“…2b), the measurement result in 1997 significantly differs from the actual trend; this particular measurement probably did not include the total discharge in this gauging station. Similar conclusions were reached (after consultation with the PSHM measuring team) in the measurement of floods in 2010, resulting from the lack of measurement of a part of the discharge over the road flood bank on the right-side flood terrace (Banasiak and Krzyżanowski, 2015b). The verified flood flows in 2010, that is the measured discharge and peak discharge in this and the neighbouring water gauging stations in Opole and Koźle, confirm the KNP for Krapkowice obtained from the 2-D model calculations.…”

“…2-4). Based on the simulation, rating curve was obtained, which together with the results of hydrometric measurements, in particular the verified results for the flood in May 2010 (Banasiak and Krzyżanowski, 2015b), and the approximate flow rate curve, makes it possible to determine the flow for the maximum level H max during the floods in July 1997 for selected cross-sections.…”

Aim of the studyThis paper presents a verification of peak discharges (maximum flow) of the great flood that took place in July 1997 on the Odra (Oder) river, for the section between Racibórz and Słubice. Material and methodsThe carried out analysis included a review of hydrological and morphological data, GIS analysis, extensive hydrodynamic two-dimensional modelling, and determination of rating curves for gauging stations. Results and conclusionsIt has been found that previously published peak discharges for the 1997 flood need to be altered to a significant extent. For instance, the maximum discharge in Wrocław is estimated to have reached ca. 3900 m 3 • s -1 versus 3640 m 3 • s -1 as previously believed, while for the upstream Nysa Kłodzka station, the maximum discharge estimate had to be raised from 3530 m 3 • s -1 to 4300 m 3 • s -1 . On the other hand, for the section below Ścinawa station, the peak discharges were significantly overestimated, even by 1000 m 3 • s -1 , which is up to 50% of the actual flow. The determined values are hydrologically and hydraulically consistent, i.e. following the law of flow continuity, considering tributary supplies, flood bank breaches, and retention capacity of the river valley.

“…A graphical rating curve helps in representation the relationship and to transform stages to discharges [3,4,5,6,7]. The extreme discharges and water levels are the most relevant hydrologic river data about the floods [8,9,10]. The floods cause a calamitous impact for the people, economy, and environment every year.…”

In the designing water reservoirs, information on flood control it’s necessary to make the right technical decisions related to the safe use of reservoirs, human life and the natural environment in the areas below the reservoirs.The hydrological data of a given river profile (stages and discharges) is important for the planning, hydraulic modeling of the reservoir and its exploitation. In the last years of the twentieth and twenty-first century in Central Europe, many floods of different intensity and extent have occurred on the Odra River and its tributaries. Therefore, the increasing extreme natural phenomena, like a violent floods and long droughts, mean that the importance of hydrotechnical constructions increases. One of the planned investments, which is to minimize the effects of the flood by collecting a flood wave on the Osobłoga River is the dry dam named Racławice Śląskie. According to Polish law, model researches are required for the 1st and 2nd class of hydrotechnical constructions. Considering research models, not only physical models are used, but also hydroinformatic programs for the numeric model, like HEC-RAS. These programs enable modeling based on hydrometric measurements of rivers. The aim of the work is to model the discharges using the HEC-RAS program after analysis of the hydrological data. Analyzes and modeling were made of the planned reservoir – the dry dam across the Osobłoga River, Racławice Śląskie profil in the Opolskie Province, in Poland.

“…In the case of analysis of floodplains and emerged channel landforms, methods based on LIDAR (Light Detection and Ranging) laser scanning (aerial laser scanning (ALS) and terrestrial laser scanning (TLS)) are useful. Echo sounders integrated with GNSS (Global Navigation Satellite Systems) receivers [29] and acoustic Doppler current profiler (ADCP) devices [30,31] enable examining the main channel and other landforms filled with water.…”

River valleys of the Central European Lowlands are the zones of the highest dynamics of morphogenic processes. In the case of areas affected by glacial processes, despite their lowland nature, often they also have a complex geological structure. Sub-alluvial bedrock, composed of erosion-resistant deposits, commonly forms morphological protrusions within them. Their presence significantly affects both the course of flood flows and the valley floor relief. Effective forecasting of fluvial processes in such valley reaches requires conducting research within the entire geomorphologically active zone, both in the channel and the floodplain. The effectiveness of such research should be enhanced by simultaneous use of several different remote sensing methods, including short-range remote sensing. The verification of this hypothesis was the aim of the presented works. Such methods were used in the study of morphodynamics of a Bug valley reach. This area is characterized by a complex geological structure. High-resolution multispectral satellite images (VHRs) and a digital elevation model (DEM) based on aerial laser scanning (ALS) were used to examine the terrain relief. The morphology of the river channel itself was determined based on a series of bathymetric measurements made by a research team. Due to induced climate change and increasing maximum flow values, it can be assumed that the effect of a geological structure in the Central European Lowlands will play an increasing role. The threat and losses associated with floods will also increase. Rational flood prevention requires improvement of remote sensing research methods in lowland river valleys, especially those with complex geological structures. The valley reach presented in this article is an example of such a landform.
