概述了支持设计和实施与自然相结合的现实和战略性河流保护和恢复计划的三个地貌考虑因素。首先，讨论了认识河流形式和过程的固有多样性的重要性。其次，评估河流动态，构建与系统演化相关的河段当代行为状况，以解释河流特征和行为随时间的变化。第三，河段的轨迹与河流类型的下游模式相关，分析流域尺度的景观连通性，以解释河流地貌恢复潜力。通过对澳大利亚东南部贝加和上亨特流域的人类干扰地貌河流响应进行广泛的流域规模分析，证明了这些原理的应用。对范围和流域规模的恢复规划的不同影响促使管理实践必须与自然合作，而不是努力“对抗现场”。
Three geomorphic considerations that underpin the design and implementation of realistic and strategic river conservation and rehabilitation programs that work with the nature are outlined. First, the importance of appreciating the inherent diversity of river forms and processes is discussed. Second, river dynamics are appraised, framing the contemporary behavioral regime of a reach in relation to system evolution to explain changes to river character and behavior over time. Third, the trajectory of a reach is framed in relation to downstream patterns of river types, analyzing landscape connectivity at the catchment scale to interpret geomorphic river recovery potential. The application of these principles is demonstrated using extensive catchment-scale analyses of geomorphic river responses to human disturbance in the Bega and Upper Hunter catchments in southeastern Australia. Differing implications for reach- and catchment-scale rehabilitation planning prompt the imperative that management practices work with nature rather than strive to 'fight the site.'.
