Building drainage channels and floodways

Incorporating “urban greening” such as wetlands and environmental buffers

Creating flood warning systems

Steel Slit dam

Preserve a Natural ecosystem “through the Mountain to the Sea”

Normal timeCapturing mudflow and

driftwood

In normal time: passing harmless sand and water from the mountains to the lower stream

In a time of disaster: capturing mudflow and driftwood, and protecting human life

7

Project example in Philippines

Type : Slit type A

Location : Anilao river upper stream, Ormoc, Leyte island

Construction period : 1998 to 2001

Purpose: Flood disaster prevention(driftwood, debris flow)

Captured driftwood and sediment

Project site

Project example in Taiwan

Type : Slit type B and its modified ver.

Location :中興大学惠蓀林場内蘭島渓

Highlights: Effectively captured debrisflow & driftwood in 2013

Project example

1 year after construction,

the site was perfectly covered with vegetation

CONSTRUCTION EXAMPLE IN TAIWAN

Gabion box is made of welded steel mesh, used as retaining walls, river bank conservation, etc.

Easy to install

(in case of retaining wall)

GABION BOX

Right after construction 4 months later

Not only stones, soil are available as filler, so we can greening outside of the box

Community-based Flood Monitoring System

Overview of the flood monitoring system

This flood monitoring system enables you to observe remote

locations and detect signs of flood. It is helpful for early warning.

Internet Cloudmonitoring stations

Flood monitoring web service

Advantages are;Able to deploy anywhere at minimum cost,

time and maintenance.- Driven by solar power and sending data

through mobile phone network.

- Consisted by commodity parts and it can be

procured in local market.

Optional sensors are available.

Provide through the Internet as a cloud

service. - Initial investment is saved.

- Get the information anywhere and anytime

as long as the internet access is available.

Advantages of the system

Solar panel

Camera &

communication
