Abstract

Hydroinformatics tools are increasingly being used for predicting hydrodynamic, hydrological, and water quality processes in river and estuarine waters. The numerical solutions of the governing hydrodynamic and solute and sediment transport equations form the basis of these software tools. Details are given herein of the governing equations for three-, two- and one-dimensional flow-field predictions and the transport of water quality indicators and sediment transport processes within the water column. Two case studies are then discussed. In the first of these studies linked 1-D and 2-D models are used to predict the velocity and fecal coliform distributions for a relatively large river and estuarine system, including the Ribble Estuary, its tributaries, and the Fylde coast. In the second of these studies, the velocity, suspended sediment, and heavy metal concentration distributions are predicted along the Humber Estuary using 2-D and 3-D models, with dynamic partitioning coefficients being used to link the metal concentrations and sediments. Details are also given of the hydrological models used to specify the pollutant discharge loads from land used models.
