Influence of hydraulic resistance on flow features in an open channel confluence [PDF]

, 2014
A numerical model based on the 3D shallow water equations is set up for a 90° angle open channel confluence. The model is first calibrated and validated using experimental data by (Shumate, 1998).

Modeling daily soil salinity dynamics in response to agricultural and environmental changes in coastal Bangladesh [PDF]

, 2017
Understanding the dynamics of salt movement in the soil is a prerequisite for devising appropriate management strategies for land productivity of coastal regions, especially low-lying delta regions, which support many millions of farmers around the world.

Addressing Unwanted Morphodynamic Processes in Re‐Naturalization Projects

River Research and Applications, Volume 42, Issue 2, Page 507-522, February 2026.
ABSTRACT River systems worldwide are undergoing severe ecological and morphological degradation due to prolonged anthropogenic interventions, such as channelization and dam construction, which disrupt sediment continuity and natural flow regimes. In response, river re‐naturalization projects have emerged as essential strategies to restore the dynamics ...

Kajian Sedimentasi di Muara Sungai Ciletuh, Kabupaten Sukabumi

Jurnal Teknik Sipil, 2020
Fishermen around Ciletuh estuary were having difficult times due to their lack of fish cathments. This happens because of sedimentation on Ciletuh estuary, causing the fishermen unable to moor their boats.

Mesh, Hydrodynamic Boundary, and Uncertainty Analysis of the 2D‐SWEs: Taking Numerical Simulation of River Networks as an Example

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Targeting the issues of insufficient predictive ability and inefficient computation in two‐dimensional shallow water equations (2D‐SWEs), this study deeply couples the mesh and hydrodynamic boundary, constructing multiple 2D hydrodynamic models (run 2,640 times).

Subsurface sediment properties and potential impacts of marine sand extraction on sand wave occurrence on the Netherlands Continental Shelf

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
This study reveals that a deeper sediment layer on the Netherlands Continental Shelf, which is exposed due to sand extraction, is generally finer and muddier than the previous surface layer. Additionally, the exposure of this layer will generally lead to a reduced occurrence of sand waves.

Numerical study on the influence of salt marsh plants on coastal wetland hydrodynamics and suspended sediment transport

Frontiers in Environmental Science, 2023
Salt-marsh plants play important roles in the hydrodynamics and sediment transport and deposition processes in coastal regions. The Delft3D model was applied to quantify the influence of salt-marsh plants on the hydrodynamic characteristics and suspended

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

, 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 ...

Wave and Tidal Controls on Embayment Circulation and Headland Bypassing for an Exposed, Macrotidal Site [PDF]

, 2018
Headland bypassing is the transport of sediment around rocky headlands by wave and tidal action, associated with high-energy conditions and embayment circulation (e.g., mega-rips).

Morphodynamic Modeling of a Flood Event at a Restored Alpine River Reach

River Research and Applications, Volume 41, Issue 10, Page 2136-2156, December 2025.
ABSTRACT Morphodynamic models are essential tools for estimating sediment dynamics along river reaches. A wide range of bedload transport equations is available, and applying these models to river restoration projects and river widenings requires simplifying assumptions about slope effects, secondary currents, and bank failure, introducing significant ...
