Title: Integrating drought warning water level with analytical hedging for reservoir water supply operation (under review)Draft authors: Wenhua Wan, Zongzhi Wang, Liang Cheng, Ying Bai, Wenqi Wang, and Kun Wang<br>Attached files include:1. The long-term operation process of the Danjiangkou Reservoir optimized using the HR-based DP algorithm. Note: The inflow data has been omitted due to confidentiality regulations regarding streamflow observations.2. R codes for the HR-based DP algorithm, the processes deriving seasonal DWWL, and the statistical performance of HR with DWWL during typical drought years.3.R codes for synthetic streamflow and MCI sequence generation.
