Abstract

One aim of this study was to assess the efficiency of 3 mathematical models (a rational, an exponential, and a simplified Gaussian function) for the calculation of the mass transport, as compared to the linear spline interpolation. Another aim was to compare the mass transport calculated from field measurements obtained from a minimum of 3 discrete sampling heights with measurements of 9 sampling heights. With this purpose, wind erosion was measured under low surface roughness conditions on an Entic Haplustoll, located at an experimental site of Santa Rosa (La Pampa), during 25 events. Results showed that under similar field conditions, mass transport amounts can differ more than 45% if calculated using different sampling heights or mathematical models
