为了弄清城市集水区的径流机制，本文报道了对城市集水区径流的现场观测和径流分析的应用。在过去的几十年里，城市化使城市地区的土地利用变得更加复杂。城市化使城市河流洪峰流量增大，洪水集中时间缩短。此外，日本的大量人口和财产都集中在洪水泛滥的平原上，洪水泛滥的可能性很大。这使得城市洪涝灾害问题更加严重。然而，日本城市集水区的流量数据非常少。本文通过实地径流观测，应用基于地貌和地质特征的地表径流分析方法，评价了城市化对城市径流的影响。
In order to clarify the runoff mechanism in urban catchments area, field observation of discharge and application of runoff analysis to the urban catchments are reported in this paper. Land-use in urban area has become more complicated by urbanization during the last several decades. As a result of urbanization, the peak discharge of flood increases and the concentration time of flood decreases in urban rivers. In addition, large amount of the population and property are concentrated in floodplains which have the large potential of inundation in Japan. It makes flood disasters in urban area more serious problem. However, discharge data in urban catchments in Japan are very few. In this paper, field observation of discharge are carried out and runoff analysis method for land surface area based on morphological and geological properties is applied several urban catchments to evaluate the effects of urbanization on runoff in urban area.
