Aranguren Rojas, Ignacio (author)
This thesis adopt existing methodologies for flood-risk assessment in other civil infrastructure (such as dams or urban flooding) and apply them in road type infrastructure in order to quantitatively assess flood vulnerability and risk in project locations where historical closure data is not available and the complex global network-approach...

For an accurate prediction of the porosity of a liquid-solid homogenous fluidized bed, various empirical prediction models have been developed. Symbolic regression machine learning techniques are suitable for analyzing experimental fluidization data to produce empirical expressions for porosity as a function not only of fluid velocity and...

One of the most popular and frequently used models for describing homogeneous liquid-solid fluidised suspensions is the model developed by Richardson & Zaki in 1954. The superficial fluid velocity and terminal settling velocity together with an index makes it possible to determine the fluid porosity in a straightforward way. The reference...

This research article presents a model-based framework for detecting and localizing leaks in water distribution networks (WDNs). The framework uses optimization and systematic search space reduction. The method employs two stages: (1) the search space reduction (SSR) stage and (2) the leakage detection and localization stage (LDL). During SSR...

To make informed flood risk management (FRM) decisions in large protected river systems, flood risk and hazard analyses should include the potential for dike breaching. 'Load interdependency' analyses attempt to include the system-wide effects of dike breaching while accounting for the uncertainty of both river loads and dike fragility. The...

In this study a simplified model of the rivers Tigris and Euphrates during the Uruk period (3500-3100 B.C.) was created in order to define the hydraulic behaviour of the rivers in ancient Mesopotamia. The model was used to test the effect of a number of factors on the water-level of the river system. Especially, the role of the development of...

In physical model tests there is often a need of preventing stones from moving. This can be achieved by gluing the stones. Applying PBA (Polyurethane Bonded Agregate, e.g. Elastocoast) guarantees no moving stones, a normal permeability and a transportable model.

The present thesis aims to improve the current description of the SPM by deriving optimal values for the model’s input parameters. With the use of suitable optimization algorithms, the objective is to capture the spatial variability of the key model parameters.

The technique of active microwave remote sensing has made much progress toward its high potential to monitor water storage changes in terrestrial surface and subsurface water bodies at various spatial and temporal scales. The number of studies demonstrating the support these data can offer in hydrological and hydraulic model building, model...

Understanding the interactions between the ecosystem and the morphology of river floodplains, i.e. floodplain biogeomorphology, is becoming increasingly important in view of modern river management and climate change. There is a need for predictive models for the natural response of river floodplains to hydraulic measures and river...

The main objective of this research is the determination of the effect of spatial resolution on hydrological model performance. In order to do so, a model of the Meuse basin was setup at the appropriate scales of Booij (2001) in the existing HBV structure and compared with a model of lower resolution (HBV-15). This comparison was made in three...

Sharks require a certain current condition in their basin for survival. The shark basin of Blijdorp zoo (Rotterdam) has been modeled in order to provide information regarding the currents in the basin and to optimize the physical environment for the sharks in the basin

Manual for the program DUFLOW, a micro-computer package for the simulation of one-dimensional unsteady flow and water quality in open channel systems. Duflow is a one-dimensional network programme. The model can be used for irrigation and drainage networks, for tidal flow in estuaries, and may include water quality parameters.

In Chapter 2 of this report an overview is given on fluvial processes involved in the modelling discussed. Chapter 3 is concerned with scale models, whilst Chapter 4 deals with numerical models. The main problems treated are, firstly, modelling of the water movement, followed by sediment transport and morphology. Attention is also given to the...

Hydraulic scale models and numerical models, both overall as well as detailmodels, were constructed for the Eastern Scheidt estuary and also for the storm-surge barrier and surroundings (during various stages of construction). Most types of investigations were performed in more than one model. On the other hand several extensive field campaigns...
