Coastal engineering

Saltwater intrusion has become a significant problem in coastal regions across the globe, including Vietnam, impacting resident livelihoods, economies, and societies. Particularly, the Mekong Delta region plays a pivotal role in Vietnam’s economy and agriculture, serving as a crucial source for Vietnam’s socio-economic development and environmental sustainability.

With the impact of global climate change, saline intrusion into surface water in coastal areas has become a major issue. The water treatment using surface water in these areas has to deal with double issues including organic matters and salinity. This paper evaluated the trihalomethanes formation during the treatment of surface water at pilot scale using different disinfection dose and at different salinity levels.

Salinity intrusion poses significant challenges to coastal regions worldwide. Reliable salinity prediction models can provide valuable information to mitigate the impact and influence of salinity intrusion. However, their accuracy relies mainly on the selected input variables and used optimal models. This study employs the Bayesian Model Averaging (BMA) algorithm to evaluate input variable importance and select the most reliable salinity prediction model.

This study aims at exploiting and processing multi-temporal satellite images of the Google Earth Engine platform (GEE), combined with topographic data since 1965 to monitor changes in estuary and shoreline of the coastal area of Cua Dai, Tra Khuc river, Quang Nam province during a period of 1965–2021. The analysis results show shoreline changes and hot spots of erosion and landslides along the coast, on both sides of Cua Dai river.

The study determines the predominant hydrogeological controls on salinity distribution and salinization/freshening, proposing conceptual models to explain the different vertical distributions of groundwater salinity at the coastline. An improved understanding of the sources of salinity and the hydrogeological controls will subsequently provide support for the future management of groundwater in the Western Port Basin, and serve as a template for how to unravel complex salinity distributions in coastal aquifers, and their relationships to palaeo- and recent geomorphological histories.

The sustainability and prosperity of the ancient civilizations of China, Egypt, Babylonia, Phoenicia, Persia and Roma were based on the extensive use of water for human consumption, crop irrigation, canal navigation and energy generation. Today, the worldwide scarcity of water and clean energy constitutes a central and critical problem for the whole humankind. This situation is aggravated as industrial, agricultural and municipal effl uents reach the water bodies, or the coastal seawater that is used as feed for desalination plants.

Words can easily borrow, but the meaning of love from the heart of a people is difficult to describe. So I want to ask for forgiveness from the people that support can not be appreciated in the words and from those who, by any chance, I forgot to mention. First of all what I want to thank prof. dr.ir. Wind Herman and his wife - Joke. The interviews with prof. Wind held in Bangkok and his decision has helped me to be here, at the University of Twente, to carry out my doctoral research. Herman and Joke, I will never forget...

Average depth model has a variety of applications in hydraulic engineering, especially in applications that flow depth is much smaller than the width of the flow. In this method the vertical variation is negligible and the hydraulic variables average integrated from channel bed to the surface free for the vertical axis. in equations arising management, pure hydrostatic pressure is assumed that not really valid in the case of flow in the bed is curved and can not be described curvature effects of the bed.

Embankment crest and the toe: that is limited to the scope of protection of the embankment on the shore. Roof slope: expressed as the ratio, for example 1:3. Roof more comfortable (less steep), the embankment as a protective effect, but the price will be more expensive (for large embankment surface). Structure and size of the overlay: Overlay roof design must be capable of against the effects of currents, waves, etc. Conventional coatings include removable components assembled together.

Coast (littoral or coastal) is defined as where land and sea borders. [1] The exact boundary is called the coastline, but this factor is difficult to determine due to the influenceof the tide. The term "coastal zone" is also used to replace the coast because it refers to an area of ​​occurrence of the interaction between sea and land. [2] Both terms can be used to refer to the geographic location or region; example, the west coast of New Zealand, or the East Coast and West coast of the United States....
