Updated Abraham solvation parameters for polychlorinated biphenyls
An updated set of PCB solvation parameters was derived from four PCB properties and associated Abraham solvation equations.
Model error prediction using neural networks combined with chaos theory
This paper presents a time series prediction scheme using time-delay neural networks combined with chaos theory. To achieve reliable multi-step-ahead prediction, the optimal architecture of networks is determined by average mutual information and false nearest neighbours analyses in chaos theory. The resulted networks are applied to predict the model errors at 4 tidal stations in the Singapore Regional Model domain, with 5 prediction horizons ranging from 2 hours to 96 hours.
Free slip plane analysis of a strip footing using a genetic algorithm
A strip footing is a uniform load with infinite length in the third dimension. The safety of sucha load has been subject of investigation for a quite a long time. By ignoring the weight and internal friction ofthe soil, a number of upper- and lower bounds can be derived for the bearing capacity. This paper presents anupper bound method that gives the same result as the lower bound. In other words, the exact bearing capacityis derived. Even though the algorithm used is presented on a basic case, any geometry and subsoil configuration can be analyzed.
The Rhine delta : a record of sediment trapping over time scales from millennia to decades
Dissolved organic nitrogen dynamics in the North Sea : a time series analysis (1995-2005)
Dissolved organic nitrogen (DON) dynamics in the North Sea was explored by means of long-term time series of nitrogen parameters from the Dutch national monitoring program. Generally, the data quality was good with little missing data points. Different imputation methods were used to verify the robustness of the patterns against these missing data. No long-term trends in DON concentrations were found over the sampling period (1995e2005).
Coastal bio-geomorphology modeling : linking processes and scales
Application of bioassays in toxicological hazard, risk and impact assessments of dredged sediments
Exploring high-end scenarios for local sea level rise to develop flood protection strategies for a low-lying delta - the Netherlands as an example
The Veerman commission used scenarios for sea level rise, storm surges and river discharge as boundary conditions in their report "samen werken met water". This paper describes how these scenarios were developed.
Evaluation of two precipitation data sets for the Rhine River using streamflow simulations
This paper presents an extended version of awidely used precipitation data set and evaluates it along with a recently released precipitation data set, using streamflow simulations.
Operational modelling applications for coastal engineering : new developments
This paper describes three different ongoing developments andapplications of operational coastal modelling systems: 1) The development of an operational model to simulate storm impact along the Dutch and Emilia-Romagna coast 2) The application of operational modelling to predict bathing water quality along the Emilia-Romagna coast (Adriatic Sea, Italy)3) Ongoing developments of operational models into enhance the safety of swimmers.
