The Model of Support for the Decision-Making Process, While Organizing Dredging Works in the Ports

open access: yesEnergies, 2021
The aim of the research was to create a decision-making model, which would be able to support planning, organizing and conducting the dredging works in the port area.

Influence of Trailing Suction Hopper Dredger Side-Casting Backfilling Parameters on Far-Field Plume Dispersion and Deposition of Sediments

open access: yesJournal of Marine Science and Engineering
Layered side-casting backfilling performed with a trailing suction hopper dredger (TSHD) is widely used in tidal waters, but its continuous moving release can generate a time-varying far-field sediment plume that complicates both backfilling control and ...

Numerical simulation of hydro-and morfodynamic effects of side channels design parameters [PDF]

open access: yes, 2012
Four side channel design parameters are analysed by two-dimensionally modelling the extremes with the numerical software package Delft3D. In order to advise how to minimise the maintenance activity dredging in rivers due to the construction of side ...

Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

open access: yesAdvanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.

Using a sand wave model for optimal monitoring of navigation depth [PDF]

open access: yes, 2005
In the Euro Channel to Rotterdam Harbor, sand waves reduce the navigable depth to an unacceptable level. To avoid the risk of grounding, the navigation depth is monitored and sand waves that reduce the navigation depth unacceptably are dredged. After the

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Numerical study on smoke temperature characteristics in T-shaped bifurcated tunnel fires

open access: yesJournal of Intelligent Construction
Due to the swift progress of subterranean urban transportation, various branching structures emerged one after another. When it brought significant convenience to people’s travel, the fire hazard associated with it could not be overlooked.
