径流与潮差对钦江河口盐水入侵距离的影响机制
Mechanisms of the runoff and tidal impacting on the distance of saltwater intrusion in the Qinjiang River Estuary
摘要
Abstract
In this paper,a three-dimensional mathematical model was constructed to quantitatively analyze the saltwater intrusion distance in the Qinjiang River Estuary under different combinations of runoff and tidal range.The results show that the change in saltwater intrusion distance was inversely proportional to the change in river runoff and positively proportional to the change in tidal range.Specifically,under conditions of minimal tidal range,a linear correlation is observed between the saltwater intrusion distance and river discharge.Conversely,as the tidal range intensifies,the relationship becomes increasingly nonlinear,conforming to a power function(y=axn).Furthermore,this investigation has yielded a predictive equation for saltwater intrusion distance,derived from nonlinear multiple regression analysis,which has been substantiated through rigorous validation.This formula is poised to aid in the optimization of local water resource allocation and management strategies.关键词
