Abstract

In the Mediterranean region, suspended sediment transport is the predominant process of material removaland sediment transport. The aim of this paper is to analyze the sediment dynamics and to compare differentcalculation methods in order to identify the most suitable for temporary rivers. At this purpose, continuousmeasurements of the flow and discrete values of sediment concentrations recorded from 2010 to 2011 havebeen used. Sampling was carried out with different frequencies as a function of the flow conditions. Severalcalculation methods were compared: Averaging Estimator Methods, Ratio Estimator Methods e RegressionEstimator Methods. The suspended sediment load was estimated in the range of 141-1123 tkm-2yr-1. Applyinga flow regime Stratification based on a flow exceeded frequency (f1<20%; 20%<f2<80%; f3>80%),the range of values was found in a restricted interval 298-595 tkm-2yr-1. Results show that the stratificationapproach is necessary methodology in load fluxes estimation in temporary rivers.
