The AA. applied the new hysteresis index to 3 suspended-sediment and discharge datasets from a small tropical rainforest catchment, the Lutzito catchment located on Barro Colorado Island, Panama. The datasets comprised a different number of events and sampling sites. Even few data may permit the identification of the dominating hysteresis pattern. It is highlighted that data covering a whole hydrological year permit analyzing trends in hysteresis. Data from 2 sites permit analyzing changes of hysteresis along the flowpath. The latter analysis supports the identification of suspended-sediment source areas. Furthermore, these results may serve as a first guideline on what to expect from an analysis of hysteresis patterns for datasets of varying quality and quantity
