In the USA, 50 years ago the Army Corps of Engineers probably would have built a levee lining the estuary to prevent the water from flowing into the swamp so that the land behind the levee could be used for agriculture or developed for housing. The "channelization" the Mississippi River has caused higher floods even when there is less volume of water.
It is better to leave wetlands in the natural state, and to allow flood waters to flow into land that accommodates the high water times, other than to protect already populated areas, where people built in the flood plain before people and government had the wisdom to leave flood plains in their natural state.
Today is Sunday, so we have new photos on our Viva la Voyage travel photo site. This week we are showing some photos of the menthol blue waters of the Colorado River at the bottom of the Grand Canyon.
