1. INTRODUCTIONA natural river adjusts its roughness, channel geometry, slope I length, and Pattern to changing hydrologic, geologic, and manmade conditions. However, some sort of mean condition or quasi-equilibriumcondition appears to exist for natural streams. The earliest attempts to describe the quasi--equlibrium geometry of rivers were the empirical approaches, such as the regime approach proposed by Lacey (1929) andLeoPOld et al. (1953 ). Later, theoretical approaches based on the… 相似文献
