W artykule przedstawiono możliwości wykorzystania modelu BIM w hydrotechnice na przykładzie istniejącej Elektrowni Wodnej na Dolnym Śląsku. Technologia BIM umożliwia opracowanie cyfrowych danych, które ułatwiają proces projektowania, koordynacji projektami oraz szybką wymianę danych. Do wykonania remontu Elektrowni Wodnej wykorzystany został program Allplan BIM, za pomocą którego stworzono kompleksowy model zawierający budynek elektrowni, kanał wlotowy wraz z ukształtowaniem spirali i kanał wylotowy oraz sąsiadujący z elektrownią budynek mieszkalny. Ukształtowanie przestrzenne elektrowni w BIM posłużyło do analizy hydraulicznej sprawności turbiny, która została wykonana w technologii CFD oraz usprawniła opracowanie projektu naprawczego.

The paper presents BIM technology and CDF model which were applied in hydraulic engineering studies. As a practical example a Hydroelectric Power Plant located in Lower Silesia was chosen. BIM technology enables the elaboration of digital data which facilitates the design process, project coordination and data editing. For the renovation of the Hydroelectric Power Plant AllPlan BIM software was used, with which a comprehensive model was created including: a powerplant building, an inlet channel with the spiral configuration, an exit channel and a residential building. Spatial configuration of the Power Plant in was used for hydraulic analysis of the efficiency of a turbine created in CFD technology. Finally, it was proved and showed in the paper that using BIM technology and CDF model improved and speeded up the renovation project.

When modelling flow and/or sediment transport in streams and rivers, one must frequently use the computer software of differing levels of complexity. The level of sophistication, accuracy, and quality of results are the parameters by which models can be classified as being 1D, 2D, or 3D; it seems certain that in the future, there will also be 4D and 5D models. However, the results obtained from very sophisticated models are frequently questionable, and designers in the field of hydraulic structures must have considerable experience distinguishing important information from irrelevant information. Thus, this paper aims to investigate the effect of the selected boulder block ramp hydraulic structure at Poniczanka stream on the bed-load transport. We evaluated sediment transport using the CCHE2D numerical model. We analysed several scenarios depending on the river bed type (erodible, non-erodible, rocky) and examined the rock blocks used for hydraulic structure construction. The obtained results were compared with the Hjulström and the Shields graph, which are a classic approach for identifying fluvial processes in river channels. In addition to these two methods, numerical modelling using the 1D HEC-RAS (Hydrologic Engineering Center’s River Analysis System) modelling were conducted, which included the determination of horizontal and vertical changes to the river bed morphology of the examined section of river reach as well as providing the basic hydrodynamics parameters which, from the practical point of view, designers involved in the process of designing ramps could use.

The aim of this research was to determine the influences of meteorological and hydrogeological factors on the water level of a rainwater storage and infiltration reservoir. The examined reservoir is located in the urban and industrial area of Krakow, on ground owned by the Polish State Railways (PKP), Kraków-Bieżanów branch. We analyzed a range of climatic (precipitation and evaporation) and hydrological factors (water stage in the reservoir and groundwater level) and their inter-relationships to determine their influences on the water depth regime in the storage and infiltration reservoir. Based on our results, the increase in the water table level in the reservoir is connected with the increase in the groundwater level and it is observed in the spring and summer periods, when meltwater and stormwater enter the reservoir. At the end of July, the groundwater table level increases because of excessive rainfall events. Throughout the entire experimental period, the reservoir was fed by infiltering groundwater from the upper parts of the basin. The water depth averages in the reservoir were closely correlated with the average groundwater table levels, the sum of precipitation from the week prior to the date of the examination of water depth in the reservoir, and the sum of potential evaporation in the given week.

The method based on original metric called Hydromorphological Index for Rivers (HIR) was developed in 2017 for the purpose of the monitoring of the hydromorphological status of flowing waters in Poland. It fulfils the requirements of the EU Water Framework Directive (WFD). It allows the assessment of both lowland rivers as well as mid-altitude and highland streams. The proposed system can be used to assess the natural and heavily modified rivers as well as artificial channels. The basis of the proposed system is a field survey, which is supplemented by the analysis of Geographic Information Systems (GIS) data and remote sensing materials. The analysis of the GIS data and remote sensing materials already enable to estimate preliminary classification of the hydromorphological status of the non-surveyed water bodies. On the basis of the field survey, the principal HIR value can be estimated for the considered river site and comparing with the reference conditions, the hydromorphological quality status in the five-class system can be calculated. The properly selected, representative survey sites (one or more depending on the heterogeneity of the environment), enable the classification and evaluation of entire surface water bodies in the framework of the national environmental monitoring. The GIS component of the HIR proved to be useful in verifying the determination of heavily modified water bodies and in assessing the needs of river restoration. It was also applied in the development of the National river restoration program for predicting the impact of the proposed restoration measure on the state of hydromorphology.

The purpose of this research was to examine the impact of body composition on the anaerobic ability to generate strength and power produced separately by upper and lower limbs during dry-land and in-water (propulsion force) tests. Further examination included the influence of all gathered anaerobic strength indices on the results of 100-m front crawl race. Methods: The study involved 26 male swimmers (age: 19.8 ± 2.48 years). Fat-free mass, total body water and muscle mass of arms, legs, and trunk were measured. Dry-land average work, maximal power generated in 40-second arm-cranking test, and work generated in 20 countermovement jumps were evaluated. The forces generated separately by arms and legs were assessed during 40-second tethered swimming. All indices of body composition were found strongly correlated with indices of average work and maximal power generated by arms and legs in dryland tests. Results: Muscle mass of arms and trunk moderately and strongly (r = 0.44–0.64) influenced the force generated by arms in tethered swimming. There was no significance in the relationship of leg muscle mass and force generated by legs in tethered swimming. Significant relationships were observed between the results of the 100-m front crawl and the muscle mass of the arms, trunk, legs, as well as the average work and maximal power in the arm-cranking test (r: 0.39–0.54). The average impulse of arm force and maximal leg force in tethered swimming moderately and significantly correlated with 100-m swimming results. Conclusions: The study concludes the relevance of developing muscle mass balanced to the body size, which is involved in propulsion force production in sprint front crawl swimming.

W pracy przeanalizowano grubości kamieni użytych do budowy ubezpieczenia w postaci narzutu kamiennego oraz jego podsypki na dwóch obiektach w okolicy Starego Sącza oraz we wsi Głębokie (w trakcie budowy). Zestawienie poszczególnych pomiarów i przedstawienie tych wyników w postaci krzywych przesiewu, a następnie sprawdzenie warunków stateczności i przepuszczalności pozwalają określić, czy parametry charakteryzujące rozmiar podsypki i kamienia łamanego budującego umocnienie zostały poprawnie dobrane. Pomiary narzutów i podsypki wykonano za pomocą metody Wolmana – pomierzono 600 próbek. Po wykonaniu obliczeń ustalono, że oba warunki stateczności zostały spełnione tylko przez narzut w miejscowości Głębokie, natomiast warunek przepuszczalności nie został spełniony w żadnym narzucie. Z przeprowadzonych obliczeń wynika, że konieczna byłaby zmiana kruszywa o minimalnej średnicy w podsypce filtracyjnej tak, aby został spełniony warunek przepuszczalności. Występuje tu największa różnica pomiędzy minimalnym rozmiarem spełniającym warunek a obecnie zastosowanym kamieniem łamanym. Zwiększenie tej średnicy pozwoli na spełnienie także innych warunków.
