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 excerpt: The Central Mekong Delta Region Connectivity Project aims to enhance connectivity across provinces of southern Viet Nam and Ho Chi Minh City. It includes two major bridges, a 15-kilometer road connecting the two bridges, and approach roads. Given the high exposure of the Mekong Delta to severe flooding, a climate risk and vulnerability assessment was conducted to assess the vulnerability of the project to climate change. The assessment report provides a better understanding of climate change threats to the project infrastructure. It also provides project stakeholders with information necessary for consensus building for the adoption of a robust approach to responding to climate change. The study illustrates that a constrained time frame and limited resources may not be significant impediments to the undertaking of climate risk vulnerability assessments, which can provide valuable information at the project design stage to increase the climate resilience of large investment projects.

Book excerpt: The Mekong River Basin: Ecohydrological Complexity from Catchment to Coast, Volume Three presents real facts, data and predictions for quantifying human-induced changes throughout the Mekong watershed, including its estuaries and coasts, and proposes solutions to decrease or mitigate the negative effect and enable sustainable development. This is the first work to link socio–ecological interaction study over the whole Mekong River basin through the lens of ecohydrology. Each chapter is written by a leading expert, with coverage on climate change, groundwater, land use, flooding drought, biodiversity and anthropological issues. Human activities are enormous in the whole watershed and are still increasing throughout the catchment, with severe negative impacts on natural resources are emerging. Among these activities, hydropower dams, especially a series of 11 dams in China, are the most critical as they generate massive changes throughout the system, including in the delta and to the livelihoods of millions of people and they threaten sustainability. Presents an extensive collection of eco-hydrological changes in the river basin driven by both nature and anthropological factors Provides state of the art modeling, data analysis methodologies for complex socio-ecological complexity applied in the Mekong river basin Includes specific cases of ecohydrology in the river basin, especially from the Mekong delta

Available in PDF, EPUB and Kindle. 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.

This book was released on 2020-04-22 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many estuaries are located in urbanized, highly engineered environments. Cohesive sediment plays an important role due to its link with estuarine health and ecology. An important ecological parameter is the suspended sediment concentration (SSC) translated into turbidity levels and sediment budget. This study contributes to investigate and forecast turbidity levels and sediment budget variability at San Francisco Bay-Delta system at a variety of spatial and temporal scales applying a flexible mesh process-based model (Delft3D FM). It is possible to have a robust sediment model, which reproduces 90% of the yearly data derived sediment budget, with simple model settings, like applying one mud fraction and a simple bottom sediment distribution. This finding opens the horizon for modeling less monitored estuaries. Comparing two case studies, i.e. the Sacramento-San Joaquin Delta and Alviso Slough, a classification for estuaries regarding the main sediment dynamic forcing is proposed: event-driven estuary (Delta) and tide-driven estuary (Alviso Slough). In the event-driven estuaries, the rivers are the main sediment source and the tides have minor impact in the net sediment transport. In the tide-driven estuaries, the main sediment source is the bottom sediment and the tide asymmetry defines the net sediment transport. This research also makes advances in connecting different scientific fields and developing a managerial tool to support decision making. It provides the basis to a chain of models, which goes from the hydrodynamics, to suspended sediment, to phytoplankton, to fish, clams and marshes.

Available in PDF, EPUB and Kindle. Book excerpt: The interface of 440,000 km long coastline in the world is subject to global change, with an increasing human pressure (land use, buildings, sand mining, dredging) and increasing population. Improving our knowledge on involved mechanisms and sediment transport processes, monitoring the evolution of sedimentary stocks and anticipating changes in littoral and coastal zones is essential for this purpose. The special issue of Water on “Sediment transport in coastal waters” gathers thirteen papers which introduce the current revolution in the scientific research related to coastal and littoral hydrosedimentary dynamics, and reflect the diversity of concerns on which research in coastal sediment transport is based, and current trends — topics and preferred methods — to address them.
