Salt marshes are important ecosystems but their resilience to sea-level rise and possible increases in storm intensity is largely uncertain. The current paradigm that a positive sediment budget supports the survival accretion of salt while deprivation causes marsh degradation. However, few studies have investigated combined impact increased on marsh. This study investigates under various surge ...

Salt marshes can contribute to coastal protection, but the magnitude of protection depends on width marsh. The cross-shore marsh is a large extent determined by delicate balance between seaward expansion and landward retreat. influence daily occurring mild weather conditions sediment availability variability salt has not been systematically assessed. This paper investigates how homogeneous hydr...

Numerical morphological modelling of braided rivers is increasingly used to explore controls on river pattern and for applied environmental management. This article reviews and presents a taxonomy of braided river morphodynamic models and discusses the challenges facing model development and use, illustrating these challenges with a case example. The taxonomy is contextualised by an initial dis...

More than 18 million seabirds nest on 58 Pacific islands protected within vast U.S. Marine National Monuments (1.9 million km2). However, most of these seabird colonies are on low-elevation islands and sea-level rise (SLR) and accompanying high-water perturbations are predicted to escalate with climate change. To understand how SLR may impact protected islands and insular biodiversity, we model...

Intertidal shoals are pronounced morphological features found in many estuaries worldwide. Apart from maintaining an ecologically unique intertidal environment, also protect adjacent dyke systems by attenuating waves. The fate of sandy under anticipated sea level rise (SLR) scenarios is underexplored. current research investigates the long-term morphodynamic evolution estuarine forcing short fe...

A calibrated three-dimensional numerical model (Delft3D) and in-situ observations are used to study the relation between deep-water temperature deep mixing in Lake Garda (Italy). model-observation comparison indicates that is able adequately capture turbulent kinetic energy production surface layer its vertical propagation during unstratified conditions. From modeling results several processes ...

Microplastics pollution has led to irreversible environmental consequences and triggered global concerns. It been shown that water resources marine food consumers are adversely affected by microplastics due their physico-chemical characteristics. This study attempts comprehensively review the structure of four well-known Lagrangian particle-tracking models, i.e., Delft3D—Water Quality Particle ...

Estuaries are areas that vulnerable to the impacts of climate change. Understanding how these affect complex environments and their uses is essential. This paper presents a work based on an analytical solution 2DH 3D versions Delft3D numerical model simulate Minho River estuary its saline wedge length under change projections. Temperature observations at several locations in region were selecte...

A complete annual cycle of the dynamics fine-grained sediment supplied by Omo and smaller rivers is simulated for Lake Turkana, one world’s large lakes, with hydrodynamic, wave transport model Delft3D. The forced river liquid solid discharge wind data in order to simulate cohesive resuspension. It simulates stratification due salinity, generation dissipation, advection resuspension waves curren...

Because its location is quite close to the Vietnamese border, future operation of Fengcheng (Phong Thanh) nuclear power plant (NPP) can raise many concerns about impact on marine environment in case a serious incident occurs. Based Delft3D modeling toolkit, calculation scenarios simulate spreading Cs-137 radioactive emission when level 7 occurs at Phong Thanh NPP have been set up according diff...
