Gays Mills was submerged five feet deep in water, buildings floated away at Boaz, and all six members of a family near Viroqua drowned when their farmhouse was swept downstream" ("Floods in Wisconsin," the Wisconsin Historical Society, 2009). As is illustrated by this anecdote, flooding is almost always devastating to the residents of an area -- many Wisconsin residents lost everything from the flooding that occurred. Ecologically, from a holistic perspective, flooding can have some benefits, by returning nutrients to the soil, opening up the land to new habitation by a variety of species and replenishing wetlands. Also from a long-term perspective, wetlands can receive runoff from higher areas affected by heavy rains.
Flooding also has historically worked to counteract the severity of droughts. However, one interesting component of Wisconsin's struggles is that while some areas of the state have suffered terrible floods, others have been afflicted by a lack of precipitation ("Effects of climate change in Wisconsin: Flooding in the south, drought in the north," Wisconsin Geologic History and Natural Survey, 2009). Current geographical and climate changes have been 'ill winds' that have brought few residents any 'good.'
It has been possible in some areas of the state to mitigate the effects of flooding. Coon County has been one notable exception to the intensifying patterns of flooding in the area. During the 1930s, agricultural practices were modified to mitigate flooding: the newly created Civilian Conservation Corps (CCC) increased the degree of land slope to divide land tracts of farmers. Relatively flat bottomland and land sloping from 2-20% were made into cropland or pasture. Slopes from 8% to20% were put into contour strips to protect the pasture. Then, "the 20-30% land was fenced for pasture by the CCC crews, and the steeper land was used for woods. These same guidelines were used on ridges to separate land use" ("Coon," Vernon County, 2009).
Later on, in one experiment, stream flow for 67 years was simulated mimicking conditions in the 1930s; conditions in the 1970s, excluding the modified areas, and conditions in the 1970s, after the CCC intervention. "These simulations showed that the changes in agricultural practices over 40 years (1940-80) reduced the 100-year flood by 53% (from 38,900 to 18,300 cubic feet per second)…Comparisons...
Flooding There are many natural hazards in the environment, but some of them are not as "natural" as they would appear. In other words, some of the environmental hazards in the environment have been created or enhanced by what human beings have done. Flooding is one of those issues, as humans have dammed up streams, moved rivers, and created their own lakes. They have also removed trees and graded land to
Flooding Mold Extreme Weather Mitigation Formulate a plan on how you would use clinical epidemiology to guide your options and actions on dealing with this issue. Scientists define flooding events by their probability of occurring in a given time period. For example, a hundred-year flood is a flood that would theoretically probable to occur only once every century. However, climate change and the changing atmospheric condition are predicted to increase the frequency of
Benefits -- Social media is a cost-effective and very powerful tool that will allow an easy two way exchange between public health professionals and the public in the event of a disaster. Since people often use their mobile device to hook up to social media, they would have access to information almost immediately, be up-to-date about the disaster or disease and even sent pictures and help governmental officials assess the
Natural Hazard, FEMA -- "Floods" Natural Hazard: Flooding Flooding, according to the Natural Disasters Association (2014), "is the most common environmental hazard worldwide." This according to the organization is more so the case given the vast distribution (geographical) of both low-lying coastal areas and river flood plains. Essentially, flooding occurs once an area that was not formerly underwater is submerged as a result of water overflow. According to Ready, a campaign that
However, the most horrible cases of flooding are a combination of storms, 'spring tides' and low atmospheric pressure (Think Quest). Effects of flooding: Flooding is very dangerous as floodwater severely disrupt both public and personal transport by cutting off roads and railway lines. It suspends all communication links by damaging the telephone lines and disrupts normal drainage systems in cities, while sewage spills are common, representing a serious health risk, along
Yellow River's Flooding History Flooding is the most common hydrological hazard occurring in various regions of the world. For instance, statistics have recorded 3000 such disasters since the beginning of the 20th century. This is attributed to the widespread distribution of rivers, floodplains, and low-lying coastal plains that are extremely attractive for human settlement. Occurrence of this hazard claims approximately twenty thousand lives each year: at least twenty million are displaced
