Flood Control, Part 1: Building Barriers

 
We saw last week how floods happen. Now let’s take a look at the major methods of flood control.

Barriers are the first thing people instinctively turn to when they see a flood, no matter what its size.

For 5,000 years, we have been raising permanent or temporary barriers to manage areal, coastal, or riverine flooding that’s extensive enough to endanger homes, property, and lives.

And then there are those among us who stand on the seashore, looking out over the ocean and thinking, “What a waste of really good land…”
 



(Note: I don’t know who Ernest Kleinberg was, but this 30-minute 1950s or 1960s film is both informative and enjoyable to watch.)

Next week, we’ll look at how people manage rivers to control flooding. Then we’ll wrap up this three-part series with brief looks at how flooding is managed in Dhaka, Bangladesh; Jackson, Mississippi; and London, England.

About BJ Deming

After getting an associate's degree in forestry, I studied geology as an undergraduate back in the 1980s but went into medical transcription instead. It just worked out better for me. The Internet renewed my interest in geoscience as a hobby, and when I retired in 2014, I decided to write a book about cat evolution. That started a new career for me (enormous fun but not self-supporting yet). Right now, besides blogging I am finishing up the first two books in a self-published ebook series about the cat family and its history. Thanks for your interest!
