Preference based decision support system for Waelpolder: An a priori design optimization approach (PDOA) as decision support system, applied to the urban development of Waelpolder

Negotiations in urban development projects can take a long time, going back and forward to the designer many times, even leading to stalemate situations. Requirements can be set intuitively, without knowing what the side effects of the constraints will be for the urban development. On top of that, approval of all stakeholders is needed to be...

Optimal Rehabilitation of Urban Drainage Systems: Application of single-objective optimisation for the implementation of Green-Blue-Grey Infrastructures in changing climate

Urban Drainage Systems (UDS) are one of the most vital yet, complex infrastructures that support people's livelihood in urban areas. However, due to their mainly underground infrastructure and complexity, the planning and management of UDS are usually associated with high investment, which stakeholders sometimes overlook. As long-lived...

Seakeeping Analysis and Hull Optimisation on Wet Deck Slamming of Fast Ferry Catamarans

The present research performed a design exploration of fast ferry catamarans with hard chined demihulls sailing in irregular head waves, to analyse the influence of the demihull shape (without appendages) on wet deck slamming, and identify the geometrical properties and their trends to reduce it. Wet deck slamming is a phenomenon known to cause...

Performance Assessment of Global Optimization Algorithms in Automatic Calibration of Groundwater Models

Calibration of groundwater models can be done manually by comparing the measured and computed groundwater heads or automatically using algorithms which do the work for you. Modules for this purpose are included in or linked externally to traditional groundwater modelling software and used. One such module PEST (Parameter ESTimation) uses the...
