Most mountainous areas experience relatively consistent snowfall totals from year to year, but an unusually heavy winter of precipitation can spell bad news for low-lying areas around the mountains when spring hits.
The good news is that sustained winter precipitation provides a long lead time to prepare for potential flooding. These are just a few examples of common causes of floods, but there does not need to be an incredible weather event for you to experience flooding at your home.
When you have an urban drainage basin that is made of concrete, there is no ground for water to sink into.
So, when those drainage basins fill up, it is going to mean flooding for low-lying areas.
While we have come to depend on 20th-century architecture, and much of it does its job well, there is always a possibility that a structure will fail.
Many of our cities are made of mostly concrete and other impermeable material.The flood situation is the biggest news in Thailand. Natural calamities like earthquakes, avalanche volcanoes floods, etc. Floods are common natural disasters that can affect millions of people around the world.

When it rains heavily, however, those systems are overwhelmed, and that water doesn’t drain nearly as quickly as it needs to.In short, the drainage systems back up, and the water rises — sometimes into homes.When there is a lack of vegetation, however, there is little to stop water from running off. While area residents likely welcome the rain, the lack of vegetation after the drought can cause flash flooding.This does not always happen given that basins and reservoirs are close to empty, but it can occur in cases of extreme rains following long periods of drought.Flooding is experienced all over the globe and for a variety of reasons — but why exactly does flooding occur?There are several human causes of flooding, including poorly designed infrastructure. Here are eight of the most common causes of flooding, both natural and human-induced. The simplest explanation for flooding is heavy rains.This is part of what happened after Hurricane Katrina hit New Orleans in 2005.Levees failed and made the flooding far worse than it would have been otherwise.
