1. Satellite Images High-resolution surface reflectance images, including the Landsat 5 TM, Landsat 7 ETM+, Landsat 8 OLI acquired from the Google Earth Engine (GEE, website), plus with HJ-1A/B (Huanjing) CCD, HJ-2A/B CCD and GF-1 (GaoFeng) WFV downloaded from the China Centre for Resources Satellite Data and Application (CRESDA, https://data.cresda.cn/) was used to study the spreading dynamics of the Yellow River turbid plume (YRP) (Table.1). 26 good-quality (i.e., cloud cover <10%, low tide level) scenes covering Yellow River estuary (YRE) with image acquisition data before and after the implementation of WSRS were selected for this study. 2. Runoff and sediment load data Long time series of daily runoff and sediment load data recorded at the Lijin Hydrological Station (http://www.yrcc.gov.cn/) (2003–2023), which is the closest station to the estuary to the YRE, were collected to show the variations in water discharge and sediment supply due to WSRS. To illustrate wind forcing and ocean currents effects on river plume, we use hourly sea surface wind at a 0.125°×0.125° grid resolution provided by the fifth-generation European center for medium-range weather forecast atmospheric reanalysis data of the global climate (ERA5), together with 3-hourly ocean surface currents derived from the global surface 1/12° product of Hybrid Coordinate Ocean Model (HYCOM). 3. Current and wind field data The ocean current field data is derived from the reanalysis data of the Hybrid Coordinate Ocean Model (HYCOM) of the US Navy (https://www.hycom.org/), with a spatial resolution of 1/12° × 1/12° and a vertical depth from the surface to 20 m.. The hourly wind speed and direction data for the Bohai Sea are sourced from the European Centre for Medium-Range Weather Forecasts (ECMWF) (https://cds.climate.copernicus.eu/), with a spatial resolution of 1/4° × 1/4°. The high accuracy of these data has been validated in the study area.
