The term 'BANK RIVER' can be broken down into three crossword solutions: SEINE (5 letters), RIVE (4 letters), and LEVEE (5 letters). The SEINE is a major river in France, flowing through Paris and emptying into the English Channel. It is the second longest river in the country and has been an important waterway since ancient times. The RIVE is a tributary of the SEINE, located in the northern part of the country. It is a relatively short river, but it is still important for transportation and irrigation. Finally, a LEVEE is an embankment built along the banks of a river to prevent flooding. Levees are often constructed to protect cities and towns from flooding, and they are especially important in areas prone to flooding.
