Abstract:
Correlation and multiple linear regression were analyzed to modulate structural equations in order to evaluate, in 14 dispersed stations, the amounts of salts brought by Righ canal (southeastern Algeria) to the Chott Merouane during winter (October 16th to April 15th) and summer (April 16th to October 15th) seasons of 2012. In fact, these periods allowed determining the annual mean of these amounts by measuring electrical conductivity and streamflow (obtained using the gauging method by the exploration of the velocity field). Results showed that winter streamflow provided measuring range from 178 l/s to 5450 l/s. Values obtained in summer were comprised between 90 l/s and 2560 l/s while the annual means spread between 134 l/s and 3967 1/s. Winter, summer and annual electrical conductivities showed respective values of 15.02 to 17.71 mS/cm, 16 to 21.21 mS/cm and 15.51 to 19.46 mS/cm. From the statistical analysis, two regressive equations were built in each period of study that allowed assessing amounts of salts. However, model 2 fit better to data than Model 1. Therefore, the suggested method was found as a highly useful approach that simulates reality in predicting the amounts of salts and could be relevant on waterways of identical hydro-agricultural areas.
