Measuring hydrodynamics and sediment transport processes in the Dee Estuary

The capability of monitoring and prediction in the marine environment provides information that may allow sustainable development of coastal and offshore regions. Therefore, the continuous measurement of environmental processes becomes an important source of information. The present paper shows data collected during 6 years, and in particular during 2008, in the Dee Estuary. The aim of the data collection is to improve the observations of the mobile sediments in coastal areas and its forcing hydrodynamics and turbulence. Data includes information from the deployment of instrumented rigs measuring sediment in suspension, currents, waves, sea level, sediment size and bedforms as well as cruise work including grab sampling, CTD profiles and side-scan sonar. The data cover flood and ebb tides during spring and neap periods with moderate and mild wave events, thus, having a good coverage of the processes needed to improve knowledge of sediment transport and the parameterizations used in numerical modelling. The data, in raw and treated, are being banked at BODC (British Oceanographic Data Centre, http://www.bodc.ac.uk/) which is the formal British organization for looking after and distributing data concerning the marine environment.

The Coastal Trade of Connah's Quay in the Early Twentieth Century: A Preliminary Investigation

This chapter explores one of the few existing sources for coastal trade activity in ports - the trade records of Connah’s Quay on the River Dee between 1905 and 1914. It examines the port register, crew agreements, and the records of Wrexham, Mold and Connah’s Quay Railway, in attempt to determine the specific (as opposed to national or regional) factors that contributed to the decline of port activity in the run up to the First World War. These factors include the treacherous waters of the Dee Estuary; the absence of liner trade; the narrow range of goods; and the imbalance between outward and inward-going voyages. Through analysis of these factors, it concludes that Connah’s Quay was indeed atypical of the national trend in coastal shipping during this period.
