Insurance Study: Guidelines and Specifications for Study Contractors, FEMA-37, 1995.

Answer It can accelerate erosion on properties at the end of the wall.
,What are the five main causes of flood damage? - Answer 1. Hydrodynamic forces
2. Debris impact
3. Hydrostatic forces
4. Soaking
5. Sediments and contaminants
Standing water as little as _____ feet deep can collapse the walls of a frame house. - Answer 3 feet

Are plants and animals the only beneficiaries of the "natural and beneficial functions" of floodplains? -
Answer No. People benefit from floodplains through the food they provide, the recreational
opportunities they afford, and the scientific knowledge gained in studying them. Floodplains also
recharge groundwater supplies and their filtering actions help improve water quality.
What does filling in a floodplain do? - Answer Filling reduces the floodplain's ability to store excess
water, sending more water downstream and causing floods to rise to higher levels.
Does moving sand and sand dunes affect flooding? - Answer Yes, it may remove a natural barrier that
protects inland properties.
1. Hydrodynamic forces are caused by _______ water and hydrostatic forces are caused by _______
water. - Answer Moving, standing
