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.

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.

River Flow 2024 features keynote lectures and contributed papers presented at the 12th International Conference on Fluvial Hydraulics, held from September 2nd to 6th, 2024, in Liverpool. River Flow 2024 provides an overview of the latest experimental, theoretical, and computational findings on fundamental river flow and transport processes, river morphology, and morphodynamics. It also addresses the impacts of hydraulic structures on flow regimes, river morphology, and ecology; sustainable river engineering practices, including stream restoration and re-naturalization; and the effects of climate change, including extreme flood events. Additionally, the conference covers topics such as sediment, pollutant, and microplastic dynamics in rivers; fluid mechanics, numerical modelling, and two-phase flow; monitoring techniques and artificial intelligence; and natural flood management, vegetation, wood, and river restoration. River Flow 2024 aims to present ongoing and the state-of-the-art in river research and engineering, targeting academics and practitioners in hydraulics, hydrology, and environmental engineering. Organized under the auspices of the Committee on Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR), the River Flow conference series has gained international recognition as one of the most reputable events in the fluvial hydraulics community, attracting a large and loyal audience of river researchers and engineers. Thanks to the Stephen E. Coleman Award for the best research paper from a young academic and for its mission focused towards promoting knowledge transfer and idea exchange, it has also become a point of reference for the early career researcher and younger academics, with the master classes at the centre of it. The 12th edition also featured the “Networking and Mentoring Event: Embracing Gender Equity and Diversity” to enable all the member of the community to maximise their opportunity withing the sector.

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.

Rivers in the Landscape: Science and Management offers a comprehensive and accessible overview of the current state of knowledge for river process and form, taking a holistic approach to the subject with coverage of integrated river science and management in practice. The processes and forms present in channelized surface flow–rivers–are systematically explored in this book to • emphasize the connectivity between rivers and the greater landscape by explicitly considering the interactions between rivers and tectonics, climate, biota, and human activities; • provide a concise summary of the current state of knowledge for physical process and form in rivers; • reflect the diversity of river environments, from mountainous, headwater channels to large, lowland, floodplain rivers and from the arctic to the tropics; • reflect the diverse methods that scientists use to characterize and understand river process and form, including remote sensing, field measurements, physical experiments, and numerical simulations; • reflect the increasing emphasis on quantification in fluvial geomorphology and the study of Earth surfaces in general; • provide both an introduction to the classic, foundational papers on each topic, and a guide to the latest, particularly insightful and integrative references. Aimed at advanced undergraduate students, graduate students, and professionals looking for a concise summary of physical aspects of rivers, this book emphasizes general principles and conceptual models, as well as concrete examples of each topic drawn from the extensive literature on river process and form.
