• Facility Design

Rainfall in mountainous areas can sometimes erode riverbeds, mountain slopes, and riverbanks, resulting in debris flows that rush down. To prevent damage to towns, roads, and agricultural land caused by such debris flows and floating logs, sediment control dams are established to protect livelihoods. Depending on the characteristics of the watershed, multiple sediment control dams may be installed, along with measures against floating logs, landslide countermeasures, and slope protection, to capture the amount of sediment runoff. 【Main Business Achievements】 ■ Ministry of Land, Infrastructure, Transport and Tourism, Tohoku Regional Development Bureau, Shinjo River Office ■ Ministry of Land, Infrastructure, Transport and Tourism, Hokuriku Regional Development Bureau, Iide Mountain System Sediment Control Office ■ Ministry of Land, Infrastructure, Transport and Tourism, Kanto Regional Development Bureau, Fujikawa Sediment Control Office ■ Saitama Prefecture, Hannō Prefectural Land Development Office ■ Niigata Prefecture, Nagaoka Regional Promotion Bureau *For more details, please refer to the PDF document or feel free to contact us.

• Facility Design

The main role of the drainage pumping station is to forcibly discharge the water accumulated in the tributaries into the main river to protect the lives and livelihoods of people in the surrounding areas from flooding in the main river. When the main river rises, the water can backflow into the levee side, causing flooding damage. Even if the sluice gates are closed to prevent external water from flowing in, flooding damage cannot be avoided due to the inability to drain internal water. Therefore, it becomes possible to discharge the water accumulated in the tributaries to the main river side, thereby reducing flooding damage on the tributary side. 【Internal Water Analysis and Drainage Pumping Station Design Process】 ■ Rainfall Analysis ■ Internal Water Analysis ■ Design of the Drainage Pumping Station *For more details, please refer to the PDF materials or feel free to contact us.

• Facility Design

We would like to introduce a case where we conducted verification of the improvement effects of flood damage through pump installation. In the current runoff simulation analysis, we reproduced the flooding situation based on actual rainfall using the existing facilities. Flooding areas were identified that were almost the same as past flooding history, and the validity of the analysis parameters was confirmed. In the runoff simulation analysis after the measures were implemented, the improvement effects of the pump station installation were confirmed. [Case Study] ■ Current runoff simulation analysis - Many manholes are flooded with water levels higher than the ground surface. ■ Runoff simulation analysis after measures - Flooded manholes were eliminated, and flood damage was resolved. *For more details, please refer to the PDF document or feel free to contact us.

• Site and ground investigation

In "permeation flow analysis," it is important to accurately reflect the water level behavior within the embankment. To understand the water level conditions within the embankment, we participated in a joint research project involving the Public Works Research Institute (at that time), the National Institute for Land and Infrastructure Management (at that time), and eight private companies, titled "Development of Water Level Observation Methods within Embankments for Advanced Embankment Management Technology." From the various water level observation methods used in the joint research, we were able to obtain generally valid water level observation results within the embankment, and the outcomes were compiled into a "Manual (Draft) for Water Level Observation within River Embankments."
