This paper presents an integrated hydraulic, energy and economic analysis of two diversion-system alternatives for the small hydropower plant “Merćez” on the Lukovska River. Two technical concepts are considered: Alternative I – water conveyance through a pressurized steel pipeline, and Alternative II – an open-channel diver...

Geotechnical monitoring represents a key component in preserving the stability and safety of structures and the route of an expressway, especially in complex terrain conditions such as peatlands and saturated soils. This paper analyzes an integrated monitoring system along such a route, which includes tracking settlements, pore pressures, and horiz...

Recent advances in 3D reconstruction techniques, including Terrestrial Laser Scanning (TLS), SLAM-based systems, and mobile LiDAR, have improved heritage documentation practices. This study evaluates the geometric accuracy of Leica BLK360, GeoSLAM ZEB-REVO, FJD TRION™ S1, and iPhone 12 Pro using a UNESCO-listed Byzantine Bath monument, with F...

Runoff modelling in karst areas represents a specific challenge, due to inherent complexity and uncertainty of underground flow paths. Utilization of physical relationships to describe the individual components of the runoff requires a much more detailed understanding of the conditions in the basin. However, the application of such models, with an ...

This study analyzes the need to transform the traditional two-dimensional cadastre in the Republic of Srpska into a multidimensional system (3D/4D). The research aims to examine the compliance of the current real estate records with the international standard ISO 19152 (LADM) and to identify the key prerequisites for introducing the third and fourt...

A theoretical model for porous viscoelastoplastic (VEP) materials under dry conditions is examined based on the principles of mass and energy conservation using rheological-dynamical analogy (RDA). The model provides the expressions for the creep coefficient, Poisson's ratio, modulus of elasticity, damage variable and strength in the function of po...

Two approaches for beam-to-beam contact modeling are considered in the paper. The first is the classic continuum approach with point-to-point contact discretization. The other is the coarsegrained approach where the physical intermolecular fields are applied for the modeling of interaction of continuous bodies. To describe the contact, the repulsiv...

Trebinje is a city with a rich cultural and historical heritage associated with influential historical figures who have played a role in its physical construction and contributed to its identity. Legends about these people are a part of the city’s rich intangible cultural heritage and they can provide a solid basis for city branding. This pa...

The detection of erosion was carried out on a characteristic rocky pillar, with the localization and quantification of differences between two surfaces. For this purpose, based on the defined area and spatial configuration of the scanning object, scanner positions, arrangement of control points, and appropriate spatial scanning resolution were plan...

The transition from ellipsoidal geodetic coordinates to rectangular 3D coordinates is quite simple, while the reverse procedure is somehow more complex due to the mathematical relationship between the ellipsoidal width and 3D coordinates. Until now, several methods for solving this problem have been defined and described in geodetic literature. In ...
