The River Severn is the main river that flows into the Bristol Channel.
A levee is an embankment that helps protect the land from a floodplain. A levee is formed when floodwater deposits material on the banks of a river, which builds up over time. The embankment slowly erodes away which is making rivers and streams wider and it can sometimes create a v-shaped valley.
Three rivers that flow into the English Channel are the Thames River, Seine River, and the Rhine River. The Thames is in England, while the Seine and Rhine are in the European Continent.
The Seine River empties into the English Channel.
The River Seine is the main one. the one used most in crosswords is the River Somme
An embankment could mean a raised bank along a river as part of flood defences.
Levee
A levee is a buildup of sediment deposited along the channel of a river that keeps the river inside its banks. It acts as a natural barrier that prevents the river from overflowing and causing flooding in surrounding areas.
Other rivers and streams add up into it and flow with the Mississippi River
There are multiple rivers that flow in France. One such is the Rhine River and another is the Channel River.
