Abstract: The topographic characteristics of a basin have great influence on runoff processes. If a lumped runoff model that takes into account the topographic characteristics of a basin can simulate runoff processes as exactly as and faster than a distributed runoff model, the former will be very useful. This paper describes a method to lump and scale up a distributed runoff model taking into account the topographic characteristics and shows the results of its application. In our method, we investigate distributed nature of topographic characteristics in a basin using the Basin Geomorphic Information System (BGIS), and lump slope systems using the cluster analysis technique. We also make a lumped stream network model on the assumption that stream discharge varies linearly along each stream segment at individual moment.
