Spill assessment and operational modelling techniques
About Dr. Frank Kleissen
With a Master degree in chemical engineering and PhD in Environmental Systems Analysis, Dr Kleissen’s main area of expertise is the use of mathematical models from a data perspective, including time-series analysis, model calibration, validation and application. He has also gained experience in Environmental Assessments, related to aquatic issues, hydrodynamic and water quality modelling (various dimensions) of marine, estuarine and freshwater systems (including groundwater). He has specialised in the effects of intake/outfalls (power stations, desalination, sewage treatment) and oil pollution modelling (fate of spilled oil) and risk assessment. He was instrumental in the development of the in the Netherlands accepted discharge test and the development of the European Guidance document on Mixing Zones.
Modelling plays an important role in assessing effects of spills, such as oil and chemical spills, not only short term but also long term. The presentation will discuss what is needed to be able to use these models within assessments (for planning/permits etc) and how can they be used for short term operational forecasting. The presentation will address model setup/validation/calibration/accuracy, data requirements and how these model systems can be used to deliver the information that is needed.
