities. The disturbance of natural patterns of runoff and rainwater infiltration through modified drainage can lead to the concentration of water flow at sites that previously only took direct rainwater infiltration; this can result in rapid forming cover-subsidence sinkholes (Waltham et al, 2005, p. 159). The many impervious surfaces used in modified drainage activities also impedes groundwater recharge, which can consequently lower the water

The United States Geological Survey (USGS, n.d.) defines a sinkhole as "an area of ground that has no natural external surface drainage--when it rains, all of the water stays inside the sinkhole and typically drains into the subsurface." Sinkholes vary in size considerably: from a few feet in diameter and one foot of depth, to "hundreds of acres" wide and "more than 100 feet deep," (USGS, n.d.). Some sinkholes form naturally over time, but human intervention such as construction and development projects have been causing the rapid development of sinkholes in the state of Florida. These large-scale projects can have disastrous effects on the economy and environment, as well as public safety. Sinkholes are especially problematic when they occur suddenly, without warning, in urban areas (USGS, n.d.).

The Freeman-Jewett shale formation is a strong indicator of a low-energy/quiet depositional environment. It is likely this layer was originally deposited offshore in a marine environment. This is further supported by the following Bena Gravel formation, which is emblematic of a transitional beach-type environment with pebble size sand and gravel. This coarser layer of sand and gravel overlying the silty and sandy shale could be evidence for a regressive cycle and receding sea levels. The Bena Gravel formation is eroded by Kern River Gravel which creates a disconformity in the stratigraphy. The Kern River Gravel has stream like deposits but since it cuts through the Bena Gravel Formation it is suggestive the Kern River Gravel formation has a delta depositional environment. The Terrace formation suggests a stream depositional environment. If terracing is present, it indicates a decrease in discharge over time. The next formation, Alluvium, is evidence of an alluvial fan deposition, a glacial deposition that has been reworked by meltwater, or of a dried lake bed. (Levin p.86). Regardless of which, the Alluvium formation gives away easily to mass wasting to from the landslide formation.

Studies, conducted in the Midwestern United States, have shown an increased amount to earthquake activity surrounding drilling locations. From 1970 to 200, the region experienced approximately 20 quakes per year; it experienced 29 between 2001 and 2008 with an exponential increase from 2009 to 2011 (Ehrenberg 22). The problems do not seem to be associated with the drilling itself, but with the waste water disposal re-injected back into sandstone below the Earth’s surface. The waste water acts as a lubricate between fault lines causing movement resulting in the shift of bedrock formations. Both advocates and opponents acknowledge the possibility for earthquake damage, however fracking proponents believe the risk is validated by the associated economic

The voids are spaces between grains of sand, or cracks in dense rock. All water beneath the land surface occurs within such void space sand is referred to as underground or subsurface water. Subsurface water occurs in two different zones. One zone, located immediately beneath the land surface in most areas, contains both water and air in the voids. This zone is referred to as the unsaturated zone. Other names for the unsaturated zone are zone of aeration and vadose zone. The unsaturated zone is almost always underlain by a second zone in which all voids are full of water. This zone is defined as the saturated zone. Water in the saturated zone is referred to as ground water and is the only subsurface water available to supply wells and springs. Water table is often misused as a synonym for ground water. However, the water table is actually the boundary between the unsaturated and saturated zones. It represents the upper surface of the ground water. Technically speaking, it is the level at which the hydraulic pressure is equal to atmospheric pressure. The water level found in unused wells is often the same level as the water table. AQUIFERS An aquifer is a saturated geologic formation that will yield a usable quantity of water to a well or spring. Ground water occurs in aquifers under two conditions: confined and unconfined. A confined aquifer is overlain by a confining bed, such as an impermeable layer of clay

The unsaturated zones are soil and geologic materials located between the land surface and the saturated zone. The voids are filled with a combination of air and water. Water in this zone is often refereed to as soil moisture. Below the unsaturated zone is the water table. The water table is the level in the geologic formation below which all voids or cracks are saturated. The water table also can be thought of as the upper surface of the groundwater and top of the saturated zone for an unconfined aquifer. The entire region below the water table is called the saturated zone. In the saturated zones, all voids are filled with water and no air is present. The water in the saturated zone is call groundwater. The distance water has to travel to reach groundwater can range from a few feet to hundreds of feet. Water movement toward groundwater may take hours or years, depending on the depth to the aquifer and the characteristics of the unsaturated zone.
