The hillslope-riparian-stream continuum (HRSC) may be significantly influenced by interbasin transfer of water. However, the integration processes of transferred water into HRSC and the hydrological and hydrochemical responses of HRSC remain poorly understood. Based on the hydrological observation and hydrogeochemical analyses, we delineate the processes and influences of Yellow River water integration into the HRSC of the Fen River, clarifying the essential mechanisms. Our results indicate that high mixing ratios of transferred water in the channel (94%) and increased recharge into the aquifer are responsible for noticeable hydraulic and hydrochemical influences within the HRSC. Specifically, the hydraulic impact range of the seepage river on adjacent groundwater is much greater than the range of hydrochemical influence. The mixing of river water and groundwater is confined to the riparian zone. Approximately 14% of Na⁺ and K⁺ ions were adsorbed from the percolating river water through ion exchange prior to mixing. During the intervals of the transfer, bank storage backflow persisted for an average of about four weeks, imposing hydrochemical influences on the Fen River similar to those of the transferred water. Additionally, we found that the repelling salts effect of icing induces an overestimation of the proportion of the end member with higher ion concentrations. Our study highlights the importance of anthropogenic water cycle processes on earth system.

山坡-河岸-河流连续体（HRSC）可能会受到流域间水输送的显着影响。然而，人们对转移水进入 HRSC 的整合过程以及 HRSC 的水文和水化学反应仍然知之甚少。基于水文观测和水文地球化学分析，勾画了黄河水流入汾河余热的过程和影响，明确了其基本机制。我们的结果表明，渠道中转移水的高混合比（94％）和含水层补给的增加是对 HRSC 内显着的水力和水化学影响的原因。具体而言，渗流河对邻近地下水的水力影响范围远大于水化学影响范围。河水与地下水的混合仅限于河岸带。混合前通过离子交换从渗滤河水中吸附了约 14% 的 Na ⁺和 K ⁺离子。调水期间，岸库回流平均持续约4周，对汾河造成与调水类似的水化学影响。此外，我们发现结冰的排斥盐效应会导致高估离子浓度较高的端元比例。我们的研究强调了人为水循环过程对地球系统的重要性。
