Abstract: Yangtze River Basin is grappling with a critical issue of soil erosion, with over 500,000 square kilometres still experiencing water and soil loss. Annually, this erosion leads to the degradation and desertification of nearly a million acres of arable land. Jialing River, as the largest tributary in the upper reaches of the Yangtze River system, has soil erosion problems that represent one of the key challenges in the Basin’s management. Streamflow and sediment load within the basin are pivotal factors influencing soil erosion and ecosystem stability. By leveraging streamflow and sediment load data from the hydrological control stations at the outlets of the Jialing River Basin, we performed a predictive analysis for the upcoming 15 years of water and sediment dynamics in the basin. Furthermore, we constructed a novel hydrological model to elucidate these forecasted results, which showed good predictive performance. This methodology not only offers data and theoretical backing for the governance of water and sediment in the Jialing River Basin but is also applicable to other basins.
