At about to the northeast of Badia Tedalda, the river gets into the Emilia-Romagna region, in the Casteldelci "comune", province of Rimini. Then it flows through Ca 'Raffaello, an exclave of Badia Tedalda; to the north of here, the Senatello river flows into the Marecchia as a left tributary. Later, in "Ponte Masa", the Masa river flows from the right into the Marecchia.
