ABSTRACT
During the 1920s to 1940s, Bojonegoro was often hit by floods, which had an impact on its people. Floods were detrimental to the socioeconomic sector of the Bojonegoro community. In writing about the flood events in Bojonegoro from 1920 to 1940, the author uses historical research methods that have several stages, such as heuristics and interpretation. Bojonegoro is an area close to the Bengawan Solo River. The Bojonegoro area is prone to flooding caused by rainfall, which causes the overflow of water from the Bengawan Solo River to the Bojonegoro community settlements. The flood had an impact on the activities of the residents of Bojonegoro, as in 1931 the flood disrupted the road traffic and caused congestion. In addition, in 1933 the flood caused the temporary shutdown of Bumiputra women's school. Actions were taken during the Dutch colonial period by repairing and building dams in Bojonegoro; this has been done since the enactment of the era of ethical politics.
