Available in PDF, EPUB and Kindle. Book excerpt: Process-based morphodynamic modelling is one of the relatively new tools at the disposal of coastal scientists, engineers and managers. On paper, it offers the possibility to analyse morphological processes and to investigate the effects of various measures one might consider to alleviate some problems. For these to be applied in practice, a model should be relatively straightforward to set up. It should be accurate enough to represent the details of interest, it should run long enough and robustly to see the real effects happen, and the physical processes represented in such a way that the sediment generally goes in the right direction at the right rate. Next, practitioners must be able to judge if the patterns and outcomes of the model are realistic and finally, translate these colour pictures and vector plots to integrated parameters that are relevant to the client or end user. In a nutshell, this book provides an in-depth review of ways to model coastal processes, including many hands-on exercises.

This book was released on 2011-12-16 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this work qualitatively investigates the morphodynamic response of a large tidal inlet/basin system to future relative sea level rise (RSLR) using the state-of-the-art Delft3D numerical model. Understanding the potential impacts of RSLR on these systems is a prerequisite for their sustainable management due to their rich bio-diversity and the increase in economic activities and local communities in recent decades. The adopted approach used a highly schematised model domain analogous to the Ameland inlet in the Dutch Wadden Sea. Model simulations were undertaken applying tidal and wave boundary forcings with three IPCC projected RSLR scenarios (no RSLR, low RSLR and high RSLR). Predicted inlet evolution indicated a channel/shoal pattern typically observed at the Ameland inlet. RSLR enhances the existing flood-dominance of the system leading to erosion on the ebb-tidal delta and accretion in the basin. Under the no RSLR case, resulting bed evolution of the process-based model (Delft3D) tends to agree with empirical-equilibrium relations of the ASMITA model. Application of the low RSLR scenario resulted in quite stable tidal flat evolution. Model simulations with the high RSLR scenario indicated disappearing the tidal flats over time and turning the system into a lagoon. Applying nourishment hardly compensated the RSLR induced sediment demand of tidal flat evolution.

Available in PDF, EPUB and Kindle. Book excerpt: Shallow coastal environments, particularly sandy tidal basins, are com- ing under increasing pressures due to human development and a changing climate. This has led to a demand for long-term predictions of sediment transport using deterministic, process-based coastal area models. Due to continually growing model complexity this has involved an increased compu- tational cost, resulting in the development of a variety of methods to speed up computation time while having a minimal impact on model accuracy. The present body of work introduces one of the most popular speed-up methods, the Morphological Factor (MF) method, to the TELEMAC hydro-inforrnatics modelling system. Using the depth-averaged, shallow water hydrodynamic and sediment transport models, TELEMAC 2D and SISYPHE respectively, a long-term simu- lation of a schematised tidal basin system is conducted. From infinitesimal perturbations to an initially flat bed a highly regular morphological pattern is seen to evolve spontaneously through the processes of self-organisation, subsequently forming the basis of a dynamic and intricate tidal channel net- work. Due to the time-stepping nature of the model, the initial pattern is responsible for all future simulated morphologies, yet this linkage has re- ceived little attention in the literature. Further simulations identify the first stages of the bed pattern as a dissipative structure, requiring more energy from the flow to create and maintain than the initial flat bed itself, which is contradictory to a linear, mechanistic treatment of the system. Dunes, sedimentary bed forms ubiquitous to the coastal zone, have a sig- nificant impact on flow speed (and therefore sediment transport and morpho- logical change) through the roughness created by their geometry. Although the effects of dune-scale roughness on the flow and sediment transport are discussed in the literature the impact of a time-evolving roughness feedback between the bed and the flow in a coupled morphological model is poorly understood. In the present work a roughness feedback mechanism is imple- mented in TELEMAC 2D and SISYPHE and the predicted roughness is validated in a model of the Dyfi Estuary, Wales, using the results of a swathe sonar bathymetric survey. The model results show very promising agreement with the data given the simplifying assumptions made. The tidal residual sedi- ment transport rate in a simplified model case is shown to not only change in magnitude, but also in sign, between cases with and without bed roughness feedback, showing that the method has significant implications for long-term morphological change. Deterministic models are frequently used to predict changes in the long- term, yet their mechanistic nature forces the outcome to be sensitive to initial conditions. Natural systems, however, contain both deterministic and probabilistic elements that create structures and patterns at a variety of dif- ferent scales, many of which can be captured by process based models such as TELEMAC 2D and SISYPHE. In the present work a stochastic, infinitesi- mal perturbation is introduced to three otherwise identical long-term model simulations, resulting in system divergence through three independent mor- phological system parameters. The sensitivity to initial conditions and the important role of self-organisation are seen to produce dynamic morphologi- cal behaviour that is inherent to the theory of open, dissipative systems.

Download or read book Sediment Transport in Aquatic Environments written by Andrew Manning and published by BoD – Books on Demand. This book was released on 2011-10-03 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment Transport in Aquatic Environments is a book which covers a wide range of topics. The effective management of many aquatic environments, requires a detailed understanding of sediment dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Numerical models are often the tool used for predicting the transport and fate of sediment movement in these situations, as they can estimate the various spatial and temporal fluxes. However, the physical sedimentary processes can vary quite considerably depending upon whether the local sediments are fully cohesive, non-cohesive, or a mixture of both types. For this reason for more than half a century, scientists, engineers, hydrologists and mathematicians have all been continuing to conduct research into the many aspects which influence sediment transport. These issues range from processes such as erosion and deposition to how sediment process observations can be applied in sediment transport modeling frameworks. This book reports the findings from recent research in applied sediment transport which has been conducted in a wide range of aquatic environments. The research was carried out by researchers who specialize in the transport of sediments and related issues. I highly recommend this textbook to both scientists and engineers who deal with sediment transport issues.
