“…During the last 50 years, there have been recordings of increased frequency, intensity, and magnitude of floods [1][2][3]. For this particular reason, many states have started to implement new and modern monitoring systems as part of flood protection programs and also allocate funds for studies that address damage mitigation through the use of mathematical, geospatial models that can accurately predict and identify areas affected by potential floods [4][5][6]. The increase in frequency of flood occurrence can also be correlated with urban and rural expansion, with special attention given to flood-prone areas.…”

The development of human society over the past century has led to an explosion in population numbers and a migration of settlements to river valleys, which have become increasingly exposed to the risk of flooding. In this context, the scientific community has begun to work on identifying mathematical and spatial models that can help to identify areas at risk as quickly as possible. The present article is one that follows this objective, proposing an automatic model that can be implemented in ArcGIS and that aims to identify only areas at risk of flooding using a single file, the DEM. The novelty of this article and the usefulness of the method are given precisely by the fact that it is possible to quickly find out which areas may be exposed to flooding, i.e., water accumulations, only based on relief, which is extremely useful for local authorities. The analysis was conducted on all hierarchy orders, according to the Horton–Strahler classification system, for the entire Romanian territory. The results consist of a polygonal vector layer in shapefile format, containing an attribute table with all the initial, intermediary, and final calculations in separate numeric fields. Each parameter was normalized in order to obtain the final morphometric flood vulnerability score. Postprocessing these results involved applying a Principal Component Analysis to identify weights for the components that encompass all morphometric parameters. Each drainage basin reveals a dimensionless morphometric flood vulnerability score value that is comparable with all other basins in Romania.

“…A key component of natural risk management is spatial planning, which can predict an area's growth and set boundaries based on the possibility of a risk appearing [12]. In the context of the increasing trend of expansion of built space, studies are needed to avoid building on land vulnerable to risk processes [13,14]. Monitoring landslides is a necessary activity, given that Romania is one of the European countries with the most extensive areas with high and very high susceptibility [13].…”

“…The purpose of the studies is not only to avoid authorizing construction or infrastructure projects, but also to argue for the allocation of funds for land stabilization measures [12]. In addition, the estimation of potential financial losses due to landslides could help to increase awareness of the negative effects of these risk processes in the population and local governments [12,14].…”

“…Landslides have also been analyzed for various purposes concerning spatial planning issues: assessment of land vulnerability to risk processes in urban development [31], impact of land use change on landslide susceptibility [25], assessment of geo-hazards for increasing resilience at the local level [14], landslide management in the urban environment [32], and analysis of how landslides are integrated into spatial planning policies at the European level [13].…”

Spatial planning decisions form the basis of territorial progress by enhancing the resilience and opportunities for local and regional development. Therefore, decisions made as a result of multidisciplinary studies based on GIS assessment of all involved factors can provide a real and up-to-date image of the analyzed territory. In this context, geomorphic processes are among the factors restricting development, affecting built-up areas, transport infrastructure, and economic activities. This paper assesses geomorphic processes at the level of Cluj County, Romania, which mainly consist of active landslides that directly impact the accessibility of communities and their degree of safety, while accelerated soil erosion severely affects the output of land used for agriculture. GIS technology and a semi-quantitative model for determining the landslide hazard were used to classify landslides across occurrence probability classes. This methodology was implemented in Romania through Government Decision no. 447/2003. The USLE model was used to determine the soil erosion. As a result, the territory of Cluj County, which is the study area of this paper, was entirely included in one of the classes of risk concerning active geomorphic processes. Another important aspect consisted of categorizing transport infrastructure according to risk classes. A population risk assessment was also performed, taking into account the degree of accessibility of the territorial emergency department in the event that such hazards and processes occur. These results form the basis of proposals to efficiently plan the county territory, adapting decisions to the present trends in the evolution.
