Buried valleys are a common feature of the North Sea Region. Although invisible to the non-expert they serve as vital fresh water reservoirs and are therefore a classic example of the need for good information and professional input in planning processes if problems are to be avoided.

The water systems of which such valleys form a part are insufficiently understood at present. Water flows along buried valleys just as it does in normal valleys and this represents a risk of contamination that has rarely been considered in the past but the unique properties of buried valleys need to be further studied to prevent such risks.
