摘要

This research attempts to explore the landform patterns apparent in the debris flow zones of the historic 2013 Colorado floods,by using“feng-shui”as a clue.In“feng-shui”,Chinese geomancy,the form school provides landform criteria used to select the favorable sites and to avoid risk areas.Debris flows involve the combined factors of landforms,climate,vegetation,soil,and postfire erosions.Colorado high-impact zones often experience a fire before the debris flow.Homes destroyed in high impact zones illustrate the failure of site selection and the lack of knowledge of debris flow,which reflects the weakness of education in environmental design.Education of survival knowledge and skills for designers and residents is crucial to develop a safe community.This research found significant agreement between“feng-shui”principles and geomorphic concepts in identifying landform patterns of debris flow zones.These patterns can be described in three areas:(a)the debris and runoff catchment;(b)the flow track that generates the speed and power of the debris flow as it proceeds downstream;and(c)the flow fan,the receiving area of the debris flow.In particular,dry washes and straight alignments,which“feng-shui”calls the“hidden arrow,”play a significant role in generating debris flows.This cross-cultural research could benefit site selection processes,planning efforts,and mitigation strategies to avoid building in risk areas and aid in natural disaster evacuation in the Colorado Rocky Mountains and beyond.
