摘要

Part 1describes investigations designed to evaluate interpretations of detailed soil maps,as a means of determining flood plain boundaries for regulatory purposes. Part 2describes similar studies based on interpretation of airphotos. Six Wisconsin sites were studied. Boundaries of 100year floods determined by engineering methods were used as a basis of comparison. Results showed that reasonably accurate boundaries of 100year floods can be drawn in many places by interpretation of detailed soil maps. Results of airphoto studies showed that flood plain boundaries could also be drawn by interpretation of aerial photographs,in areas where physiographic features were distinct.
