Data from: Multi-year deployment of a Single Frequency High-Frequency acoustic attenuation system for measuring fine suspended sediments in stream channels

This is the dataset that was used to make the figures for the publication entitled "Multi-year deployment of a Single Frequency High-Frequency acoustic attenuation system for measuring fine suspended sediments in stream channels."How the dataset was generated: A single frequency acoustic attention system was deployed for over three years in the Goodwin Creek Experimental Watershed in Panola County, MS, USA, to measure suspended fine sediments (dWhy the dataset was generated: This dataset presents an opportunity for employees at the USDA-ARS-National Sedimentation Laboratory (NSL) to utilize the single frequency acoustic attention system in order to enhance the array of measurements conducted within the Goodwin Creek Experimental Watershed. Continuous collection of sediment transport measurements is often unfeasible; therefore, sediment rating curves are employed to correlate a limited set of physical samples with ongoing measurements of stream discharge. Although this method is generally more precise than relying solely on sediment transport models, the relationships occurring among seasonal variations in watersheds, channel dynamics, and precipitation can lead to significant discrepancies between rating curves and actual transport rates. Furthermore, the data obtained from the Single Frequency Acoustic Attenuation System (SFAAS) may indicate clockwise hysteresis relationships between fine sediment transport and stream flow, aligning with anticipated patterns identified in prior studies. Additionally, the SFAAS has uncovered two distinct transport regimes that are not explained by temporal or seasonal climate variations, thereby opening avenues for future research focused on enhancing the hydrological understanding of how spatial rainfall heterogeneity influences sediment transport within the watershed.
