The assessment and mapping of riverine flood hazards risks is recognized by many countries as an important tool for characterizing floods developing management plans. Often, however, these plans give attention primarily to open-water floods, with ice-jam being mostly afterthought once have been drafted. In some Nordic regions, can be more severe than floodwater levels often exceeding the same return periods. Hence, it imperative that flooding due river ice processes considered in This also...
This paper presents a new approach for delineating river coastlines in RGB close-range nadir aerial imagery acquired by unmanned vehicles (UAVs), aimed at facilitating waterline detection through the reduction of dimensions colour space and use coarse grids rather than pixels. Since water has uniform brightness, expressed as value (V) component hue, saturation, (HSV) model, question is attained extracting V investigating its histogram to identify areas where does not vary considerably. A set...
Flood management is very important task in the context of rapid climate changes. Increasing frequency extreme weather and fluvial phenomena, such as droughts, water shortages or floods determines that detecting bodies boundaries between them surrounding surface an challenging issue. We elaborated a new approach for delineating river coastline based only on close-range RGB nadir images acquired by means UAV (unmanned aerial vehicle), converted to HSV (hue, saturation, value) color space. used...
In frame of the project no. 2020/38/E/ST10/00295 carried out within Sonata BIS programme, financed by National Science Centre Poland, we consider different approaches to delineate river coastline based only on close-range visible light aerial images (RGB) acquired unmanned vehicles (UAVs).  Among scrutinized methods, use automatic mapping extent water bodies  means image classification. It was found that best results reconstructing inundation (even 95%) were obtained using...
