have been determined from an analysis of the least square support vector machine (LS SVM) and Fuzzy C-mean system (FCM). Finding the best data input combinations using Gamma Test (GT) was done. It was very clear from model identification in GT that four...

length and degree of slope have been measured. Surface area of rills has been calculated by measuring width and depth of each rill and their geometric sections. Gamma test has been applied in order to find optimal combination of input parameters. Whereas...

, including canopy cover, ground cover, gravel, sand, silt, clay, slope and its common effect on length have been measured. By measuring, widths and depth of any rill and their geometric section, surface area of rills have been calculated. Gamma test has been...

mathematical techniques are available for use, basic concerns remain unsolved such as simplicity, high accuracy, real time use in many stations of a region, and the low availability of inputs. In this study, a nonlinear modeling with Gamma Test (GT) has been...

the likely input combinations. In addition, there is no guidance about how many data points should be used in the calibration and what

accuracy the best model is able to achieve. In this study, the Gamma test has been used for the first time as a...
