This study presents a vulnerability assessment methodology that was developed to analyze the Croatian Eastern Adriatic Coast (CEAC), which has extremely complex geomorphology. Local coastal retreat, slope instability phenomena, and influence of marine erosion play significant role in geohazards southeastern area Krk Island (Kvarner area, northeastern channel part Sea). Recent studies emphasize need develop an adequate monitor its evolution define risk management strategies. The analysis...

The importance of skid resistance performance assessment in pavement engineering and management is crucial due to its direct influence on road safety features. This paper provides a new approach predictive model definition based experimentally obtained texture roughness parameters. originally developed methodology photogrammetry technique for surface data acquisition analysis, named the Close-Range Orthogonal Photogrammetry (CROP) method. Texture features were analyzed profiles extracted...

The coastal area around the settlement of Stara Baška (Krk Island, NE channel zone Adriatic Sea) is in a delicate geodynamic balance. main causes are geological structure, hydrological and hydrogeological conditions direct exposure coast to waves storm surges. In this paper, effects expected sea level rise on vulnerability investigated. Detailed field research was conducted. complex morphology surveyed using an Uncrewed Aerial Vehicle (UAV), UAV-derived data used as 3D point cloud orthophoto...

The limitations of the classical wavemaker theory motivated development a new equation that can directly predict both regular and broken waves based on flap-type setup. This is achieved first by coupling commonly accepted wave breaking formula with linear equation. Both these equations were then rewritten in terms paddle stroke, water depth, frequency instead number. Additionally, validity range for each was explicitly defined to maximum height before breaking. Comparison measurements...

Monitoring and analysis of changes in the volume area nourished beaches is crucial to inform any beach renourishment programme. The aim this study utilise UAV surveys SfM photogrammetry assess nourishment performance an artificial gravel exposed a range external forcing, including storms. paper presents results from nineteen conducted between January 2020 2021 at Ploče, Rijeka (Croatia). was twice eleven storm events, ranging weak strong, were recorded during period.

Large landslides triggered by rainfall and floods were registered on both sides of the Rječina River Valley, near City Rijeka, in Croatia, where numerous instability phenomena past 250 years have been recorded, yet only some locations investigated. The paper presents investigation dormant landslide located south-western slope, recorded historical descriptions from 1870. Due to intense long-term rainfall, was reactivated 1885, destroying damaging houses eastern part Grohovo Village. 2D...

The Plitvice Lakes National Park is inscribed on UNESCO’s World Heritage List. lake system composed of 16 cascading lakes different sizes separated by tufa barriers, which are the park’s key phenomenon. characterized highly diverse trends characteristic hydrological indicators—mean annual water levels, discharges, and barrier growth. analyses carried out in this paper identified that period before early 1990s, Kozjak Lake had a trend decreasing together with increasing levels growing...

This paper analyzes the origins of two tombolos (one recent and another fossil/submerged) on southwestern coast Prvić Island, which is located in Kvarner area northeastern part Adriatic Sea.A tombolo Cape Pipa was formed by erosion Quaternary deposits Palaeogene siliciclastic rocks.The submerged much bigger, clearly visible sea bed toward southwest.The conditions for forming a have occurred during slow rise then stagnation level Sea Holocene.The flooded fossil probably final period rapid...

: Abstract Beach nourishment is now widely used as a "soft" coastal protection but its performance still relatively poorly understood. monitoring allows analysis over range of environmental conditions which, in turn, can provide the basis for successful design and implementation. Remote sensing techniques based on Structure-from-Motion (SfM) have been successfully geomorphological studies environments, including gravel beaches (James et al., 2013). This paper presents applications SfM to two...

The selection of an appropriate coastal protection structure using multi-criteria analysis method AHP (analytic hierarchy process) was presented by a case study beach reconstruction in the Kostanj Bay (north-western part Croatia). newly designed (about 300 m long) will be formed on western bay additional filling natural rocky coastline with gravel and building reinforced concrete seawalls towards sea. protected submerged breakwater. Five different alternatives were analysed defined design...

Coastal areas are becoming increasingly vulnerable due to climate change. These regions exposed various sources of flooding, such as high sea levels, river discharge and heavy rainfall. Our study focuses on understanding compound flooding from storm surges in Croatia. This is the first floods this country. For purpose, we analysed time series water levels discharges hydrological stations located along ten major coastal rivers. Since there only a limited number tide gauges Croatia, combined...
