Analysis of the Relationship between River Flow and Water Quality before and after the Wenchuan Earthquake

Abstract:

“5.12 Wenchuan earthquake”triggered floods, landslide, collapse and secondary geological disaster, trigger a new soil and water loss, having the significant influence to the local river water quality.This article through the statistical analysis of jiangyou, beichuan station 2006 ~ 2011 water conditions material, discussing the before and after the earthquake disaster areas the river flow change on the influence of river water quality. The results showed that the affected areas of ammonia nitrogen content after the earthquake are more than that before the earthquake content .with flow increased, ammonia nitrogen concentration is higher, flow is low, the water quality parameters of concentration decreased; The total hardness reduced during the earthquake, with flow increased, total hardness concentration is reduced, is negatively correlated; The change of flow to fluoride content effect is not obvious.
