Impact of Changjiang-Hanjiang Water Diversion Project on the runoff process in the lower reach of Hanjiang River.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Inter-basin water transfer is a commonly adopted measure for improving hydrological and ecological conditions within watersheds. However, systematically quantifying the actual improvement effects of water diversion projects on watershed runoff conditions remains a weak link in current hydraulic engineering evaluation. This study conducts complex modeling of the Changjiang-Hanjiang Water Diversion Project (CHWD), the Middle Route of South-to-North Water Diversion Project (MR-SNWD), the Dongjing River diversion, and the cascade reservoirs in the middle and lower reaches of the Hanjiang River with Soil and Water Assessment Tool (SWAT). Based on this modeling framework, the daily runoff process is simulated in the lower Hanjiang River under a scenario with no CHWD, and the impact of the CHWD on the runoff process is investigated in the lower Hanjiang River. The results indicate that: (1) the water supplementation from the CHWD is insufficient to balance the reduction impact on downstream Hanjiang River runoff caused by water withdrawal from the MR-SNWD; (2) the water supplementation from the CHWD is primarily utilized to supply the Dongjing River diversion, with limited effect on increasing runoff in the Hanjiang River section downstream of Dongjing River; (3) the water supplementation from the CHWD contributes to enhancing the stability of the runoff process in the lower Hanjiang River. This study yields a significant insight that gravity-flow water conveyance is suboptimal for inter-basin water transfer in flat terrain regions. These findings offer valuable implications for the planning and design of such projects globally.
