Abstract This paper represents the result of IAEG C35 Commission “Monitoring methods and approaches in engineering geology applications” workgroup aimed to describe a general overview unmanned aerial vehicles (UAVs) their potentiality several applications. The use UAV has progressively increased last decade nowadays started be considered standard research instrument for acquisition images other information on demand over an area interest. cheap fast solution on-demand detailed interest...
In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity biodiversity capable supporting commercial fisheries. We investigated the origin this apparent enhancement over a segment North Mid-Atlantic Ridge (MAR) using sonar, corers, trawls, traps, remotely operated vehicle survey habitat, biomass, biodiversity. Satellite remote sensing provided information on flow patterns, thermal fronts, primary...
Abstract The Schmidt hammer is a useful tool applied by geomorphologists to measure rock strength in field conditions. essence of application obtain sufficiently large dataset individual rebound values, which yields meaningful numerical value mean strength. Although there general agreement that certain minimum sample size required proceed with the statistics, choice (i.e. number impacts) was usually intuitive and arbitrary. In this paper we show simple statistical method, based on two‐sample...
Abstract. We elaborated a new method for observing water surface areas and river stages using unmanned aerial vehicles (UAVs). It is based on processing multitemporal five orthophotomaps produced from the UAV-taken visible light images of nine sites river, acquired with sufficient overlap in each part. Water are calculated first place, subsequently expressed as fractions total water-covered terrain at given site recorded dates. The logarithms later calculated, producing samples, consisted...
Abstract This paper reports on the performance of a novel system for supporting search and rescue activities, known as SARUAV (search unmanned aerial vehicle), in field experiment during which real‐world scenario was simulated. The took place March 2–3, 2017, at two sites located southwestern Poland. Three groups acted experiment: (1) vehicle (UAV) operators, (2) ground searchers, (3) participants who simulated being lost. In uncomplicated topography without snow cover, identified lost...
Abstract The application of linear interpolation for handling missing hydrological data is unequivocal. On one hand, such an approach offers good reconstruction in the vicinity last observation before a no-data gap and first measurement after gap. other it omits irregular variability data. Such irregularity can be described by time series models, as instance autoregressive integrated moving average (ARIMA) model. Herein, we propose method which combines with model (ARI, i.e. ARIMA without...
Recent advances in search and rescue methods include the use of unmanned aerial vehicles (UAVs), to carry out monitoring terrains spot lost individuals. To date, such searches have been conducted by human observers who view UAV-acquired videos or images. Alternatively, persons may be detected automated algorithms. Although some algorithms are implemented software support activities, no successful case using detectors has reported on thus far scientific literature. This paper presents a...
This study is the first attempt to assess accuracy of water levels measured by Sentinel-3A altimetry at virtual stations (VS) located along Polish rivers. The studied rivers (Vistula, Odra, Warta, Bug, Narew, San) drain predominantly lowlands, and – based on width can be classified as small medium (40–610 m in width). assessment a comparison between level anomalies from 34 VS data nearest adjacent gauges, acquired April 2016 August 2019. time lags series (VS vs. gauge) are estimated so that...
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...
River basins located in the Central Sudetes (SW Poland) demonstrate a high vulnerability to flooding. Four mountainous and corresponding outlets have been chosen for modeling streamflow dynamics using TOPMODEL, physically based semi-distributed topohydrological model. The model has calibrated Monte Carlo approach—with discharge, rainfall, evapotranspiration data used estimate parameters. overall performance of was judged by interpreting efficiency measures. TOPMODEL able reproduce main...
This study is the first attempt to investigate bias of Sentinel-3 altimetry measurements over rivers resulting from satellite ground track shift and associated river slope. Altimetry-based water levels are measured at so-called virtual stations (VS), which defined as area where pass intersects with a channel. Since tracks satellites can up 1 km away nominal track, calculated heights VS correspond different locations on river. However, all given combined into one time series levels, assigned...
The Mid Atlantic Ridge (MAR) has been identified as an important component of the lower bathyal (800−3500 m depth) benthic biogeographic province in North Ocean. We performed a multi-scale characterization seafloor topography MAR. In basin-scale analysis, we have used 30″ General Bathymetric Chart Oceans (GEBCO) grid to estimate area different components habitat main basin and produce corresponding depth–area relationship. regional-scale investigation is based on swath bathymetry surveys...
Despite ubiquitous warming, the lower Oder River typically freezes over almost every year. Ice jams may occur during freeze-up and ice cover breakup phases, particularly in middle reaches of river, with weirs piers. The slush blocks accumulate to form jams, leading backwater effects substantial water level rise. small bottom slope tidal backflow from Baltic Sea enhance formation cold weather conditions, jeopardizing dikes. Therefore, development an jam flood forecasting system for is much...
A new system for computing the multimodel ensemble predictions of water levels, known as HydroProg, is applied in process real-time modelling and forecasting riverflow upper Nysa Kłodzka basin (SW Poland). The HydroProg automatically produces early warnings against high flows on a basis prognoses from external hydrologic models which are run cloud-like fashion using hydrometeorological observations. offered by serve members become inputs to does data pre- post-processing well computes...
We propose a simple geometrical approach for delineating region above which an Unmanned Aerial Vehicle (UAV) should fly to support the Search and Rescue (SAR) activities. The procedure is based on concept of crow's flight distance travelled by lost person its probability distribution, areas in there does not exist any SAR database that can be used estimate parameters such distribution. novelty lies indirect character, namely we do these but seek regions reveal comparable topographic settings...
