Conference Paper
Beach and dune provide natural defense against erosion and flooding, and associated mitigation measures are classical coastal engineering problems studied by many researchers. Winter storms cause severe erosion leading to dune breaching and then flooding of the hinterland areas. Resiliency of a barrier beach depends on the ability of the dune (resi...
Conference Paper
Optimising the planning and management of reservoir systems by integrating multi-purpose objectives has been the subject of extensive research work since the 1990s, especially when the multiple benefits of reservoir system operation (e.g., supplying demand systems) and the reduction of natural risks (e.g., flood mitigation) are to be combined. The...

Despite the perceived value of DSS in informing environmental and natural resource management, DSS tools often fail to be adopted by intended end users. By drawing together the experience of a global group of EDSS developers, we have identified and assessed key challenges in EDSS development and offer recommendations to resolve them. Challenges rel...
Article
Water quality is an important factor to consider when attempting to reconcile mathematical optimisation modelling with the physical reality of water-resource systems. In particular, when the greater part of water resources in supply systems comes from artificial reservoirs, as in Mediterranean regions, a simplified approach based on the attribution...
Article
The definition of an effective link between drought indicators and drought mitigation measures in a regional water supply systems is a complex problem involving environmental, social and economical factors. The gap between research and practice in this field still limits the application of mathematical modelling tools more than institutional or tec...
