Integrated River Basin Management Planning and Design: Case Study of a River Course

The certain river is currently facing a critical water quality crisis, severely degraded by the combined effects of internal sediment pollution and external discharges from industrial and domestic sources. This has led to a significant loss of its self-purification capacity and a damaged aquatic ecosystem. To address these issues, this study proposes a comprehensive management strategy based on a dual approach of "pollution reduction" and "capacity enhancement." The core of this strategy involves a four-pronged action plan: controlling external pollution inputs, removing internal contaminants through sediment cleanup, restoring the riverine ecosystem, and improving water circulation and quality. This plan is integrated with governmental administrative measures to create a holistic management framework from source to sink. The implementation of this design is projected to substantially reduce the river's pollution load, significantly improve its water quality, and restore its natural self-purification capabilities. Ultimately, this will promote the ecological recovery of the river. This study aims to provide a practical and replicable model for the integrated management of similarly impaired water bodies worldwide.
