Using airborne drones to monitor water quality in inland, transitional or coastal surface waters is an emerging research field. Airborne can fly under clouds at preferred times, capturing data cm resolution, filling a significant gap between existing situ, and satellite remote sensing capabilities. Suitable lightweight cameras are readily available on the market, whereas deriving products from captured image not straightforward; vignetting effects, georeferencing, dynamic nature high light...
The INSPIRE Horizon Europe project aims to combat plastic pollution in rivers by deploying 20 scalable technologies designed prevent and remove litter. These innovative solutions will be demonstrated across six Europe. A key component of the involves monitoring on their banks establish a baseline assess effectiveness implemented technologies.One introduced is camera- drone-based system for tracking flux measuring macroplastic densities riverbanks. fixed camera utilizes series Commercial...
The occurrence of litter in natural areas is nowadays one the major environmental challenges. uncontrolled dumping solid waste nature not only threatens wildlife on land and water, but also constitutes a serious threat to human health. detection monitoring affected by pollution thus utmost importance, as it allows for cleaning these guides public authorities defining mitigation measures. Among methods used spot littered areas, aerial surveillance stands out valuable alternative relatively...
Oil spills in ports are particular cases of oil pollution water environments that call for specific monitoring measures. Apart from the ecological threats they pose, their proximity to human activities and financial losses induced by disturbed port add need immediate action. However, ports, established methods based on short-wave infrared sensors might not be applicable due relatively low thickness layer, satellite images suffer insufficient spatial resolution, given agglomeration objects...
Dredging operations are essential to protect coastlines, safe navigation and ensuring access harbours. With threats of sea level rise, flooding more extreme storms, the need for dredging will only increase their sustainable implementation be key.One key aspects control during dredging, is release sediments in water turbidity which can degrade quality harm sensitive ecosystems. Imposing limits where contractors have comply with, common most parts world. However, there various sources near...
In this work, we studied the potential of visible, near-infrared, and shortwave infrared wavelength regions for monitoring oil spill incidents using optical reflectance. First, a simple physical model was designed accurate thickness volume estimation The developed method made invariant to changes in acquisition illumination conditions. next step, an algorithm based on artificial neural network detect spilled oil. training samples that are required optimize parameters were generated by...
Intertidal bars are common features on meso-and macro-tidal sandy beaches with low to moderate wave energy environments. Understanding their morphodynamics is, hence, crucial for enhancing our knowledge beach processes which is beneficial coastal management. However, most studies have been limited by assessing bar systems two-dimensionally and typically over the short-term. Morphology dynamics of an intertidal system in a environment investigated using bi-annual LiDAR topographic surveys...
In June 2023 the Horizon Europe project INSPIRE kicked off. will fight against plastic pollution in rivers by introducing 20 scalable technologies to prevent and eliminate litter.

Intertidal bars are common features of sandy beaches in meso- and macro-tidal environments, yet their behaviour under storm impact subsequent recovery remain poorly documented. Intensive surveys provide valuable information; however, it takes time to process the vast amount data.

Sandy beaches play an important role for economic and recreational activities as well coastal protection. Storm impact recovery involve complex dynamic processes from short to longer-term. These result in a broad range of morphological change which can be assessed remote sensing such airborne LiDAR (Light Detecting Ranging) system. This study monitors the response sandy multi-barred beach after severe storm. A new algorithm automated bar extraction developed Python is applied digital surface...
Abstract. Sustainable management of the coastal resources requires a better understanding processes that drive coastline change. The is highly dynamic sea-terrestrial interface. It affected by forcing factors such as water levels, waves, winds, and highest most severe changes occur during storm surges. Extreme storms are drivers responsible for rapid sometimes dramatic coastline. consequences impacts from these events entail broad range social, economic natural resource considerations...

Although airborne drones are used frequently for agricultural, biodiversity and other applications, it's use water quality monitoring is relatively new. There a couple of additional complexities, including unknown optical properties, atmospheric contribution need direct georeferencing. This paper describes the MapEO-water service, which cloud-based service to derive water-leaving reflectance derived products (chlorophyll-a, turbidity presence marine litter/plastic). Specific attention will...
