Storm-event suspended sediment, nutrient dynamics, autocorrelation, and hysteresis patterns in the Binan River Basin

This dataset contains high-frequency hydrological and water quality measurements associated with storm events in the Binan River Basin, China. It includes:Time series data distinguishing high suspended sediment events and low- or no-sediment events.Autocorrelation coefficients of suspended sediment concentrations and associated hysteresis behavior.Seasonal variations in nutrient indicators (total nitrogen, total phosphorus, CODMn and ammonia nitrogen) under different hysteresis conditions.Event-scale hysteresis indices characterizing pollutant–sediment relationships across storm events.The dataset supports analysis of sediment-driven nutrient transport, hysteresis dynamics under varying hydrological conditions, and seasonal patterns of water quality in mountainous watersheds.
