在人类对河道的各种形式的干扰中，清除河岸植被和清除木质残体也许是最普遍的。这些影响的地貌后果在不同的河流系统之间有着明显的差异，这是集水环境、气候、地质、沉积物供应和演化历史变化的结果。在本文中，河流的地貌反应，快速，系统的清除河岸植被在新世界（殖民地）社会的变化进行了对比与逐渐的，零碎的，但渐进的清除河岸森林在北方欧洲（旧世界）。据推测，戏剧性的性质，河流变形经历的景观，如澳大利亚东南部的记录，以不同的方式在旧世界的景观经历的基本地貌阈值的突破。
Clearance of riparian vegetation and removal of woody debris are perhaps the most pervasive of all forms of human disturbance to river courses. Geomorphic consequences of these impacts have varied markedly from river system to river system, a result of variations in catchment setting, climate, geology, sediment supply and evolutionary history. In this paper, geomorphic responses of rivers to rapid, systematic clearance of riparian vegetation in New World (colonial) societies are contrasted with changes associated with gradual, piecemeal, yet progressive clearance of riparian forests in northern Europe (the Old World). It is postulated that the dramatic nature of river metamorphosis experienced in landscapes such as southeastern Australia records the breaching of fundamental geomorphic thresholds in a different manner to that experienced in Old World landscapes.
