“…Thus, the experiments must be well-designed and the applied measurement technique so sophisticated that all possible mobilizations can be observed and determined accurately. In principle, the movement of the ordnance can be tracked by video recording and subsequently analyzed by image analysis techniques, such as those described in Baselt [40].…”

Landmines and explosive remnants of war are still present in the Western Balkans and remain a deadly legacy of the hostilities at the end of the 20th century. Over the years, several incidents have occurred in Bosnia and Herzegovina, in Serbia, and in Croatia where intact ordnance has caused injuries and fatalities. Floods, torrential flows, and gravitational mass movements pose a particular threat. Landmines and explosive remnants of war are mobilized and displaced into previously uncontaminated areas. We first discuss the historical and technical background of this hazardous situation. We then show which hydro-morphological processes are responsible for the mobilization and displacement. We then illustrate how a prediction of the likely contaminated areas can be obtained. We show that the problem can only be tackled using a stochastic-deterministic model. However, for the eventual development of risk-hazard maps, preliminary work using laboratory experiments and field surveys is required. The article, therefore, proposes a novel approach to the problem in an international research project. The aim would be to produce risk-hazard maps that can be used by elected decision-makers, administrative authorities, and emergency personnel in affected municipalities.

“…This research aims to enhance an analytical or numerical (3-D) framework and propose a mathematical scheme to start predicting bed level changes near earth dams, where factors like complex geometry, flow pattern, downdrafts, and sediment density distribution have a major effect on simulation results. [1]. This study is an example of an application study, in which mathematical knowledge is used to create an accurate simulation of a natural process.…”

Modelling the Velocity Distribution around the Hydraulic Structure

Intense pressure and velocity oscillations, as well as extensive air entrainment, make the investigation of the hydraulic leap created in stilling basins very difficult. Its intricacy, coupled with the real-world need for stilling basins to dissipate energy, puts physical modelling front and center. Despite stilling basins' essential role in engineering, bibliographic research has often focused primarily on the more familiar case of the classical hydraulic leap. Thus, a physical model of a typical USBR II stilling basin was used to investigate the features of the hydraulic leap in this work. Under this framework, the model investigated the hydraulic jump's free surface profile and velocity distribution. A series of experiments were conducted to compare the efficacy of modern tools like the time-of-flight camera with that of more conventional ones like the Pitot tube. Notwithstanding some of the stated constraints, the findings demonstrated a good depiction of the free sample surface and the velocity distribution. In addition, the used instruments demonstrated the substantial impact the energy dissipation devices had on the flow parameters. In comparison to traditional hydraulic leaps, significant variations in hydraulic jump form and maximum velocity locations within recorded vertical profiles were discovered.
