Abstract
The dataset contains timeseries of turbidity, suspended sediment concentration, water level and discharge data collected from Potash Brook (16.4 Km²), an urban watershed in South Burlington, Vermont to investigate the influence of urbanization on suspended sediment transport dynamics. Turbidity data were collected from June 2024 to July 2025 at a frequency of 10 minutes using in-situ Cyclops-7 turbidimeter designed by Turner Designs and integrated with a Cyclops-7 logger by Precision Measurement Engineering, Inc. Turbidity was then related to suspended sediment concentration (SSC) through a power regression built using 158 discrete samples. SSC was determined using a modified US EPA method 160.2, from 200 mL storm events samples collected with an automatic ISCO 6712C compact sampler. Water level data were collected using MX2001-S pressure transducer (Onset, HOBO). A stage-discharge rating curve was developed using six discharge measurements obtained with a FlowTracker2 handheld acoustic Doppler velocimeter (SonTek) and Marsh-McBirney flow meter. The data were collected at Station 6, the most downstream site on Potash Brook (44°26'47.9"N 73°12'13.3"W), and is part of a distributed sensor network.
