Introduction In the winter of 2013 a sinkhole took the life of Jeffrey Bush in Seffner, Florida. He was lying in bed when the ground collapsed beneath his bedroom. Death from sinkhole formation is rare, but sinkhole collapses are a common occurrence throughout the state of Florida (Brinkmann, 2013, p.1). Natural hazards, such as sinkholes, can detrimentally impact society and the environment. Indeed, sinkholes can reroute surface runoff into aquifers; cause structural damage to roads and buildings; drain wetlands; and as shown in the example above, have fatal consequences.
Florida’s growing population corresponds with an increase in urbanization throughout the state, which results in the accelerated development of groundwater and land resources. Sinkholes are naturally occurring phenomena, but their increasing frequency throughout Florida correlates with the accelerated development of these resources (Tihansky, 1999, p.121). Together, Figures 1 and 2 visually display the correlation between Florida’s growing population and the increase in sinkhole development from 1960 to 2000.
Anthropogenic factors such as groundwater pumping, combined with certain environmental conditions associated with a lowered base water level (e.g. drought and hurricanes), can result in sinkhole development. For example, the excessive pumping of groundwater can create subsurface voids because of the lowering of the water table, which can lead to the development of sinkholes due to gravity and the
The Everglades restoration project, which established to clean up ecosystems and waterways for both current and future generations, has encountered many difficulties stemming from either damage that has been done to the environment was in a fact a result of mother-nature, or a result from the activities pursued by mankind. The case involving the South Florida Water Management District can be argued to have been caused by the agencies' activities within the
“There are natural hazards, but disasters are the result of human actions that put people and property in harm’s way” (Cigler 2007: 64). Throughout history New Orleans has been continuously altered by the presence of humans through the creation of levees and canals, the introduction of artificial irrigation systems, and through human induced processes that have ultimately accelerated the process of land degradation and erosion. While a natural hazard struck New Orleans in 2005, the disaster portion resulting from Hurricane Katrina was a result of human induced interactions throughout the history of New Orleans.
A concrete network of canals was designed to bring water from the lake area to surrounding farmland in the dry season. Florida was becoming a booming area and more people came and more acres of the Everglades were cleared for farms, ranches, housing, roads, and railways. And more and more; the Everglades were dying (Miami Museum of Science, 1995).
Groundwater is the largest and most available usable source of drinking water in the state. There is a vast and mysterious system of caves and natural springs in North Central Florida. The cave system within the aquifer is one of the most amazing parts. The caves are remarkable in many ways. They are among the deepest and longest in the world, let alone the U.S. Another amazing aspect of the system is the purity of the water. The springs collectively produce billions of gallons of crystal clear water per day. The whole system stems from the Florida Aquifer that rests under the entire state. When most people think of Florida, they think of the weather and the beaches, but its the springs and the whole water
The purpose of this paper is to define karst topography as it appears in the United States, to illustrate how natural chemical processes facilitate sinkhole development, and to present a brief overview of how modern geotechnical and hydrogeological specialists are attempting to solve the sinkhole problem through innovative engineering design and land study. Ultimately, the goal from an engineering perspective is to understand karst and sinkholes on a fundamental level so that a variety of case-by-case solutions may be made available to keep the public safe. This is certainly one geological problem where the stakes are high, and humankind is competing against the very ground it stands upon. The question is: Will filling holes in engineering knowledge translate to preventing sinkholes from causing any more damage than they already have?
Vast beaches, amusement parks and resorts are all places that are abundant in Florida. There are numerous interesting things to visit, and numerous neighborhood’s that would suit a family of any kind scattered through the state. The Unique clash of skyscraper cities that are minutes away from the ocean front and year round warm temperatures make this an ideal place for people who are seeking warm weather and a change of scenery. It also makes Florida a very popular place to live, with 365 thousand people moving here a year, around 25 thousand of which move into Marion and the surrounding county 's, this state has a large influx of new residence which has made Florida the 3rd most populated state in America (Business Insider, ppiofmarioncounty.org). The massive influx of new people leads to a near constant expansion of cities and towns that are filled to the max, making the amount of natural forest in Florida shrink daily. The Florida Department of Environmental Protection’s report, History of Florida 's Conservation Lands, states:
When a sinkhole is about to form, there are no distinct signs. Even if there are clear signs through cracks on the street or cracks in the house, by the time we realize, our homes would be sinking down into the sinkhole. There has been multiple cases in Florida where families have been left devastated due to sinkholes. In August 2013, Summer Bay Resort, Disney-area timeshare development in Clermont Florida, a big sinkhole opened up swallowing two buildings. As people were inside the building, the ceiling started to crack and popping noises were made from the buildings. Luckily, all the residents were evacuated and no one was injured. But, not all the cases are fortunate like this one. In March of 2012, thirty seven year old Jeffery Bush disappeared into a huge sinkhole that opened up directly under his bedroom while he was sleeping. Unfortunately, his body was never recovered from the sinkhole and the two residences next to Jeffery’s also
Ground water is a very important part of our fresh water supply and yet, it’s depleting at a faster rate than what can be replenished. According to Kally Worm “Groundwater is the second largest reserve of freshwater on earth. It also makes up 40% of the freshwater used in the U.S. alone.” This ground water is usually found in what is called an aquifer. An aquifer is found towards the lower layers of the soil. The problem with these aquifers it that their recharge rate is slow making it non- renewable. These water supplies being non- re We are overusing these water supplies. When ground water is used to a level of where it can’t recover, it affects the ground. Sinkholes can be formed when there is a aquifer that has water being drawn from it, but not letting it get back to par. Other problems can also occur is too much ground water is pumped out near coasts. This creates what’s called salt water intrusion. Salt water intrusion is when the ocean water mixes with the fresh ground water. This increases the salinity of the water making
In the early 20th century, the Army Corps of Engineers drained the Everglades and developed plantations as well as other structures, something other settlers of south Florida could not do. The implementation of the organized elimination of water in the Everglades resulted in catastrophe causing massive damage to the ecosystem. Hypersalinity in the southern estuaries and water diverted east poisoned the fresh water estuaries on the Atlantic coast devastating valuable fisheries and marine breeding grounds; saltwater incursion is becoming a serious threat to urban water supplies (Voss, 2000). Voss attended University of California at Berkeley School of Law in 2001 and University of Utah in 1997. The authors is reliable because of the academic achievements he has earned prove he is educated and knows what he's doing but he might have some bias because of his direct affiliation with the Administration of Air and Water Resource and Solid Waste Management Programs and The Central and Southern Florida Project (C &
Groundwater is one of the most important natural resource in the nation, specifically in the Central Valley. In California, many people are pumping a lot more water because of the California drought and groundwater is a good resource for the farmers to harvest their crops. However, the main issue today is that in the Central Valley is that the land is sinking faster and faster due to the demand of pumping more water from the ground. The ground sinking in California isn’t recent, but it has been going an ongoing issue for over decades. Therefore, the land sinking has background history, but many studies and researchers didn 't take it as a warning until recently, and as a result it has been getting worse. The land sinking occurring in the Central Valley can cause damages to our communities such as bridges and roads cracking and can even go as far as cracking irrigation canals. These damages can cost millions of dollars to recover and rebuilding damages. On the other hand, the ground sinking has already destroyed canal linings, which will cost millions of dollars to repair. With that being the case, imagine all the other damages that the ground sinking will cause and cost to fix them. For these reasons, the state of California needs to start finding possible solutions to prevent the ground sinking from further sinking and to prevent more damages to the Central Valley. Solutions that might include encouraging the community to
It does affect us a lot not just me but my mother. We lived a place that have a lot of this pothole. One day my mother was drive to the park a lot in apartment and she pump to one those potholes in our park a lot. It did damage big to ours. Not just the car but she almost hit the car to a tree. It is scary things. I think effect a lot to the community because
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.).
“ A century ago Floridians thought their biggest problem was too much water where people wanted to settle. Now, our biggest problem is that we do not have enough water where people want to settle.” (Prologue pg. 10) Says Cynthia Barnett author of Mirage: Florida and the Vanishing Water of the Eastern U.S. 100 plus years ago Florida was drowning. We had more water than we knew what to do with. In Mirage it teaches us many of the ways that we have come so far from being this teeming state. Through wasteful water use, legal and political fights for control, overconsumption, and undervalue for one of the most vital elements of life we have put ourselves in a position that is showing to be very difficult for Florida to overcome. Florida has
Our topic is sinkholes. Sinkholes are holes that are formed in the ground from the underlay of rocks collapsing. The majority of sinkholes in the U.S. occur in Florida because the state is on top of carbonate rocks which are weak
Past development has left Lee County vulnerable to future hazards. All the planning in the world cannot address mother nature’s natural buffers to protect low-lying coastal areas. Builders throughout the state have created a primary concern for future hazards. Thus the reason for multiple agencies getting involved in the planning process in Lee County. The state of Florida highly suggest policies that limit expenditures in areas that have been impacted by past disaster events. This policy is the one policy that could have the most impact in areas like Lee County. The old saying goes, “when you keep doing the same thing over and over, you will get the same results.” By following the Local Mitigation Strategy (LMS) and stopping residents or builders from developing in the impacted areas will prevent the hazard from affecting the people in that area. Furthermore, having the goals in place will help Lee County manage the disaster events and maintain a system that protects the population from injury from future risk (Schwab,
