Tier 1. Conclusions

Following the scoping study you will have information about your catchment; either one or two estimates of your mean flow and an estimate of a low flow. This may be fed into the other aspects of the assessment to determine the feasibility of the scheme.

At this point there is very likely to be considerable uncertainty associated with the estimates of both mean and low flows and this should be taken into account within the assessment. As a general rule of thumb the uncertainty may be halved through proceeding to the next tier.
