Abstract Sediment budget is a valuable tool for describing the sediment production, transfer and storage in a watershed and its components depend on different watershed physical properties. The present study aimed to evaluate the relationship between 22 geomorphological factors and sediment budget components in a small mountainous watershed in the west of Iran, using ordinary least square, geographically weighted regression and bivariate regression. The distribution map of erosion and deposition was prepared using 137Cs in 15 sub-watersheds and the internal area. According to the results, the maximum net erosion rates were related with the sub-watersheds with medium slope (

流域地貌特征对沉积物再分布的影响

摘要 泥沙预算是描述流域泥沙产生、转移和储存的重要工具，其组成部分取决于不同流域的物理性质。本研究旨在使用普通最小二乘法、地理加权回归和双变量回归评估伊朗西部一个小型山区流域中 22 个地貌因素与沉积物收支分量之间的关系。利用15个子流域和内部区域的137Cs绘制了侵蚀和沉积的分布图。结果表明，最大净侵蚀速率与中等坡度的子流域（
