The Study of Relationship between Climatic Elements (Precipitation and Temperature) with Runoff in the Navroud Basin

摘要

There are many factors that can affect the amount oudf runoff in an area. Some of these factors are related to basin features such as physiographic features of basin, gudeology, vegetation, soil conditions, etc and some other factors with intervention of human activities in the natural environment, causing increased runoff and createudirreversible losses in the region. This article used descriptive and experimental methods, to examine the relationship between climatic elements (precipitation and temperature) with runoff in the Navroud basin. In this study, the correlation between altitude and rainfall , beudtween temperature and runoff also between snowudfall and runoff was found negative. On the other hand, the correlation between rainfall and runoff got positive. Therefore, the role of climatic elements such as temperudature, rainfall and snowfall in the basin is quite tangible
