How to model a weir

Dams are built to hold back a body of water either to give a head of water to drive machinery, to allow water transport or to prevent seasonal flooding.  They are used to create lakes, canals, mill ponds and reservoirs.  However, once the body of water behind the dam is full, dams do need to let some water through.  That’s normally via a weir.
