EuroSDR (http://www.eurosdr.net/) is a non-profit organisation that provides a pan-European network that brings together mapping / cadastre agencies and academia for the purpose of applied research, and securing timely, research-based knowledge that allows the agencies to play their role as content providers and government competence centres...

Piping failure of levees is one of the main contributors to flood risk. Piping occurs when the head difference over a levee results in uplift of the inland blanket, followed by backward erosion in the aquifer due to high local flow velocities. Whether piping occurs, highly depends on local geo-hydrological circumstances which are uncertain due...

In many geotechnical projects, field data is used to determine the soil parameters. In most instances, however, the statistical analysis is performed ad hoc and the spatial distribution of this data is not (expclitly) accounted for. A more formal statistical approach allows to make better use of the data and combine it in a consistent manner...

This contribution presents an innovative and integrated framework for real-time-process reconciliation and optimization (RTRO) in large continuous open pit coal mines. RTRO-Coal is currently developed, validated, tested and implemented as part of a multi-national multi-partner European Union funded R&D project. The key concept is to promote a...

Decision Support Systems (DSSs) that are used nowadays by water managers often predict states that do not correspond with the observed states. This is caused by changing parameters in the real systems, while the parameters used in the current DSSs are kept at a fixed level or follow a temporal pattern that does not always represents reality....

Dikes and levees play a crucial role in flood protection in deltaic areas such as the Netherlands. Internal erosion piping or under-seepage is a major cause of levee failures and a main contributor to the probability of failure of river levees due to the large (mostly geotechnical) uncertainties. The present thesis investigates how geotechnical...

There are many applications that use maps, and more detailed the maps are, more applications can benefit from the map. Many maps are still manually created and also the underlying attributes are informed in a manual process. This thesis presents a method to automatically derive and update attribute road data by mining and analyzing movement...

Modern and future aerospace structures make increasing use of fiber reinforced composite materials to optimize structural performance. Yet, characterizing the composite material properties is very expensive and time consuming. Parameters like non-linear shear and their interactions with stresses perpendicular to the fiber direction are hardly...

Piping is one of the main failure mechanisms for flood defences. This paper gives an overview of recent developments in the reliability analysis for this mechanism in the Netherlands. These comprise new approaches in the treatment of heterogeneity of the subsoil with respect to the failure process, the inclusion of information from field...

The potential for volunteer groups to contribute geographic data to National Mapping Agencies has been widely recognised. Several investigations have been done to determine the geometric accuracy of this data for the purposes of national mapping. Beyond accuracy, from a production perspective National Mapping Agencies will also be interested in...

This thesis describes the implementation of available bandwidth link-state update policies for Quality of Service routing. Periodic, threshold-based and class-based policies are described and implemented in a QoS router testbed, using Quagga and its OSPF-API for low-level communications. The implementation is thoroughly tested using unit tests...

Schweckendiek, T. (author)
The reliability of flood defenses is often dictated by large uncertainties in the hydraulic loading and the structural resistance. Additional information decreases uncertainty, however, acquiring it is often costly. One source of information, even though in many cases readily available, is hardly used – survived loads. This article shows how...

Monitoring of tree objects is relevant in many current policy issues and relate to the quality of the public space, municipal urban green management, management fees for green areas or Kyoto protocol reporting and all have one thing in common: the need for an up to date tree database. This study, part of the Tree and Image research project,...

Piping, also called under-seepage, is an internal erosion mechanism, which can cause the failure of dikes or other flood defence structures. The uncertainty in the resistance of a flood defence against piping is usually large, causing high probabilities of failure for this mechanism. A considerable part of this uncertainty is of epistemic nature...

Automated approaches to building detection in multi-source aerial data are important in many applications, including map updating, city modeling, urban growth analysis and monitoring of informal settlements. This paper presents a comparative analysis of different methods for automated building detection in aerial images and laser data at...

Change detection with very high resolution imagery is difficult, because 3D objects as buildings appear differently in 2D imagery due to varying viewing angles and sun positions. This research proposes a method to improve change detection by using simple 3D models of buildings. Buildings have been modelled as flat roof or gable roof buildings....

In this paper we present a generic primal-dual interior point methods (IPMs) for linear optimization in which the search direction depends on a univariate kernel function which is also used as proximity measure in the analysis of the algorithm. The proposed kernel function does not satisfy all the conditions proposed in
