TL;DR: Using land use types and landscape metrics, as well as statistical and spatial analysis, Wang et al. as mentioned in this paper determined the relationships between land use patterns and river water quality in the Taizi River basin, China, during dry and rainy seasons in 2009.

TL;DR: Most forms of nitrogen were interrelated with physicochemical parameters during different seasons, displaying nitrification and denitrification processes that occurred in the river rather than seasonal biological demand.

TL;DR: In this article, the in-stream nitrate and its isotopic composition (δ15N-NO3 and δ18O- NO3) were analyzed to explore the seasonal nitrate sources and its transformation processes combining with chemical indicators in the Haicheng River during the spring, early summer, late summer, and autumn seasons throughout the year of 2010.

TL;DR: Investigation of land-use patterns on nitrogen pollution in the Haicheng River basin in Northeast China during 2010 suggested that regulating built-up land uses and reducing discharges of domestic sewage and industrial wastewater would be effective methods for river nitrogen control.

TL;DR: In this paper, a method for river classification based on water quality assessment (WQA) was introduced using factor analysis (FA) in the Taizi River basin, where sixty-nine sampling sites and 20 water quality parameters were selected for monitoring and analysis, denoted as general, hardness, trophic, nitrogen pollution, and physical factors.
