As one of the most important freight transportation modes, maritime transport has been the backbone of international trade and global economy. From the cargo flow point of view, seaports and inland shipping link the individual countries and the global waterborne transportation networks. To analyze the current ship traffic and port performance or...

Climate change is incompatible with the assumption of stationarity. This has lead to a sharp increase in the detection and study of nonstationarity in hydro-meteorological processes. Most hydro-meteorological processes are still analyzed by studying time series of observations. From the perspective of statistical characteristics, a stationary...

Applying deep neural networks (DNNs) for system identification (SYSID) has attracted more andmore attention in recent years. The DNNs, which have universal approximation capabilities for any measurable function, have been successfully implemented in SYSID tasks with typical network structures, e.g., feed-forward neural networks and recurrent...

Estuaries are partially enclosed water bodies where river water mixes with sea water. Estuaries provide important ecological functions which are strongly regulated by estuarine hydrodynamics and sediment dynamics, and also by human interventions. Sustainable management of such systems therefore requires a thorough understanding of the interplay...

Ground-penetrating radar (GPR), usually working in the frequency from tens of megahertz to several gigahertz, is widely applied in mapping near-surface applications. In recent decades, GPR is frequently utilized for fluid-related applications, such as groundwater assessment, contaminant monitoring, and water-filled fracture detection, based on...

Stability of dikes is a national security issue for densely populated low-lying countries situated in delta areas, like the Netherlands. One of the dominant dike failuremechanisms in the Netherlands is piping, where high seepage flow rates transport sand particles and subsequently form a ’pipe’ under a dike structure. As such, one manner to...

3D city models are increasingly used to maintain and improve urban infrastructure. Keeping 3D city models accurate and up-to-date is essential for municipalities to make decisions in a time of strongly increasing urbanization. 3D information provided by airborne laser scanning (ALS) is widely used for generating 3D city models. However, ALS data...

Pipe failures in water distribution systems can have a serious impact and hence it’s important to maintain the condition and integrity of the distribution system. This book presents a whole-life cost optimisation model for the rehabilitation of water distribution systems. It combines a pipe breakage number prediction model with a pipe...

Reinforcement Learning (RL) methods are relatively new in the field of aerospace guidance, navigation, and control. This dissertation aims to exploit RL methods to improve the autonomy and online learning of aerospace systems with respect to the a priori unknown system and environment, dynamical uncertainties, and partial observability. In the...

The research presented in this thesis focuses on the use of hydrate slurries in the air conditioning and refrigeration areas. Both experimental and mathematical methods have been used. Hydrate slurries have been suggested as promising cold storage materials that can be used in air conditioning systems due to their high latent heat (193 kJ/kg and...

What are the principles that make societal problems socio-technically complex? And, even more important, how can we support public policymaking in the wake of socio-technical complexity? In The Princess in the Castle, the author investigates if, why and how serious games and game-like simulations (SGs) can support integrated policy making and...

Building new towns seems to be a rational approach that releases pressure from overly burdened large cities. This strategy was developed in Western Europe in the middle of twentieth century. Since the 1990s, the European new town model has been widely implemented in China. However, the author questions the feasibility of the large-scale, hasty...
