Yes, floodplains typically build up at the mouths of streams because they are flat areas that receive sediment deposits carried by flowing water during floods. These deposits gradually accumulate over time, creating fertile land that is prone to flooding but also supports diverse ecosystems.
The broad flat valley floors that are carved out by wondering streams are called flood plain and the two methods of the streams eroding the rocks to form the flood plain are down cutting and lateral erosion.
Flood plains typically deposit fine-grained sediment such as silt, clay, and fine sand. These sediments are carried by the moving water during flooding and are eventually deposited along the flood plains as the flood waters recede.
Explanation :Flood plains are good farming areas because that's where the most fertile land is. Its constantly replenished with fresh silt washed down in a flood.-Timir SarkerSchool #5
Limiting development on flood plains is effective because it can reduce the risk of flooding, protect natural habitats, and safeguard human lives and property from potential damage. It allows for the natural absorption and slowing down of flood waters, minimizing the impact of flooding events.
An alluvial plain is periodically flooded by its river (it is a flood plain) and therefore any buildings built on it will likely be periodically inundated. This in itself does not make it unsuitable to build on but residential housing would either have to be built on stilts or flood prevention measures would be required on the river (not good for the environment). Further alluvial ground is only poorly consolidated and deep pilings will be needed to ensure buildings are stable. One must also take account that if the area is subject to earthquakes alluvial plains are likely to shake more and the ground may turn to quicksand. Finally alluvial planes are frequently sources of precious mineral material (sand and gravel) and if you build over this you prevent the deposits from being used. Thus overall alluvial plains are not suitable to build on.
Often, flood plains are where the most fertile soil is. The rich alluvial soil washes down from mountains in rivers and streams, bringing with it rich nutrients which are perfect for growing crops. Flood plains, being close to rivers, also offer easy transportation of goods up and down waterways.

Yes, there are flood plains in Canada.

Flood Plains National Park was created in 1984.
These flood plains are often seen merging with meander plains with hardly any difference so that it is difficult to distinguish between meanders and cover flood plains. These plains are formed only because of variation in speed and decomposition.

Theres not much you can do. You can build flood barriers, storm drains, anything you like. But the best thing that can be done is to retreat to high ground or quit building houses on natural flood plains.
No, Venus does not have flood plains like those found on Earth. The extreme temperatures and atmospheric pressure on Venus make the presence of liquid water unlikely, thus eliminating the formation of flood plains.
