By the late 19th century, Osaka's Yodo river underwent significant modernisation to improve navigation for steamships and reduce soil erosion — led by George Arnold Escher and Johannis de Rijke. The duo identified large amounts of sand delivered by affluent rivers as the primary reason for sediment buildup, which led them to propose solutions including an anti-erosion dam, reforestation and logging restrictions. Their plan also included constructing a 44-kilometre canal between Osaka and Kyoto, with a shallow water channel to ensure navigability during droughts. Riverbanks were reinforced with fascine mattresses to manage sediment and enhance flood control.

Civil engineering has shaped urban form and planning in Japan for centuries.
For long, the country has been threatened by natural hazards such as flooding,
typhoons, earthquakes and tsunamis — with engineering traditionally
providing the necessary defences.

During the Meiji era, the Japanese government invited Dutch hydraulic engineers
('watermannen') to help improve water infrastructure. Their innovative solutions
exemplified international collaboration during Japan's critical modernisation
period and underscores the enduring bond between both nations.

Initiated by Field Records, Waterworks covers over 50 Dutch waterworks developed
across Japan during the Meiji era. Navigate around the map and click on sites' names
to learn about their development — often accompanied by visual or sonic impressions.
