SUNWAC or, much less often used, SUNWACD is a mnemonic for the rivers which drain eastwards from the Pennines into the right bank of the River Ouse in Yorkshire. It stands for:
 * Swale draining Swaledale
 * Ure draining Wensleydale
 * Nidd draining Nidderdale
 * Wharfe draining Wharfedale
 * Aire draining Airedale
 * Calder draining Calderdale and flowing into the Colne
 * Don with the Dearne as a trbutary

The D is not usually included because it does not have an eponymous dale.
