“…All these phenomena, together with the predominant erosive activity of Pr ądnik itself, led to the creation of an irregular structure at the valley's bottom. Typical for Polish conditions, altitude systems of flood terraces cause the very rare access of flood waters to them [14][15][16]; however, being narrow, deeply indented and located in direct contact with the watercourse, the terrace of Pr ądnik can be more frequently influenced by the erosive activity of water. Geological bedrock is composed of limestones and upper Jurassic marls.…”

The numerical 1-D HEC-RAS modelling tool was supported by the estimation of the sieve curve changes procedure to measure the scale of predicted discharges along a stretch of stream in southern Poland on the Olkusz Upland. The procedure was calibrated in southern Poland on the mountain streams during high-stage events, using a radiotracer application in bedload transport. Particular terrain hypsometry, created by the dissolution of limestone, forced the deep erosion of the river valley bottom; it is here that the current shape of the riverbed of the Prądnik stream is placed. While numerical modelling is widely used in hydraulics, standards have been set for the estimation of flood risk zones; these estimations suggest that the densities of the measured cross-sections are less then optimal, and that the erosive processes are more frequent. This was proved by identifying a number of erosive sections. A new procedure proposed combining the prediction of grain size distribution with hydraulic modelling. Calculations using the estimation of sieve curves, based on the processes of creation and destruction in the armouring layer, have proven to be a challenge for the existing standards of hydraulic modelling. We believe that it is easy to expand the usefulness of the 1D model by utilising its results for this procedure. For the purpose of this type of analysis, dense cross-section measurements are involved, careful modelling is required and a wide range of additional in-field data has to be gathered. For the interpretation of the results, the relation between channel-forming discharge, bankfull discharge, present and critical shear stresses, as well as the mean diameter of the grain size and other estimated sieve curve parameters, were evaluated. Channel-forming discharge is smaller than the bankfull discharge in more than one third of the segment where the erosion process is more frequent and the stability of the riverbed is compromised. Channel-forming discharge was at least twice as high in the stable sections, compared to the erosive section. The presented method will help to find unstable riverbed sections, in order to mitigate the dimension of river training techniques and protect the natural state of the river. While we are in the period of development in this region of Europe, limiting the scope of interference in rivers and streams by applying this method may create an opportunity for the concept of river training close to nature.

“…According to Nahapiet [2010], that is why selected communities maintain a high level of inter -organizational linkages, and so they have easier access to resources and a much greater chance of success as a result of cooperation. The relational capital is also related to the positive attitude of enterprises toward the co -created relationship and their belief that the cooperation will be long -term [Zieliński, 2019].…”

Purpose – The purpose of the article is to analyse the importance of linkages and trust in business‑science cooperation. Moreover, the aim is to verify the impact of close business‑science relations on the innovativeness of the national economy. Research method – Literature studies, surveys, FGI (Focus Group Interview) Results – The research confirms the high importance of relations and relationship management in the development of business‑science cooperation. Companies that assess cooperation with science as valuable and significant to innovation, also indicate a high level of mutual relations and related fluidity in the exchange of knowledge. On the other hand, weak relations and low levels of trust often lead to problems in the implementation of joint projects, and, as a result, in the development of innovation. Originality / value / implications / recommendations – The processes of relationship development and trust‑building are as important in business‑science cooperation as the carefully conducted technology transfer. Thus, companies and scientific units engaged in mutual cooperation should pay attention to both of these factors. In macroeconomic terms, the level of relations between representatives of business and science affects the number of innovations created by a given economy. As a result, it also determines its innovativeness.
