Flooding
As defined by USGS, flooding is a relatively high stream flow that overflows the natural or artificial banks of a stream or that submerges land not normally below water level, and, as a natural event, is caused in a variety of ways. Winter or spring rains, coupled with melting snows, can fill river basins too quickly. Torrential rains from decaying hurricanes or other tropical systems can also produce flooding. The excess water from snowmelt, rainfall, or storm surge accumulates and overflows onto lowlands, adjacent to rivers, lakes, and oceans which are subject to recurring floods; most commonly referred to as floodplains.
Currently, floodplains in the U.S. encompass over 16 million households. In the state of Kentucky, approximately 227,000 properties are within the 100-year floodplain and thus face a substantial risk of flooding.
Description
The USGS defines floods as “an overflow or inundation that comes from a river or other body of water and causes or threatens damage. Any relatively high streamflow overtopping the natural or artificial banks in any reach of a stream."
A floodplain is defined as the lowland and relatively flat areas adjoining rivers and streams. These areas carry excess flood water during rapid runoff.
FEMA requires municipalities to plan for a base flood, which is also referred to as the 100-year flood. The 100-year flood is an area in the floodplain that has a 1% chance of flooding in any given year. Flood frequencies, such as the 100-year flood, are determined by evaluating the size of all known floods for an area and determining how often floods of a particular size occur.
Flooding may not necessarily be directly attributed to a river, stream, or lake overflowing. Rather, it may simply be a combination of excessive rainfall or snowmelt, saturated ground, and inadequate drainage. FEMA has a broad classification of flood types:
Ground failure causes a few different forms of flooding. The main type is mudflows, or mud floods. Mud floods are often the result of rain falling on terrain that has been stripped by forest fires and brush fires and, thus, cannot retain the runoff water. Mud floods can cause more severe damage than clear water floods due to the force of the debris-filled water characteristic of them. Another ground failure related flood type is from subsidence. For the area, subsidence can lower ground levels around river banks and be caused by the karst topography or human activities such as mining, construction, or landscape.
Dam and Levee Failure Floods are caused by the structural failure of dams and levees or the design protection level being surpassed by flood waters.
River Floods are characterized by overflow of water from rivers or other similar bodies of water (streams, creeks, etc.) occurring over a period of time too long to be considered a flash flood.
Flash Floods are categorized as such for their timing and intensity. A flash flood occurs near instantly due to intense rainfall amounts in a relatively short period of time. Steep topography plays a very crucial role in an area’s proneness to flash floods.
Urban Floods are directly linked to urbanization and the materials associated with it. Impermeable, flat concert and asphalt causes water to settle and collect instead of absorb or runoff. Urban floods usually result in impassable roads and flooded basements.
Ice Jam Floods are similar to flash floods-the formation of a jam results in a rapid rise of water both at the point of the jam and upstream. The formation of ice jams depends on both the weather and the physical conditions in the river channel. Flooding due to ice jams (or other ice conditions) can occur at different times and in different ways.

Kentucky is at high risk for an increase in inland flooding. Over 30 states were assessed for their threat and preparedness levels and Kentucky was rated as having an average threat level. The threat will be raised to above average by 2050 due to the lack of progress in Kentucky for preparedness, resiliency, and mitigation. More than 160,000 people in Kentucky are living in areas at risk for flooding, including a large portion of the BRADD region.
There has been an increase in precipitation intensity and frequency that is projected to continue to increase. This can lead to flooding especially in urban areas where more runoff can occur from impervious surfaces like roads and parking lots.
Potential impacts include:
There has been an increase in precipitation intensity and frequency that is projected to continue to increase. This can lead to flooding especially in urban areas where more runoff can occur from impervious surfaces like roads and parking lots.
Potential impacts include:
- Property damage
- Displacement
- Loss of life
- Deterioration of infrastructure (stormwater and sanitation systems, transportation)
- Water quality degradation
- Traffic and road closures
- Impact on economy: agriculture, industry, tourism, and natural resource management
Extent
For hazard mitigation planning purposes, the extent or the scale of flooding is measured in depth of flooding. To find records of past flood depth by jurisdiction, BRADD used stream gage data, NCEI narratives, and local newspaper articles to identify extent.
Please note that because the cities in the BRADD region have low populations and occupy small portions of each county’s overall acreage, the county is the predominant actor for mitigation efforts. Therefore, in cities where the depth data is not available, the depth data that correlates to the County, also applies to the city.

NOAA Flooding & Flash Flood Events
When looking at flooding events by jurisdiction, there have been no historic occurrences of flooding and flash-flooding in Adairville in Logan County or Woodburn in Warren County.
NFIP & Impact
Flood risk can occur at any time of year; however flooding in the BRADD region is most often the result of heavy rainfall, therefore the spring and summer months have the greatest potential to produce flooding events. Further, warning times before flooding events depend upon the type of even and range from minutes to hours in the cases of flash flooding, to several hours/days in the case of out-of-bank flooding, to 3-5 days for river flooding.
Potential Impacts:
Built Environment
Flooding can cause structural damage to both residential and commercial buildings and destroy furnishing and inventory.
Flooding will causes inconvenience or stoppage to many system. Transportation systems such as roads and railways become unpassable. Large amounts of water from a flood can affect water management systems such as the backup or hiatus of drainage, sanitary, and sewer systems. As heavy rains persist during a flood event, excess water drains into the ground water system. This causes the water table to rise and cause further ground water floods. If chemicals are mixed with flood waters, this can contaminate the ground water, a common source of fresh water for communities.

Natural Environment
As flood waters engulf the surrounding natural environment, they are saturated with chemicals and other substances associated with the manmade environment that they have also been in contact with. As these abnormal waters settle and flows through natural ecosystems they can alter and even destroy both plant and animal life. When the flow of flood waters becomes so immense, it can physically destroy or uproot naturally growing vegetation and also drive specific species of animals out of their natural habitats for good.

People
People with property located in the floodplain or within areas subject to seepage are vulnerable to flooding. Stoppage to transportation systems can make it very difficult for isolated populations to receive aid or escape breeching flood waters. Vulnerable populations, such as the elderly or people who need medical attention, may be temporarily cut off from accessing life-saving resources.
Economy
Floods can affect local economies by disrupting transportation systems needed for people to get to and from work and destroying places of business and means of production. When flooding occurs in more rural areas, livestock and agricultural system will be affected. Crops can be destroyed in the growing season, or prevent from seeding in the off season. Large insurance payouts to residents or business owners who have procured flood insurance might also have an economic impact.
