The main activity of the CRC for Catchment Hydrology is cooperative research. With this cooperation taking place between all of its industry and research parties, the CRC is well placed to produce outcomes from its core research projects that meet industry needs and lead to improved catchment and land management. For its major projects, the strategy is to create new knowledge in priority research areas, and use the interaction between industry and research available in the CRC to facilitate its adoption.

"Hydrological Recipes" is an example of another kind of cooperative activity encouraged by the CRC structure. It has involved both industry and research staff in identifying the needs of industry that could be met (primarily) from existing knowledge. Here we are talking about procedures that were not well known, were in a form that wasn't easy to understand, or simply had been developed but not documented. Doubtless, there are plenty of other recipes to add to this initial batch, so an update or sequel is contemplated.

Many people have contributed to this first edition of "Hydrologic Recipes"; without their knowledge, ideas, enthusiasm, and energy, we couldn't have made the concept a reality. The goal of putting ideas in a form useful to the profession and sharing them is one which has been a feature of the short history of modern hydrology; the production of "Recipes" shows that we plan to continue this practice in the CRC for Catchment Hydrology.
