New software will be developed to include sediment sizing and concentration measurements. The added features have already been tested in IIHR in separate equipment settings and were found to work successfully. The proposed configuration for the PTV system will combine these features in one setting, creating a powerful nonintrusive tool for measurements in a complex flow environment (both field and laboratory conditions) where there are no alternative measurement techniques. The PTV system proposed herein is also applicable to experimental investigations in clear-water and multi-phase flows. Its submerged feature facilitates measurements near the free surface and near the bed.
