In order to solve problems such as watershed flood control to cope with severe and frequent flood damage caused by abnormal weather and the aging of river structures, and to meet the needs for environmental protection and friendly water use, we conduct various surveys, plans, and designs in rivers, dams, and erosion control.
In rivers, we conduct post-flood trace water level surveys and damage coverage surveys, and analyze the causes of damage and the mechanisms. In erosion control, we observe the amount of quicksand, analyze sediment dynamics, and research methods for predicting and monitoring sediment disasters.
We plan and design embankments that take advantage of the desirable river environment and scenery, and we plan and design natural regeneration projects that restore the rich habitat and growth environment and historical river structures.
At dams, we inspect civil engineering structures, gate equipment, telecommunications facilities, etc., and formulate service life extension plans. In rivers, we inspect embankments and revetments, flumes and downpipes, and evaluate facilities and develop monitoring plans.
We support a planning of Kawamachi (river & town) development project, and Mizubering initiative, which aims to create waterfront attractions and revitalize the region by organically linking the river and town development.
We investigate the causes of water quality problems such as blue-green algae, freshwater red tide, mold odor, and turbid water that occur in dams, lakes, and marshes, analyze the occurrence mechanisms, and study methods to control or improve the occurrence of these problems.
