What is a Flood: Floods are created by heavy or steady rain over several hours of days. Ground becomes saturated with water, forcing excess water to run off into the lowest lying point in the area. Water outlets, canals, creeks, streams, rivers, reservoirs and lakes will be inundated with water run-off causing swelling and excessive runoff into public access locations. A flash flood is caused by rapidly rising water along a stream or low lying location. There are four types of floods that you should prepare for (depending on your location), Tidal waves, river flooding, lowland flooding and flash floods.
Location: Coast lines or nearby ocean; Tidal waves. Flat planes surrounding large rivers; River Flooding. Area 1-2 feet below the surrounding plain; lowland flooding. Location is by relatively narrow canyons or valleys the descent from nearby mountains; Flash Floods.
Duration: Floods can take as little as 1 hour to being flooding chain, Most often hours of rain will begin a chain of severe flooding events. You have seconds to respond to flash flooding events.
Caveat: Stay out of direct flow areas. Nighttime travel escalates risk of emergency situations due to lack of light to properly see where water swelling has expanded. Never underestimate the swiftness of water flow. Flooding is strong enough to carry a semi truck down river at 30-50 miles per hour, in less than 2-3 feet of water! Fooding will wash out septic tanks and sewer systems. It is important to have a mobile water filter to filter and purify all contaminated water for hygiene and drinking purposes.
