### IntErO Implementation on the Three Selected Prototype River Basins in Cluj County  
The results following the IntErO model implementation in the three river basins from Cluj County are presented in the following tables: Table 1, which constitutes the input data, Tables 2-4, which present the values of the factors used in the intensity of erosion and outflow for each of the river basins, and Table 5, which represents the IntErO report with the result outputs. The Y, Xa and \(\varphi\) coefficients presented in Tables 2-4 display the soil cover, soil resistance and type/extent of erosion in each of the three river basins. The coefficient of soil cover (protection) is denoted by the letter X, and it is a dimensionless quantity that is determined by the catchment's land use, as well as the vegetative cover. The value of this coefficient might range anywhere from 0.05 to 1. A low level of soil protection is indicated by values near to 0, while a high level of soil protection is indicated by values close to 1. Y is the coefficient of soil erodibility, which reflects the resistance of soils to erosion. It is dependent on the pedological and lithological properties of the watershed. The values of this dimensionless factor can be obtained either by studies in a laboratory or from measurements taken in the field, and the range typically extends from 0.25 to 2. Formations with values close to 2 are considered to have a high erodibility, whilst those with values close to 0.25 have a low erodibility. When conducting this research, the Y factor was determined by analyzing the data from the soil map, as well as the geological map of the study area. Following that, coefficient values were allotted to the various types of soil based on the EPM recommendations as well as the results of earlier studies [1; 5; 9; 38; 39]. \(\varphi\) is a coefficient that changes, depending on the amount of active erosion, as well as the degree to which linear erosion extends and the magnitude of mass movements. It is a factor that has no dimensions, and its values can vary from 0.1 to 1. According to the principles outlined in the EPM technique, a value of \(\varphi\) has been assigned to each distinct category of erosion form [40; 41]. The data presented in Table 5 presents the calculation result of the IntErO model implementation for the three river watersheds. The coefficients of the river basin form (A), was calculated as 0.58 for Batin, 0.45 for Rasca, and 0.52 for Chinteni. The coefficient of the watershed development (m) had the values of 0.39, 0.72, 0.63, and the average river basin width (B) had the values of 3.21, 1.87, 2.54 km for the three river basins. The asymmetry coefficients (a) of the river basins were calculated as 0.02, 0.93 and 0.08, which indicates the possibility of large flood waves coming in the future for the Rasca watershed, which had a high value. The drainage density of the study river basin (G)--a key aspect affecting the flood hydrogen and erosion process is the drainage density--was calculated as 1.03, 1.08 and 0.45, which indicates that there is a medium density of the hydrographic network in the three watersheds. Maximum outflow from the river basin (Qmax) was estimated to be 26.22, 67.58 and 33.47 m\({}^{3}\) s\({}^{-1}\), highlighting the greater value for the mountainous Rasca river basin. According to IntErO report, the Z coefficient for Batin and Rasca was 0.227 and 0.211, which indicates that both river basins belong to the fourth destruction category (out of five), highlighting that the strength of the erosion process is weak, and, according to the erosion type, it is surface erosion. The Z coefficient for the Chinteni watershed, estimated as 0.434, indicates that the river basin belongs to the third destruction category. The strength of the erosion process is high, and, according to the erosion type, it is mixed erosion [1; 9].
