2013Williams BJ, Cole B, 'Mining monitored data for decision-making with a Bayesian network model', Ecological Modelling, 249 26-36 (2013) [C1]

A Bayesian network model of Anabaena blooms in Grahamstown Dam, near Newcastle, Australia is described. This model meets the criteria of being decision-focused, data driven, transparent, and capable of being used by non-expert modellers. Monitored data were arranged in a consistently formatted database from which the model could 'learn' probabilistic relationships between model elements such as pumped nutrient load, lake water column nutrient concentrations, and Anabaena concentrations. This 'minimal model' produced useful insights into ecosystem relationships and provided a basic model for later development. Subsequent modelling and elicitation of conditional probabilities from experts strengthened components of the model for which there is little data available. The approach to incorporating elicited data is described and some simple scenario testing is also presented. Management outcomes resulting from application of the model are presented. © 2012 Elsevier B.V.

Characteristic schemes for the solution of the Saint Venant equations for unsteady flow in a fixed-bed prismatic open channel without lateral inflow were examined. The study was restricted to schemes using a fixed spatial grid requiring interpolation between the characteristics and the grid. Five solution techniques which differed in their interpolation procedure and order of finite difference approximation were developed. The accuracy of the water level and flow rate predicted by each solution technique for different grid spacings were compared and mass balances were computed for each technique.
