This study focuses on the analysis of sandy beaches by integrating sedimentological, geomorphological, and geophysical investigations. The beach represents an extremely variable environment where different natural processes act simultaneously with human activities, leading to gathering methodologies Earth Sciences its evolution in space time. aim this research is propose a potential procedure f...

Coastal erosion and accretion along the Quang Nam coast in Vietnam have been increasing recent years, causing negative impacts on inhabitants local ecology. The Cua Lo estuary Nui Thanh district has a complex hydrodynamic regime owing to its connection with two estuaries three different tributaries. Therefore, detailed study of mechanisms processes these phenomena is crucial understand potentia...

The SiXianJiao (SXJ) is the first-order exchange node of West River and North redistributes water (mass) to downstream river network in Pearl Delta (PRD), South China. lateral SXJ waterway plays a critical role flow diversion between River, forming unique H-shaped compound node. Previous studies mainly focused on Y-shaped bifurcation confluence nodes, there lack research deltaic nodes. This stu...

Braided rivers exhibit highly variable morphologies, morphodynamic behaviours and resulting depositional records. To evaluate relationships between characteristics of braided-river channel belts river depth, water discharge streambed gradient, 39 numerical modelling experiments were conducted with the software Delft3D to simulate evolution under a broad range boundary conditions. Data from mode...

This paper investigates the impact of bridge-pilling modifications on tidal flow at strait a human-altered mesotidal estuary (Cádiz Bay, Spain). The analysis was accomplished by combining (1) field data current velocities in cross-section close to pile recently built bridge, and (2) hydrodynamics results from calibrated tested DELFT3D numerical model study site. focused bridge piling effects in...

Abstract Recent developments in process-based coastal area models such as XBeach provide new opportunities to predict responses primary forcing mechanisms storm hydrodynamic by using 2DH grids. However, due the lack of measured data, there are few application scenarios models. Therefore, more measurement and research needed. In this paper, Typhoon Lekima that hitting Zhejiang Province during ne...

Intertidal shoals are key features of estuarine environments worldwide. Climate change poses questions regarding the sustainability intertidal areas under sea-level rise (SLR). Our work investigates SLR impact on long-term morphological evolution unvegetated sandy in a constrained channel-shoal system. Utilizing process-based model (Delft3D), we schematize short tidal system rectangular (2.5 × ...

As an aggressive invasive salt marsh plant, Spartina alterniflora has been found to invade along tidal channel networks and threaten native ecosystems. Previous studies have established patterning correlations between S. invasion functions (drainage efficiency). However, a systematic analysis of in relation functional geometric features is still lacking. In this study, we extracted from remote ...

The mortality of infaunal bivalves (Venerupis corrugata, Cerastoderma edule, Ruditapes decussatus and philippinarum) due to a drop in salinity caused by extreme precipitation events estuarine areas has been analyzed within context climate change. Rías Baixas (NW Iberian Peninsula) were selected as representative area the environments where bivalve gathering is performed. Bivalve under was both ...
