Book excerpt: Abstract: With the Maumee River/Lake Erie confluence requiring continuous dredging of two permanent bed mounds to remain a viable harbor, the goal of this dissertation is to research the hydrodynamic patterns and sediment transport characteristics under different forcing conditions in the confluence, with the objective of seeking the origin and physics of the two mobile sediment humps in the navigation channel of the river. As an outcome, this dissertation should help provide guidance as to why, when, and how dredging should be done in the region. An integrated three dimensional, hydrodynamic, sediment transport, wave current bottom boundary layer, and wave model is applied to simulate the hydrodynamics and sediment transport. A curvilinear planform grid with 208 by 79 cells in the horizontal direction and 12 sigma layers in the vertical direction is used to cover the whole lake and the 11 km long dredged channel of the Maumee River. After analysis of the existing Lake Erie literature, 18 hydrodynamic and 14 sediment transport application cases are constructed, based on different combinations of the forcing functions on the lake and river. In addition to generating the Lake Erie circulation patterns often described in published literature by other researchers, the hydrodynamic modeling conducted in this dissertation also has obtained new insight on confluence physics. The analysis of the sediment simulation results shows that the hump closer to the Maumee Bay (hump 2) is mainly deposited and sustained by the river bottom sediment resuspension. The upstream hump (hump 1) is mainly deposited and maintained by the riverine sediment deposition. Under steady SW winds, the deposition at hump 1 is the strongest in spring, less so in summer, and weakest in fall; the deposition at hump 2 is in the reversed order. Under steady NE winds, the deposition at hump 1 is the strongest in fall, less so in summer, and weakest in spring; the deposition at hump 2 is in the reversed order.

Available in PDF, EPUB and Kindle. Book excerpt: Following years of research, the first bored tunnel in soft soil in the Netherlands, the Tweede Heinenoord tunnel, was completed in 1998. Since then, Dutch engineers have increased their knowledge of soft soil tunnelling, with a significant and important part of this research being carried out by GeoDelft, the Dutch National Institute of Geo-Engineering. This book contains the most important publications by GeoDelft on the subject of soft soil tunnelling, focusing on the period from 1992 to the present, it is divided into four main headings: field measurements; grout behaviour; model testing; and numerical analysis. This impressive overview of the progress made in the Netherlands in soft soil tunnelling research over more than a decade is a valuable resource to those working in soft soil tunnelling worldwide.

Book Synopsis Modeling of Hydrodynamics and Sediment Transport in the Mekong Delta by : Vo Quoc Thanh
Download or read book Modeling of Hydrodynamics and Sediment Transport in the Mekong Delta written by Vo Quoc Thanh and published by CRC Press. This book was released on 2021-06-01 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research aims to investigate the prevailing sediment dynamics and the sediment budget in the Mekong Delta by using a process-based model. Understanding sediment dynamics for the Mekong Delta requires high resolution analysis and detailed data, which is a challenge for managers and scientists. This study introduces such an approach and focuses on modeling the entire system with a process-based approach with Delft3D-4 and Delft3D Flexible Mesh (DFM). The first model is used to explore sediment dynamics at the coastal zone. The latter model allows straightforward coupling of 1D and 2D grids, making it suitable for analyzing the complex river and canal network of the Mekong Delta. The validated model suggests that the Mekong Delta receives ~99 Mt/year sediment from the Mekong River. This is much lower than the common estimate of 160 Mt/year. Only about 23% of the modelled total sediment load at Kratie is exported to the sea. The remaining portion is trapped in the rivers and floodplains of the Mekong Delta. The results advance understanding of sediment dynamics and sediment budget in the Mekong Delta. As such the model is an efficient tool to support delta management and planning.

Book Synopsis Modeling and Practice of Erosion and Sediment Transport under Change by : Mohamed Meddi
Download or read book Modeling and Practice of Erosion and Sediment Transport under Change written by Mohamed Meddi and published by MDPI. This book was released on 2019-09-17 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.

Book Synopsis Hydrodynamics, Sediment Transport and Morphodynamics at Inlets and River Mouths by : Jia-Lin Chen
Download or read book Hydrodynamics, Sediment Transport and Morphodynamics at Inlets and River Mouths written by Jia-Lin Chen and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inlets and river mouths are among the most important coastal zones in terms of their economic, ecological and societal values. However, our current predictive capability on the hydrodynamics, sediment delivery and morphological evolution of inlets and river mouths remains qualitative. The overarching goal of this study is to enhance the physical understanding and model development of inlet/river mouth dynamics. The newly developed nearshore circulation model, SHORECIRC, using a hybrid finite-difference finite-volume TVD-type scheme, is coupled with the wave model SWAN and several sediment transport model. This new nearshore modeling system is called NearCoM-TVD. The capability and limitation of NearCoM-TVD for several coastal applications, including tidal inlet hydrodynamics, nearshore wave-current interaction and sandbar migration are evaluated.
