Multi-temporal analysis is one of the main applications of remote sensing, and Landsat imagery has been one of the main resources for many years. However, the moderate spatial resolution (30 m) restricts their use for high precision applications. In this paper, we simulate Landsat scenes to evaluate, by means of an exhaustive number of tests, a subpixel registration process based on phase corre...

BACKGROUND Coastal landscapes are being transformed as a consequence of the increasing demand for infrastructures to sustain residential, commercial and tourist activities. Thus, intertidal and shallow marine habitats are largely being replaced by a variety of artificial substrata (e.g. breakwaters, seawalls, jetties). Understanding the ecological functioning of these artificial habitats is key...

Abstract. The ongoing phenomenon of climate change is leading to an upsurge in the number extreme events. Territories must adapt these modifications order protect their populations and properties present coastal areas. adaptation areas also aims make them more resilient future In this article, we examine two strategies for adapting risks: holding line through hard constructions such as seawalls...

Abstract Waves overtop berms and seawalls along the shoreline of Imperial Beach (IB), CA when energetic winter swell high tide coincide. These intermittent, few-hour long events flood low-lying areas pose a growing inundation risk as sea levels rise. To support city response management, an IB warning system was developed. Total water level (TWL) forecasts combine predictions tides sea-level ano...

Abstract Understanding the spatiotemporal dynamics of trophic structures, or trophodynamics, is important for assessing overall condition and function estuarine ecosystems. We examined spatial seasonal trophodynamics nekton assemblages across seascape a subtropical estuary (Charlotte Harbor, FL, USA) using historical data from an ongoing monitoring program. also relationships between distributi...

Coastal reclamation is becoming a common land restoration trend all over the world as result of rising demand for land. Though restoring coastal wetlands has significant economic advantages, slew adverse ecological effects threatens carbon functions wetlands. For objective making appropriate use policymaking, ecological-economic trade-offs initiatives must be carefully considered. In this study...

Sandy nourishments can provide additional sediment to the coastal system maintain its recreational or safety function under rising sea levels. These be implemented at sandy beach systems, but also used reinforce gray infrastructure (e.g., dams, dikes, seawalls). The Hondsbossche Dunes project is a combined shoreface, beach, and dune nourishment of 35 million m3 sand. was built replace flood pro...

Abstract Biodiversity is increasingly understood as an important mediator of human aesthetic appreciation scenes and landscapes, with implications for cultural services well‐being. However, the generality biodiversity effects across affective emotions, scales habitats remains unclear. Urban coastal intertidal on seawalls other artificial structures are expanding worldwide. Despite growing calls...

In densely populated coastal areas with sea-level rise (SLR), protecting the shorelines against erosion due to wave impact is crucial. Along many engineered structures like seawalls and breakwaters, there are also green constructed oyster reefs (CORs) that can not only attenuate incident waves but grow maintain pace SLR. However, a lack of data understanding long-term attenuation capacity livin...
