Erosion Control

Japan's terrain is about 70% mountains. What's more, between heavy rain, earthquakes and volcanoes, the environment is perfect for landslide disasters. So to better help protect the lives and property of local residents, we offer a rich line of services to create safe living spaces that offer peace of mind.

Surveying/Planning
We carry out surveys to identify causes of landslides, such as amounts and conditions of loose earth and fallen timber, through aerial photography and on-site investigation.
Also, to protect human lives from landslides, we can draft evacuation warning projects based on past relationships between rainfall and landslides, with periods of at least 10 years up to 50 years after establishment.

Calculating Rainfall Safety Levels

Setting a level of rainfall as a condition for evacuation based on historical relationships between rain and landslides to reduce harm from landslide disasters.

Project Plan

Drafting long term (up to 50 years after establishment) or short term (approximately 10 years) projects based on comprehensive consideration of landslide damage estimates.

Facility design
To prevent landslides and ensure long-term safety, we can carry out planning for building new facilities or reinforcing existing ones based on the conditions and needs of the area.

Erosion Control Dam

To prevent landslides, we can carry out plans after examining current facilities and their locations, and considering the state of the area and answering local needs.

Planning Facilities to Protect Scenery

We carry out plans with an eye toward preserving natural landscapes, as well as installing erosion control that won’t harm fish habitation or prevent up- or downstream migration.

Operations & Management
After examining the current state of existing structures, we can draft O&M plans. We can also establish post-disaster recovery plans.

Reinforcement Planning

We can implement plans to ensure the long term strength and stability of existing erosion control facilities which may be deteriorating or in need of improvement after determining the causes of decay.
