I n t e r p r e t a t i o n :The paper presents the geomorphic attributes involved in a scenario for sustainable ecosystem management in several protected areas of Ignis-Gutai Mountains Romania.Geoforms are frequently used to substantiate decisions or to communicate impact assessment tools, due to their supporting role and to the readable features on maps. The present study used a multi-scale and layered approach, forged for the goals of the local stakeholders (including discussions with them and w i t h t h e s c i e n t i f i c community).Different types of scenarios, integrative and explorative versions, for the Local Action Group M a r a -G u t a i ( a n intercommunal privatepublic association that acts as a main funding b o d y f o r s m a l l development projects in the area) served to determine the relevance of geomorphic attributes involved in the sustainable ecosystem management scenario.M o r p h o g r a p h i c , m o r p h o m e t r i c a n d m o r p h o g e n e t i c approaches highlight the i m p o r t a n c e o f communicating these scenarios via a set of maps and graphs focusing on geoforms.
Downscaling and modeling natural disturbances such as the extratropical storms are important for understanding and predicting the behavior of the air flow over complex forested areas, especially in high wind instances that cause damages. Therefore, the rationale of the research was that the windscape of a storm could be reconstructed based on the features of consequent forest windthrows. Main input data for the model were derived from data on forest damages (extension, orientation, and depth of windthrows) retrieved from combined UAV imagery, high-resolution imagery, and field survey, integrated with terrain, wind data at stations within the study area, land cover, overturning and breaking point conditions for tree species, and human interventions. Using a GIS environment, a critical wind speed index was calculated, as well as the main wind direction on each damaged stand, considering the factors that lead to windthrows. This model was then compared to a computational fluid dynamics wind model built with WindNinja app, using the conservation of mass and momentum solver, at the moment of the storm, and adjusted. Ultimately, maps and 3D models were presented to the main stakeholders in the area, namely, forest management, protected area operatives, and road and tourist infrastructures’ management in order to enhance the resilience strategies and environmental protection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
