Seasonal dynamics of water quality in response to land use changes in the Chi and Mun River Basins Thailand.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The Chi and Mun River Basins, the primary tributary of the Mekong River Basin in Thailand, is undergoing significant land use changes that impact water quality. Understanding the relationship between land use and water quality is crucial for effective river basin management, providing insights applicable to global water systems. While past studies have examined water quality in the Mekong River Basin, research specifically focusing on the Chi-Mun River Basin remains limited. This study analyzes the spatial and temporal effects of land use changes on water quality from 2007 to 2021 using land use change estimation, 11 water quality parameters, and redundancy analysis (RDA). Water samples were collected in January, March, May, and August across multiple years. Seasonal variations were assessed, with dry season samples from January and March and wet season samples from May and August. Key findings include: (1) pH, Biochemical Oxygen Demand, Total Coliform Bacteria, Fecal Coliform Bacteria, Total Phosphorus, Nitrate Nitrogen, Ammonia-Nitrogen, and Suspended Solids increased during the wet season, while (2) Dissolved Oxygen, Electrical Conductivity, and Water Quality Index were higher in the dry season. (3) Land use changes had a greater impact on water quality during the wet season, driven by increased runoff from expanding urban and agricultural areas and declining paddy and forest cover. (4) Forests and aquatic areas improved water quality, while agricultural and urban expansion contributed to its deterioration. These findings underscore the need for sustainable land management strategies to balance regional development with ecological conservation in the Chi-Mun River Basin.
