NavTEL is a new decision support tool for the short-term (36 h) planning of ship routes and management underkeel clearance in estuarine navigation channels. uses deterministic method coupled with TELEMAC-MASCARET system numerical modeling hydrodynamic sediment transport estuary two-dimensional approach. In its present version, allows (i) daily simulations to be automatically prepared launched; ...

The Icó-Mandantes Bay is one of the major branches of the Itaparica Reservoir (Sub-Middle São Francisco River, Northeast Brazil) and is the focus of this study. Besides the harmful algae blooms (HAB) and a severe prolonged drought, the bay has a strategic importance—e.g., the eastern channel of the newly built water diversion will withdraw water from it (drinking water). This article presents t...

Sufficiently accurate and low-cost estimation of tidal velocities is of importance when evaluating a potential site for a tidal energy farm. Here we suggest and evaluate a model to calculate the tidal velocity in fjord entrances. The model is compared with tidal velocities from Acoustic Doppler Current Profiler (ADCP) measurements in the tidal channel Skarpsundet in Norway. The calculated veloc...

This study investigates the effects of vegetation patch patterns on morphological evolution alluvial river channels at reach-scale. For this, a new two-dimensional numerical biomorphodynamic model has been developed using Telemac-Mascaret system. Considering newest development in topic, bedload transport are included by extending Einstein's parameters for sediment formula. The was subsequently ...

This study attempts to model sediment transport rates and the resulting bed evolution in a complex estuarine environment: the Gironde estuary, characterized by a high hetereogeneity in the sediment bed composition, with the presence of both cohesive and non-cohesive sediments and sand/mud mixtures. Our main objective is to extend an existing 2D morphodynamic model developped by Huybrechts et al...

Abstract Migration from fresh water to the marine environment is a crucial, transitional stage in development of Atlantic salmon (Salmo salar). This study used combination acoustic tracking, instrument data, and hydrodynamic modelling examine behaviour juvenile (smolts) during their transition environment. The focuses on high-energy coastal northern Scotland, which currently being developed for...

Abstract In recent years, with the acceleration of climate change and urban modernization, flood risk economic social development has increased. The problem disasters needs to be solved urgently. It is particularly important conduct disaster loss assessment research for further control reduction, emerging big data have opened a new direction solving flooding. this study, Qianshan River Basin in...

Coastal areas of Grenada in the south-eastern Caribbean are particularly vulnerable to adverse impacts climate change. The effects increasingly powerful hurricanes, sea-level rise, and reef degradation often compounded by local anthropogenic activities. Many communities reside low-lying areas, with development infrastructure concentrated along coast. Wave/storm surge models based on historic hu...

In recent years, society has become more aware and concerned with the environmental human health impacts of population growth urbanisation. response, a number legislative measures have been introduced within Europe (and globally), which sparked much cross-disciplinary research aimed at predicting quantifying these impacts, suggesting mitigation measures. response to such this paper is focused o...
