“…The sensor probe used is capable of measuring turbidity from 0 to 3,000 NTU, a range acceptable for turbidity measurements in the streams of Madeira island-except in the case of extreme hydrological events, since turbidity measurements above 3,000 NTU correspond to sediment loads so high that they make it difficult to indirectly quantify the SSC by the adopted method-which has also been demonstrated to be suitable in other studies of suspended sediments (see, e.g., [20,30,31]).…”

The aim of this study was to assess the applicability of indirect techniques for streamflow and suspended sediment concentration estimation and their use in the calculation of suspended sediment transport rate in the small mountain watersheds of Madeira Island, Portugal. Emphasis was given to the application of salt dilution gauging to the indirect determination of the flow rate and the use of water turbidity data to estimate the concentration of suspended sediments. The field and laboratory work carried out are briefly described, and the main experimental results and the field data from the short measurement campaign performed in the Ribeira Seca stream in Faial, on the north side of the island, are presented and discussed. Whilst the measurement campaign carried out was temporally and spatially limited, it was pioneering for Madeira and allowed to verify the applicability of the indirect hydrometric and sedimentometric techniques used in this exploratory study.
