Howard County Flood Analysis

1. The reasons why some buildings are in the floodplains is because of agricultural industry. Another reason is population growth and expansion into those areas where people felt safe because of improvements of levees. Even though people were told about the dangers most people relied on disaster insurance instead of flood insurance. There should be laws that prohibit further development of these areas because it is costing the taxpayers lots of money for people that want to live in these areas that know the risks. If there were laws in place they could use some of the land as soccer fields and football fields as overflow ponds if they do want to build in a floodplain they need to raise the ground up by hauling in soils that will let the water pass through into those overfill ponds.

The tendency towards more intense precipitation events is projected to the future. The more precipitation, the more risk of flooding.More heavy downpours may increase the likelihood of property damage, travel delays and disruption in

On August 19th 1955 the state of Connecticut was flood that filled many of the valleys causing approximately $185.5million in damages and 87 fatalities. The flood was caused by two back to back hurricanes rains from Hurricane Connie and Diane that totaled from 13 to 30 inches of rainfall within a 24 hour period. The Naugatuck River, the Farmington River, the Quinebaug River, Mad and Still Rivers were hit the hardest destroying 563 homes, the majority of which were located in lower Naugatuck Valley and Beacon Falls. Since this great flood many new ways to control this situation have been developed and put in place, such as many damns but by the Army Corps, to protect the surrounding towns.

Most people wouldn’t pay any mind to care about coastal resilience and the sea-level rise in the Tidewater area of Virginia. However, they are very important to the community and its development. In the past I was one of those people as well until I knew how much the Tidewater area could be affected by an extreme weather storm or pipe malfunction. Growing up in Virginia Beach I've always questioned why the houses in Virginia didn’t have basements. Because Virginia's elevation is approximately 5,729 feet, the average elevation is 12 feet above sea level, it's considered below sea level. The Tidewater area in Virginia is known for flooding when there are rain storms or other serious weather conditions as well. This is not only because of Virginia's elevation level, but also because of the sewage and waste system.

In the Washington DC area, it is not at all uncommon to see flash flood warnings scroll across the television screen, but nothing comes of it other than some rain. This past weekend, however, during Memorial Day weekend, Ellicott City, Maryland, which sits just outside of the beltway, experienced a horrible flash flood. The death toll still has yet to be announced, as cleanup and the search for survivors has just begun. Two waves of intense flooding hit the town unexpectedly, and with little warning. The town is a quaint little area with cute shops and storefronts, which sits in a valley, and the main street cuts a swath between two higher vistas. Several storms had been forecast earlier that day, and heavy rain was expected, but no one could have predicted such devastation, in such a short amount of time. This is the second massive flash flood to hit this area in as many years, leaving business owners, and residents alike, stunned and heartbroken.

One major factor to consider regarding future development in Andrews is its potential to flood, since landowners in higher risk areas for flooding would have to purchase flood insurance and prepare for a flood. Since a catastrophic flood event could destroy properties and infrastructure, as well as hurt the local economy, there are areas known as Special Flood Hazard Areas,

During the Autumn/Winter of 2013/14, an unusually high frequency of depressions moved across the Somerset Levels, causing both fluvial and pluvial flooding on a prodigious scale. The two main rivers which flow through the Levels (River Tone/Parrett), burst their banks, spilling into the already heavily saturated flood plain. An emergency was declared and subsequently allowed the Somerset council to request financial and physical aid to the region. This essay highlights the key reasons the Somerset Levels flooded, as well evaluating the main management solutions that were put forward during the peak of the flooding.

The Community of South Amboy appears to be supported of future mitigation efforts, in order to reduce flooding in the area; however, they don’t know who to contact in order to assist with the mitigation efforts The community of South Amboy could benefit from reducing the floods in the area, because insurance premiums will decrease, business and job opportunities will increase in the city of South Amboy. The lack of knowledge an organization could be a major roadblock for the community of South Amboy; however, the city’s emergency manager can assist in educating and organizing the community in order to create and implement mitigation plans in the

Anne Arundel County is located on the coast of Maryland, and is “ almost completely surrounded by tidal and non-tidal waterways.”(pg. 1) This plan assesses the vulnerability of Anne Arundel County to sea level rise and makes recommendations improving the community’s climate resilience. It analyzes the impact sea level rise will have on the county in two scenarios, one where sea level rise is 0-2ft and one where it is 0-5ft. For instance, it identifies that 371 county archeological sites are vulnerable to 0-2ft of inundation and 422 sites are with 0-5ft of inundation. The plan notes that such sites are important cultural resources for the county and that “[o]nce they are destroyed [...] the information these sites can tell us of our past is

In regards to flood hazards, most of the area seems to be safe. Figure 1 which showcases flood hazards in my area, illustrates that there are predominantly zones where no base flood elevations have been determined as well as areas that are outside the 0.2% annual chance floodplain. My home area as well as the nearby areas, are not around too many great areas of water but can be affected by maybe

5- In recent years, it is now clear that building suburban housing developments in floodplains in parts of our country has led to extensive and widespread flooding and economic disaster.

Additional factors that can contribute to flooding include: storms, global warming, the capacity, amount, length and spread of rain over a particular area, the size of waterway to hold excess water, the catchment and climate conditions preceding rainfall, ground cover, topography and tidal impacts.

The purpose of this report is to geologically evaluate the potential hazards for flooding in Hazard City. This report will include a detailed historic and extrapolated Stream Gauge Data Worksheet, as well as a graph of the Discharge Frequency Curve expected on Clearwater River. The report will provide Hazard city with my scientific analysis, conclusions, and provide recommendations concerning potential flood damages.

Between 12 and 14 inches of rain fell over a four-hour period in the mountains around the resort town of Estes Park. Unusual weather patterns allowed the huge storm system to stall over the area as it dumped its load. Which caused the river to overflow its banks.

Potential risk of flood from the river can be seen in the figure below for 1% or more annual probability floods. Maximum risk of property is at Plymouth and its surrounding areas where Horrabridge is also included. 1,510 approx. properties are in danger. There is risk of surface water flooding which due to environmental factors increasing day by day. (Cresswell, June 2012)
