Introduction
My key research interests concern issues relating to geoinformatics and remote sensing as applied to emergency management, resilience of societies and critical infrastructures, critical infrastructure protection, civil protection, urban resilience, (volunteered) geographical data analysis, spatial data analysis, environmental changes and risk. I developed a fast and accurate socio-economic damage and risk assessment tool, called FLIAT, which models and estimates the impact, and the societal collapse due to a flood event, and which will provide guidance for evacuation in the future.

Conference Paper
Full-text available
Without adaptation, 0.2 to 4.6% of the global population may be flooded annually in 2100 with scenarios of 0.25 till 1.23 m global mean sea level rise. Therefore, it is necessary that local governments engage and educate the local community in order to adapt to the impacts of sea level rise. To this point, we developed a comprehensive four-dimensio...
Article
Full-text available
Low elevation coastal areas are vulnerable to the effects of sea level rise and to an increase in the frequency and severity of storm surge events due to climate change. Coastal urban areas are at risk because coastal flooding causes extensive damage to energy and transportation infrastructure, disruptions to the delivery of services, devastating t...
Article
Full-text available
Floods cause major disruptions to energy supply and transportation facilities and lead to significant impacts on the society, economy, and environment. As a result, there is a compelling need for resilience and adaptation against extreme flood events under a changing climate. An accurate focal priority analysis of how societies can adapt to these c...
Article
Full-text available
Floods can cause damage to transportation and energy infrastructure, disrupt the delivery of services, and take a toll on public health, sometimes even causing significant loss of life. Although scientists widely stress the compelling need for resilience against extreme events under a changing climate, tools for dealing with expected hazards lag be...
Article
Full-text available
Worldwide, flood events frequently have a dramatic impact on urban societies. Time is key during a flood event in order to evacuate vulnerable people at risk, minimize the socioeconomic , ecologic and cultural impact of the event and restore a society from this hazard as quickly as possible. Therefore, detecting a flood in near real-time and assess...
Conference Paper
Full-text available
There are many sensors and measuring methods for detecting moving objects, each with its advantages and disadvantages. In active tracking methods (based on e.g. GNSS technology), the user is informed and actively participates, for instance by installing a smartphone app. These methods typically have the problem that only a limited part of the movin...
Thesis

Floods can cause damage to transportation and energy infrastructure, disrupt the delivery of services, and take a toll on public health, sometimes even causing loss of life. Although scientists widely stress the compelling need for resilience against extreme events under a changing climate, tools for dealing with expected hazards lag behind. Not on...
Article
Full-text available
Increasing urbanisation, changes in land use (e.g., more impervious area) and climate change have all led to an increasing frequency and severity of flood events and increased socio-economic impact. In order to deploy an urban flood disaster and risk management system, it is necessary to know what the consequences of a specific urban flood event ar...
Poster
Full-text available
The flood impact assessment tool is developed to calculate the socio-economic impact due to floods. An analysis is made for the casualties and economic damage caused by floods with a variety of return periods for the current situation and for the projected situation in the future. In the future, cultural and ecological vulnerability calculation are...
Conference Paper
Full-text available
Natural hazards do not only affect millions of people, but also cause material damages up to 300 billion USD per year worldwide. The SIDS (Small Island Developing States) are characterized by an extremely high vulnerability to these hazards, due to their low-lying, densely populated cities and their fragile economy. To limit the consequences of the...
Research
Full-text available
Surveys demonstrated that 3D visualisations have an enormous added value because they are more vivid and therefore more understandable and make it easier to imagine the consequences of a flood than 2D visualisations. In this research, the WebGIS will be created using Ol3-Cesium and open layers to visualise a flood event by dynamic layers in a 2D/3D...

Energy saving, reduction of greenhouse gasses and increased use of renewables are key policies to achieve the European 2020 targets. In particular, distributed renewable energy sources, integrated with spatial planning, require novel methods to optimise supply and demand. In contrast with large scale wind turbines, small and medium wind turbines (S...

Het project Windkracht 13 is gericht op het openbreken van de markt voor kleine en middelgrote windturbines (KMWT). Dit wordt gefundeerd door het uitvoeren van een JERTS-studie (Juridisch, Economisch, Ruimtelijk, Technisch, Sociaal) die de bestaande barrières duidelijk in kaart brengt en aan de hand hiervan ook aanbevelingen doet voor het verlagen...

In tegenstelling tot fotovoltaïsche systemen van gelijkaardige grootte, maken kleine en middelgrote windturbines in Vlaanderen nog geen deel uit van het vertrouwde energielandschap. Aan de hand van het demo-disseminatieproject Windkracht 13 wil de Universiteit Gent, in samenwerking met Tecnolec en met de steun van het Agentschap Ondernemen, de barr...

Project
A project for the quantification of economic, social, cultural and ecological damage as a consequence of floods. Different models are developed in raster-GIS, such as the LATIS-model used in Flanders, but also vector-GIS models used in other case studies in Flanders and overseas (SIDS, Jamaica, …). The objective is to realize a generic model applicable in different situations. http://www.geoweb.ugent.be/project-en/56b2fbc63004c06e6f468c30?r=cartogis http://www.geoweb.ugent.be/project-en/56b2fdce3004c06e6f468c34?r=cartogis http://www.geoweb.ugent.be/project-en/56b34f493004c06e6f468c68?r=cartogis http://www.geoweb.ugent.be/project-en/5858fe91c5d12c021ee4db80?r=cartogis
Project
The use of 3D models in the field of archaeology and cultural heritage is focussed on in this research. These 3D models are generated through highly accurate acquisition techniques such as photo modelling. To improve the quality of the models, platforms for aerial photography are deployed (e.g. unmanned aerial vehicles or helium balloons). After georeferencing, the 3D models can be applied for several purposes: monitoring archaeological sites, building a 3D cultural heritage inventory, disseminating information to the general public,... In this respect, the development of a 3D (or 4D) GIS with extensive query possibilities would provide various benefits. The determination of a suitable geometric model for the implementation in a 3D archaeological GIS is the central topic of this research. Applications in Mexico (site of Edzna, in collaboration with INAH-Campeche), in China (site of Yar City, in collaboration with Academia Turfanica and with Xinjiang Institute of Ecology and Geography, CAS), in Honduras, in Greece, …, and also in Belgium
Project
Previous studies have reported that Ghent (Belgium) and regions nearby are insufficiently protected against storm surge events from the North Sea, whether combined with high upper drainage by abundant rainfall or not. When a downpour occurs and drains can no longer effectively manage the amount of water, floods in and around the city of Ghent will cause damage to energy and transportation infrastructure and precipitate a disruption to the delivery of services. In this research, an analysis is made for the casualties and economic damage caused by floods due to a downpour that statistically takes place once every twenty, fifty, and hundred years (T20, T50, T100) for the current situation and for the projected situation in 2050. The impact of moderate to extreme floods in the territory of Ghent is investigated, wherein all fragile infrastructure and vulnerable functions are identified and described.
