Contribution to the Optimization of Quantitative and Qualitative Parameters of the Composition of Slag Aggregate Permeable Concrete SIČÁKOVÁ Alena1,a*, KOVÁČ Marek2,b 1Technical University of Košice, Faculty of Civil Engineering, Vysokoškolská 4, 042 00 Košice, Slovakia 2Danucem (a CRH Company), 040 01 Košice, Slovakia aalena.sicakova@tuke.sk, bmarek.kovac@sk.crh.com Keywords: permeable concrete, air-cooled blast furnace slag aggregate, binder, hydraulic conductivity, void content, compressive strength Abstract.
Although the free CaO that tends to be present in this type of aggregate can cause volumetric changes, Li [15] reported that after long-term exposure to external weathering, the effect of this expansion on engineering use is usually negligible

HEC-RAS (Hydrologic Engineering Centers River Analysis System), is a hydraulic modeling software package designed to simulate flow in rivers and canals.
This system enables hydraulic engineers to analyze flows in riverbeds and determine flood zones.
In addition, the model offers the possibility of reducing calculation time by implementing a coarser mesh over fine topographic details using a so-called sub-mesh bathymetric approach [28]. 3.1.2 TELEMAC-2D The TELEMAC-2D model is widely used in coastal and other large-scale storm surge simulations [29], but it’s widely used in civil and environmental engineering studies, particularly for applications related to water resource management, flood modeling, and ecosystem modeling [30].

Steady incoming flow over bluff obstacles is ubiquitous and of great interest in both engineering applications and fundamental fluid mechanics.
For many engineering design structures, vortex shedding will result in unnecessary structural movement known as the flow-induced vibration.
The use of transport type of governing equations for turbulence models has been the standard practice for many designers and engineers.
