Final Project

  1. 1. POTENTIAL FOR STORMS AND HAZARDS IN KENTUCKY Sara Ferguson and Kevin Armstrong
  2. 2. FLOODS AS A HAZARDS <ul><li>Floods have been identified as the most common hazard to Kentucky </li></ul><ul><li>There are 2 types of flooding in KY: Flash and River Basin </li></ul><ul><li>It is most dominant in the East where the mountains are </li></ul>Covington, KY 1937 Flood
  3. 3. FLOODS AS A HAZARDS <ul><li>The IPCC along with the UK Hadley climate model predict precipitation increases in Kentucky up to 10% in the Winter. It predicts a possible increase of 20% in the Spring and Fall, and a range of 10-50% in the Summer. </li></ul>Source: US Global Change Research Program Hadley Centre Scenarios
  4. 5. TORNADOS AS A HAZARD <ul><li>Any part of the state is vulnerable </li></ul><ul><li>The seem to have become more frequent (appendix) </li></ul><ul><li>The amount of damage they have caused have been on the rise as well </li></ul>1974 Richmond, KY
  5. 6. STRAIGHT-LINE WINDS AS A HAZARD <ul><li>A microburst is a downward rush of wind released from a thundercloud. It spreads horizontally and its damaging effects can be as bad as tornados. </li></ul>
  6. 8. DROUGHT AS A HAZARD <ul><li>The surface water from the Ohio River and its tributaries (that includes the Green River) supply most of the state’s water. </li></ul><ul><li>If there is less precipitation, there is a shortage of water from the reservoirs as well. In particular, Franklin and Lexington would be most effected from the Kentucky River ( </li></ul>
  7. 9.
  8. 10. HURRICANE REMNANTS AS A HAZARD <ul><li>Although we do not live within a hurricane zone, we are still effected by them. </li></ul><ul><li>The hurricane’s cyclones that pass through the state northeasterly can create heavy amount of rainfall, resulting in potential flooding </li></ul><ul><li>An example of its damage can be seen in 1965 when there were a huge amount of Tornados </li></ul>
  9. 11. WINTER STORMS AS A HAZARD <ul><li>Kentucky rarely is effected by snow storms due to our mild, temperate climate. </li></ul><ul><li>If our climate was to change, the amount of snow storms could also change </li></ul>
  10. 12. FOREST FIRES AND WILD FIRES <ul><li>The densely wooded eastern part of the state can burn in dry hot times. </li></ul><ul><li>Prime times for fires are the spring and fall. </li></ul><ul><li>There has been no major fires (greater than 5,000 acres) in the past decade. </li></ul>
  11. 13. SUBSIDENCE AND KARSTS TOPOGRAPHY <ul><li>55% of Kentucky is underlain by some type of karsts geology. </li></ul><ul><li>Even in good times the ground under our feet in Bowling Green is melting away. </li></ul><ul><li>Sinkhole collapse is initiated by heavy rain events. This causes transportation hazards and damage to property. </li></ul>
  12. 14. <ul><li>Many sinkholes are spurred on by human activities such as poorly planned engineering projects, the Dishman lane collapse was caused by improper drainage below the impermeable asphalt. </li></ul>
  13. 15. As flood events increase so does erosion and mudslides! <ul><li>With warming comes less frequent but more intense storm events, resulting in worse floods and dryer droughts. </li></ul><ul><li>Between 1985 and 1999 4,421 mountain tops were removed and valleys filled in eastern KY. </li></ul><ul><li>This practice has been shown to increase peak flow by 36% </li></ul>
  14. 16. DROUGHTS AND HEAT WAVES <ul><li>Every summer heat intensifies and rainfall decreases, severely impacting agriculture. </li></ul><ul><li>Urban heat islands exacerbate the effects on the elderly and weaker. </li></ul><ul><li>Many major metropolitan cities such as Cincinatti experienced a five fold increase in heat related deaths from the 80’s to the 90’s </li></ul>
