The Dommel is a stream in Belgium and the Netherlands, left tributary of the Dieze. It rises in north-eastern Belgium near Peer and flows into the southern part of the Netherlands. The Dommel takes in water from the Keersop, Tongelreep, Run, Gender and Kleine Dommel streams and merges at 's-Hertogenbosch with the Aa stream to form river Dieze, which subsequently flows towards the Meuse. The main cities and towns along the Dommel's course are Peer, Neerpelt, Valkenswaard, Dommelen, Eindhoven, Son en Breugel, Sint-Oedenrode, Boxtel, Sint-Michielsgestel and 's-Hertogenbosch. The most original part and natural state of the Dommel can be found between Eindhoven and Boxtel.
