| Abstract: | Objective]The aim was to study the sediment situation of Zuncun Yellow River diversion irrigated area channel.Method]The water flow sediment-carrying capacity and influence factors of Zuncun Yellow River diversion irrigated area channel were analyzed.Result] The water flow sediment-carrying capacity of Zuncun Yellow River diversion irrigated area channel at summer irrigation stage was larger than that at spring irrigation stage,and the change trend of water flow sediment-carrying capacity of observation section at different irrigation stages was basically unanimous.The main factors affecting sediment-carrying capacity of Zuncun Yellow River diversion irrigated area channel were flow, sediment concentration, etc..Conclusion]The result provides reference for alleviating channel siltation problem. |
