Cimanuk

The Cimanuk flows north through western Java to the Java Sea near Indramayu. Its estuary was known to Portuguese visitors as Chemano, a port on the eastern edge of the Sunda kingdom. In the early sixteenth century Tomé Pires described it as a boundary of that realm, whose other ports farther west carried pepper into the maritime trade. The river's changing mouths spread across the low coastal plain as it reaches the sea.
