“…The SCS-CN method proved to be an efficient tool for estimating direct runoff in such a small mountainous watershed, as also shown by other studies that applied the method to various watersheds in Romania such as the ones conducted by , Strapazan & Petruț, 2017, Gyori et al, 2016, Ivanescu et al, 2014, Gyori & Haidu, 2011, and Crăciun et al, 2007 calibration based on the SCS lag time formula, yielded results that were in poor agreement with the measured values. The lag equation tended to underestimate the relationship between the corresponding travel time and the rainfall parameters, and hence the peak flow was overestimated, which is why the manual adjustment of the lag time was needed.…”

“…Generally, most digital computer models for calculating surface runoff apply to predefined calculation sections and drainage areas (Haidu et al, 2017), thus the catchment boundary and most of the parameters necessary for MIKE-UHM model's operation were extracted using both the GIS-ArcHydro model based on a previous work by Strapazan & Petruț (2017), and the HEC-GeoHMS module.…”

Hydrologic modelling studies usually involve data series with a large temporal scale, especially in Romania, focusing on a long-term impact analysis. Nevertheless, event-based runoff models are essential tools for short-term purposes such as flash flood forecasting. Suitable methods or models must be considered in order to ensure the validity of such research based on parameter calibration to a particular area. Therefore, a comparative analysis of methods must be conducted first, in order to determine the optimal ones that can be used for future data prediction. The aim of the present study is to apply and validate the MIKE HYDRO River modeling system - the UHM module, through a comparative analysis of the SCS, Generalized SCS and Proportional Loss methods available, to a small-sized mountainous watershed, where no research has been conducted in this field. To this end, three spring rainfall events were chosen, but with different antecedent moisture conditions, in order to examine how well the chosen methods can reproduce the available observations in such circumstances. The SCS method yielded the highest quality performance, but the Proportional Loss method has also proven effective under these conditions.

“…The digital elevation model for Europe (EU-DEM) with a resolution of 25 m from the GMES RDA project (a realisation of the Copernicus programme, managed by the European Commission, DG Enterprise and Industry) from the website of the European Environment Agency (EU-DEM Metadata) was used to subtract information on relief. In order to automatically delineate the watersheds a model based on the elevation data and ArcHydro functions was used (Strapazan and Petruț, 2017).…”

There is an increasing need to assess and quantify the impact of land use/land cover changes, especially on surface runoff, due to rapid population growth. This study aims to investigate the land use/land cover (LULC) changes over time, for an intense rainfall event in Țibleș, Runc and Sălăuța watersheds, and their impacts on surface runoff for various antecedent moisture conditions (AMC). The GIS-based SCS-CN method and the CORINE land cover (CLC) databases for 2000, 2006 and 2012 laid the foundation for this research. Results indicated that even small land cover changes can significantly affect runoff on the short time scale, with quantitatively different effects regarding moisture conditions. The reduction in forest cover due to agricultural intensification and the conversion from pasture to cropland (especially between 2000 and 2006) resulted in higher surface runoff volumes. These changes mostly affected the middle and downstream catchments of the main rivers which means that over the years, the soil water retaining capacity has decreased.

“…HEC-GeoHMS has been elaborated as a toolkit that enables the stakeholders to perform spatial analysis by developing hydrologic parameters. This software is a widely used extension of Geographic Information Systems (GIS) [19][20][21][22]. The output hydrologic parameters generated by HEC-GeoHMS constitute the input data for the rainfall-runoff simulation model.…”

Forest operations engineering deals with all the essential infrastructure operations aiming at the efficient management of forested areas, which constitutes a prerequisite for the development of mountainous economies. Thus, the need for addressing this objective in an effective way, in conjunction with other issues associated with the protection and preservation of forest wealth, is of utmost importance. There are a whole range of forest operations for which a decision-making web-tool can potentially be utilized. This paper introduces an online decision-making tool for managing forest roads, which uses information derived from rainfall-runoff simulation. The proposed tool can be used to provide information about forest works maintenance and damage prevention in a forest environment. Furthermore, the tool assists in visualizing forest operations and achieves the optimization of their management. The development of the decision-making tool is also described, and a real case study (the Koupa watershed) is presented in detail to demonstrate its application and resulting advantages. The rainfall-runoff simulation was conducted for ten sub-basins in order to evaluate the efficiency of the corresponding culverts in the Koupa watershed.
