What are the three methods of flood control?

These methods include planting vegetation to retain excess water, terrace slopes to reduce slope flow, and building alluviums (man-made channels to divert water from flooding), construction of dykes, dams, reservoirs or holding tanks to store extra water during flood periods.

How does controlled flooding work?

Floods can be controlled by redirecting excess water to purpose-built canals or floodways, which in turn divert the water to temporary holding ponds or other bodies of water where there is a lower risk or impact to flooding.

How can we control river flooding?

Natural flood management Measures might include using small barriers in ditches and fields, or notches cut into embankments, to divert the water into open land. Letting pools form outside the main channel of a river means the water is temporarily removed from the main flow – reducing the power of the floodwaters.

How do you build flood control?

Some methods of flood control have been practiced since ancient times. These methods include planting vegetation to retain extra water, terracing hillsides to slow flow downhill, and the construction of floodways (man-made channels to divert floodwater).

How are floodplains managed in the state of Massachusetts?

What do you need to know about flood resistant construction?

In addition to the provisions found in the building code and Wetlands Protection Act, other flood-resistant construction requirements may be found in: FEMA’s Flood Insurance Rate Maps provide the minimum standards for delineated floodplains.
