This document, comprising a collection of Worked Examples, is Volume II of the report on small source protection zone delineation. Volume I of the series contains a review of available methodologies and existing practice, while Volume III contains a selection of predefined WHPA capture zone approximations. Ultimately, the recommended methods only provide approximations to the correct solution, and properly documented local knowledge may be just as useful. In any event, the techniques should not be used in isolation, for the purpose of such modelling is to provide insight and not numbers. It is no substitute for informed professional judgement, but rather should be used to provide a framework upon which to test ideas about the flow characteristics in the vicinity of specific sources.
