The Effect of an Underwater Sill against Salt Intrusion on Port Logistics

This research study has investigated the effects of sills as a nature-based countermeasure to reduce saltwater intrusion within Rijnmond Drechtsteden. The effects of this measure have been assessed regarding its impact on port logistics and freshwater supply in the region. The heavily dredged New Waterway provides the vital open connection to...

Hydrogeological Modelling of the Esperance Drinking Water Aquifer Subjected to Seawater Intrusion

Saltwater intrusion in groundwater is a concern in many aquifers around the world. It results in deterioration of potable and irrigation water quality and degradation of ecosystems. The problem is exacerbated by fresh groundwater abstraction, drying climates and a rising seawater level.<br/>Esperance is a small town situated on the south coast...

A systematic tool for the assessment of nature-based solutions to mitigate salt intrusion

Nature-based initiatives have emerged as potential solutions to problems caused by saltwater intrusion in deltas found globally, but their successful implementation is enabled partly by a multi-stakeholder approach. The latter involves managing several parallel stakeholder objectives, which usually requires quantitative knowledge to understand...

Combining Water Resources, Socioenvironmental, and Psychological Factors in Assessing Willingness to Conserve Groundwater in the Vietnamese Mekong Delta

Freshwater resources in coastal areas are under intense pressure from excessive groundwater extraction, which amplifies saltwater intrusion (SWI) into coastal freshwater aquifers, such as in the Mekong Delta. Studies that combine socioenvironmental data and households' psychological factors next to salinity measurement data to design...

Seawater Intrusion Modeling with Single Density Codes

Seawater intrusion modeling is challenging either because of a lack of many approaches' ability to cope with complex environments or significant computational expense. Seawater intrusion models also face issues with parameterization and validation due to problems with many parameters and also a lack of observational data. Bakker and Schaars ...

Dynamic Response of the Fluid Mud to a Tropical Storm

Fluid mud (FM) is a unique sedimentary feature in high-turbidity estuaries, where it can make a rapid contribution to morphodynamics. Insufficient field measurements and fixed-point monitoring lead to deficient understandings of the formation, transport, and breakdown of the FM under extreme weather conditions. A field survey was conducted in...

The role of behavioural willingness on mitigating saltwater intrusion in the Vietnamese Mekong Delta: Combining socioeconomic data with groundwater simulations using Bayesian Belief Networks

Fresh water resources in coastal areas are under intense pressure from groundwater consuming activities, sea level rise and extreme weather events, which effectively amplify salt water intrusion (SWI) into coastal freshwater aquifers. Literature on SWI describe the effects of SWI, model SWI scenarios and explain possible SWI mitigation...

Impacts of sea level rise and groundwater extraction scenarios on fresh groundwater resources in the Nile Delta Governorates, Egypt

As Egypt's population increases, the demand for fresh groundwater extraction will intensify. Consequently, the groundwater quality will deteriorate, including an increase in salinization. On the other hand, salinization caused by saltwater intrusion in the coastal Nile Delta Aquifer (NDA) is also threatening the groundwater resources. The aim...

Impact of Sea Level Rise on Agriculture Using Groundwater in Bangladesh

Bangladesh, located on the northern littoral of the Bay of Bengal, is one of the most vulnerable countries to the impacts of climate change and sea level rise. Agriculture is the prime economic activity in the densely populated coastal areas of the country. During the dry season of the year (November to April), when rainfall is low, the...
