Early flood prevention Before, early flood protection includes straightening out creeks and padding them with concretes. While these creeks are remarkable for moving water in an instant, they are not really a scene you can appreciate.
And so now, various flood protection approaches were developed and they are not only scenic, but they also serve as a habitat for some animals. Natural Approach to Prevent Flood The water constituency balances the necessity to provide protection against flood with the requirement to protect natural resources.
There are a lot of factors that must be taken into consideration to determine the best way to enhance the capacity of the creeks for flood water while decreasing its impact to the bionetwork.
Here are some methods you could choose from:
2. Overflow channels
3. Bypass channels
The water district make use of different flood protection technologies that keep the creeks as beautiful and as natural as possible.
The goals of water district have kept swiftness with varying community values. New versatile flood protection methods safeguard properties while preserving habitation, enhancing water quality as well as giving creek side trails. Crib Walls One way to reinforce creek banks is to utilize crib walls – dead trees organized in a Lincoln-log manner. Once the logs are buried, natural vegetation can thrive. Eventually, the logs will rot, and the roots of the new planted shrubs and trees will in time, give protection from attrition.
Overflow Channels Another method to improve the capacity of creeks for flood waters is to construct an overflow channel that is parallel to the creek. Overflow channels are only utilized when the water flows at its utmost. In this manner, you don’t have to worry about the creek bed as well as the habitat of wildlife.
Bypass Channels Guadalupe River streams right through the inner city of San Jose and has caused a lot of damages that cost up to millions of dollars. To improve their protection from flood, bypass channels have been set up. However, you will not be able to see them because they are constructed underground. Once the river gets higher, water will start flowing through enormous culverts that stream under downtown streets.
These ducts redirects the superfluous water around the developed places of downtown, thus preventing flood from occurring.
