Simplify the following text for a Grade 7 native English-speaking person.
Original: TimiÅ oara has its name derived from the river TimiÅ meaning the fortress TimiÅ and the TimiÅ City , even though its name indicates it , is not settled on the river , but on another Romanian-Serbian river , Bega .
Simplified: Although , the name comes from the river , when about 800 years ago the region was a swampy one and the TimiÅ had a very large flow area . In 1728 when the rivers TimiÅ and Bega were canalized , TimiÅ stopped to flow through the city .
