Scope of study The overall aim of this study is to practice, shortcomings and future research needs in determining freshwater-flow.needs of estuaries. In particular, the study has examined the use of computational, including statistical, modelling in determining. these needs. It is hoped that. the resultingSdocuments will be of practical use across all disciplines working within estuaries. The outputs .fi-om-the study are: . an R and D Technical Report-that identifies shortcomings, best practice, implementation benefits and-future R and D of freshwater flow needs to.estuaries. . this quality control-manual to be used when undertaking a computational estuary model study.. This manual contains guidance on:-. . . . . how-to define modelling~projects; tender a modelling study; field data collection techniques; model types and quality control; modelling and data.collection strategy. The layout of the manual is shown below. It is hoped that this manual will pr0vide.a framework : for modelling.for the beginner, but will also provide information useful .for the experienced practitioner. Computational modelling The use of computational.models is one of the most powerful tools available to,quantify the. water .. effect of variations of freshwater. .residual flows when- applied -to estuarine quality/morphology-processes. The prolonged and detailed public enquiries that are likely to accompany. future applications to increase abstraction and reduce MRF in estuaries will require supportable evidence of the impact of increased abstraction. Any new national methodology must provide such quantified evidence. R and D -T and chnicalReport WI 68 ... 111 LAYOUT OF QUALITY CONTROL MANUAL There are two main types of modelling techniques available to test the effect of residual flows on the estuarine transport/residence processes: . . Statistical models are a relatively quick approach which are useful in initial studies to qualitatively assessthe effects of different MRFs on the estuary. Deterministic/hydrodynamic models use mathematical descriptions of physical laws and processes, and require detailed research and carefully designed field data. There is also a need for guidance on how reliable the model results should be, and what the most appropriate models are to answer specific queries or requirements for data. A system is needed to ensure that procedures are correctly followed and to check that the software is being correctly applied. This manual provides appropriate guidance in these areas.
