[HGM02-01] Geomorphology in relation to engineering and GIS: A historical review
★Invited Papers
キーワード：地形、工学、GIS、レビュー
Geomorphology is a scientific discipline for the study of landforms. Although it has been developed mainly as pure science, it is also relevant to applied science such as engineering. For example, studies on soil and rock mechanics in civil engineering and engineering geology have provided useful information for understanding hillslope processes and resultant landforms. Relevant concepts such as "rock control in Geomorphology" have attracted attention since the mid 20th century. Another aspect that relates Geomorphology to engineering is the application of GIS (Geographical Information Systems). GIS became a major tool in Geomorphology in the mid-1990s, especially in the field of Geomorphometry. The early GIS propagation in Japan around 1990 was promoted mainly by researchers in engineering. Later researchers in Geography and Geoscience including geomorphologists started using GIS, and they depended on previous technological development by engineers. Even today, technologies provided by engineers often contribute to Geomorphology, like the creation of digital elevation models from remote sensing data. Conversely, scientific findings by geomorphologists are useful for civil engineering activities on land surfaces. This presentation reviews relationships among Geomoprholgy, engineering, and GIS, and then discusses their implications and significance. The contents are related to the international symposium of the Japanese Geomorphological Union with a relevant theme to be held in late 2022.
