A priori determined model structures are common in catchment rainfall-runoff modeling. While this has resulted in many ready-to-use modeling tools, there are several shortcomings of a one-size-fits-all model structure. The uniqueness of catchments with respect to their hydrological behavior and the need to adapt model complexity to data...

Since the completion of the Eastern Scheldt project in 1987, in the south-western part of The Netherlands, there has been a decrease of tidal volume, range and current in the Eastern Scheldt estuary. This has led to morphologic changes in the basin. The channels are in demand of sediment and as the Eastern Scheldt barrier itself blocks most of...

It is impossible to imagine life without portable electronics like the laptop computer and cell phone. All these products are powered by a battery, granting them grid independence and all-round protability. Connectivity to the internet and an increase of functionality demands for a better battery. The d1irect methanol fuel cell (DMFC) system...

Construction technology utilizing prefabricated concrete elements is known as a ‘precast concrete system’. In Western countries, this system has been widely used in constructing bridges, office buildings and residential buildings. A precast concrete construction system provides the advantages of construction effectiveness, high levels of quality...

A huge amount of geographical datasets are becoming available in distributed environments like Spatial Data Infrastructures (SDI). These datasets are very heterogeneous since they come from different independent sources and surveys and are structured in different formats. In the context of a national SDI that needs to assure an adequate quality...

The main objective of the paper is to elaborate the possibilities of applying CityGML for cadastral purposes, drawing particular attention to the three-dimensional representation of buildings. Technical realization of the issue is executed at the conceptual level by integration the Land Administration Domain Model, officially published as an...

The level of complexity in consumer electronic products is one of the main concerns for Innovation and Development (I&D) departments in companies manufacturing and selling household appliances. Nowadays, consumer electronic products tend to have more and more functions resulting in complexity increase that makes it harder for users to understand...

Meijer, L.A. (author)
Deep-marine slope and base-of-slope hydrocarbon reservoirs are difficult to model and produce because of their size and complex nature. The oil and gas industry focuses on easily producible reservoirs in channelized deposits, thereby leaving considerable volumes in the more heterogeneous external levees and lobes. This thesis is on how such...

Scientific literature lacks a model which combines exposure to risk, risk, and the relationship between them. This paper presents a conceptual road safety framework comprising mutually interacting factors for exposure to risk resulting from travel behaviour (volumes, modal split, and distribution of traffic over time and space) and for risk ...

=Introduction= Worldwide there is an increasing amount of dredging activities, due to increasing demand for transport of goods over the world. These project are more and more near sensitive nature reserves and thereby a potential threat of biodiversity; which is a major concern for port developers, authorities, environmental organizations and...

Even without uncertainty about the model structure or parameters, the output of a hydrological model run still contains several sources of uncertainty. These are: measurement errors affecting the input, the transition from continuous time and space to discrete time and space, which causes loss of information about the input, discretization of...

Hydrological models frequently suffer from limited predictive power despite adequate calibration performances. This can indicate insufficient representations of the underlying processes. Thus, ways are sought to increase model consistency while satisfying the contrasting priorities of increased model complexity and limited equifinality. In this...

The development of a conceptual rainfall-runoff model generally requires calibration to obtain non-observable parameters. This becomes especially difficult in river basins where data are absent, frequently intermittent or inaccurate. Rainfall-runoff models are usually calibrated on discharge data that are derived from stage observations by means...

The district heating system is currently a natural monopoly. Introducing multiple producers on district heating networks could have many benefits. By developing a conceptual model that captures the technical, economic and institutional layers of the district heating system, a solid basis for a simulation model can be made. The proposed agent...

Hydrological models are used for several purposes, from reservoir management to stormflow prediction. However, their predictive power is often questionable. As most rainfall-runoff models are highly dependent on calibration, models often show deteriorated performance during the validation period. This is caused by too much focus on and trust in...
