Application of an Innovative Jet Pump System for the Sediment Management in a Port Channel: Techno-Economic Assessment based on Experimental Measurements

Journal of Marine Science and Engineering, 2020
The realization of infrastructures in coastal environment modifies water and sediment natural current regime. In particular, sediment can be entrained and accumulated in port infrastructure like docks, haling basins, or port entrances and channels ...

Climate‐driven intraspecific shifts in seed germination phenology: Consequences for native temperate woodland restoration and regeneration

PLANTS, PEOPLE, PLANET, EarlyView.
As climate change alters seasonal patterns, temperate tree populations face a growing risk of phenological mismatch, where seed dispersal and germination no longer align with favourable conditions for survival. This study predicted how warming by the end of the century will affect seed dormancy breaking and germination in populations of three UK tree ...

Valorization of saline dredged sludge by low-carbon geopolymer production: Salt content impact, mechanisms, and carbon emissions

Results in Engineering
This study demonstrates a green and low-carbon approach for valorizing saline dredged sludge (DS) by producing geopolymers from DS combined with fly ash (FA) and ground granulated blast furnace slag (GGBS), activated by an alkaline activator ...

Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream

River Research and Applications, EarlyView.
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...

Can Environmental Markets Pay for More Sustainable Farm Dams? A Cost–Benefit Analysis

Sustainable Development, EarlyView.
ABSTRACT Farm dams are widespread artificial waterbodies that play a critical role in agricultural water security. Enhancing these systems through sustainable interventions such as fencing, hardened access points, and revegetation can improve water quality and deliver carbon and biodiversity co‐benefits.

Impact of operational parameters on turbidity generation in cutter suction dredging: Insights from a numerical model and sensitivity analysis

Applied Ocean Research
The cutter suction dredger (CSD) is one of the main vessels utilized in the dredging industry. The dynamic actions related to its rotating cutter head are the main trigger for sediment release and turbidity generation by this vessel.

Tourism as a Catalyst for Blue Carbon Restoration and Conservation: Pathways, Gaps, and Opportunities

Sustainable Development, EarlyView.
ABSTRACT Tourism is a major driver of coastal economies worldwide, yet it is also a growing source of pressure on blue carbon ecosystems (BCEs) such as mangroves, seagrasses, and salt marshes. Nowadays, tourism‐led conservation/restoration is increasingly promoted under the banner of regenerative tourism, but how these projects are motivated ...
