yec provides a broad range of technical services that help its clients apply appropriate environmentally conscious actions to all phases of concept, planning, designing, constructing, servicing, and maintaining projects in fields such as roads, rivers, ports, and urban and regional planning.We have been actively involved in emerging environmental issues by leveraging our track record in the environment and our comprehensive technical capabilities through collaboration involving our technical experts across a broad range of fields.

Environment Building a More Beautiful Earth for Our ChildrenInteracting with the Earth and Disaster Prevention

Water is one of the most vital resources for human security. It is also home to diverse organisms, and it acts as a lifeline to stabilize the Earth’s climate. We have conducted predictive assessments of water risk by numerical simulations, examined the measures to be taken, and made water conservation plans through collaboration with residents so that we can constantly deliver safe water.

Traditional satoyama (rural landscapes) and satoumi (rural marine areas) have been built in such a way that people can maintain a balance with nature. However, the balance has begun to break down. We have helped build rich urban areas in which a variety of organisms exist and people connect mutually, based o n o u r a c h i e v e m e n t s i n r e a l i z i n g s a t o y a m a conservation plans, examining the conservation methods for rare species, and putt ing together information about preservation activities.

　 Contamination of soil and groundwater and leachate from waste disposal sites

Today, humankind has an issue regarding global climate change, and must therefore build a recycling-oriented society by implementing 3R policies and a low-carbon society by reducing greenhouse gases generated by waste disposal. In addition, in an age of economic challenges, waste disposal must be managed efficiently.With advanced technical support for the planning, designing, and other assistance in relation to waste, yec aims to help build a recycling-oriented society, prevent global warming, and construct a waste treatment system that increases business efficiency.yec will also try to eliminate the negative legacy related to the environment, for example, eliminating pollution caused by illegal dumping. In addition, we facilitate proper disposal and recycling of disaster waste, and the proper disposal of radioactive pollution and decontamination waste.

Approximately 70% of the land of Japan is mountainous. Sediment-related disasters such as debris flow and landslides are frequent. Our departments of Geological Conditions and Grounds have existed since our founding, and we have researched and analyzed large-scale construction, disaster prevention, sand erosion control, and subsurface environments. The departments have an excellent reputation for their expertise.

Geological Conditions and Grounds

In the 21st century, known as the century of water, we have increasingly focused on groundwater, also referred to as Blue Gold. As a general civil engineering consultant, yec has participated in conserving, reclaiming, and developing groundwater resources, taking advantage of its comprehensive technical skills in such fields as geology, groundwater, rivers, and the environment.

Dur ing the e ra o f h igh economic g rowth , in f ras t ruc tu re development projects were intended for new, large urban development and to create a good living environment. Today, we are entering an era of maintaining and updating our existing assets. We are now in a critical age when we need to promote business related to mass transfer that resulted from the Great East Japan Earthquake.yec has been working as an adviser for roads, land forming, and water and sewage design, and has quickly presented advanced technical proposals and know-how to customers in infrastructure development projects and transfer business.

Infrastructure Development Offering Safe and Secure Lifelines to Everyone

地下水解析（影響予測評価）事例

Mountain tunnels are an essential road structure in Japan, given that approximately two-thirds of the country is mountainous. In addition, more tunnels have recently been constructed in urban areas to overcome site and other constraints. Tunnels are constructions created inside the ground. Therefore, they are strongly influenced by the landforms, nature of the soil, groundwater, faults, and other factors, while they may cause ground subsidence and changes in the groundwater environment.When planning and designing a tunnel, in full consideration of the above issues, we focus on maintenance of the surrounding environment, safety at the time of construction, and stability after completion.

Flood control measures are the basics of building safe and secure rivers. yec has researched, planned, and designed tangible and intangible measures from its own unique perspectives. Among tangible measures, we have built dams, flood control basins, and pumping stations, and conducted river improvement work as measures to help prevent disasters from occurring. For intangible measures, we have worked on flood forecasting and flood information systems as disaster mitigation measures.yec has also committed itself to maintaining, repairing, and reinforcing river management facilities to continuously maintain their functions after construction, while we have worked on neo-natural river reconstruction and nature restoration to ensure the safety of flood control, and conserve and regenerate the natural environment.

Rivers River Development Leading to a Better Future Transmission of Dam Design Technologies that Support the Country

To help customers construct new dams and redevelop dams, yec has planned and designed dams and undertaken construction planning. In addition, we have conducted consultation activities on dams and peripheral structures by creating small hydro projects. These are driven by a small amount of water, which harnesses running water and uses the energy from dropping water, to build a system for maintaining and managing existing dams. This system verifies the seismic adequacy of dams in the case of a large-scale earthquake.

Ensuring continuity for the longitudinal profile of the river is vital for fish reproduction. When designing a Kubota groundsels, we generally determine the form based on hydraulic experiments, taking into account the impact on the fish swimming upstream and the habitat of swans.

In addition to creating and updating the maintenance management plan of the Arakawa River downstream office and the Yodogawa River office, we have

conducted river patrol support, forest management, sediment management, and life extension planning for the river structures.

In July 2004, heavy rain caused flood damage along the Kariyada and Igarashi Rivers. As restoration measures, we planned and designed the flood control basin development of the Kariyada River, dam improvement, river channel development, and river channel widening of the Igarashi River, and embankment maintenance.When heavy rain occurred again in July 2011, the restoration measures were able to suppress the occurrence of damage in the city section.

In the Ina River basin, where inland water damage occurs because of “guerri l la rainstorms,” we have established the Ina River Flood Messenger to share flooding information reported by the residents in the area on the Web by the use of mobile devices.

Ensuring flood control safety is important. On the other hand, the natural appearance of rivers can be ruined. For the regeneration of n a t u r e i n t h e O n g a R i v e r , Nakajima, we ran workshops on spawning a variety of flora and fauna, and restoring, planning, designing, and utilizing wetlands to ensure their survival.

We have conducted the model tests, analysis, manual preparation support, seismic performance verification of each office, and seismic design strengthening by help ing a customer prepare the guidel ines for comparing and verifying the seismic performance of river structures and associated illustrations.

As a measure in the downstream area of the Oyodo River, which was affected by typhoon No. 14 on September 17, 2005, we planned and designed the Uryuno river drainage pumping station and the disaster prevention ST, in order to mitigate the water damage.

Maintenance and Management Cycle

Seismic Performance VerificationCrack Generation Region

Dams in the management stage are evaluated through dam follow-ups and overall dam checks as well as administrative checks based on data that is accumulated daily. It is important that the maintenance and management of dams are repeatedly conducted in the cycle of monitoring → evaluation → determination → improvement. This enables the following:● Understand when dams need to be maintained or

updated● Give feedback for appropriate budgetary actions

and maintenance plans● Help improve the efficiency of inspection and

reduce the total cost by classifying some dam facilities as those for corrective maintenance so as to exclude them from the inspection items or reduce the inspection frequency.

● Maintain and manage dams in an economically effective way

Focusing on large-scale ground motions that are expected to occur, and based on ground motions that occurred in the past near dam sites, active faults, and plate boundaries, we conduct simulations that introduce motions to the linear dynamic analysis model that represents the dam body and the foundation rock. As a result, if damage is observed in the dam body, we analyze the progression of damage caused by the earthquake with a non-linear analysis to evaluate the stability of the dam body.

Small hydropower generation harnesses water drops, which can be seen everywhere. yec has leveraged not only existing dams but also erosion control dam facilities, the power of the flow of rivers, the drop in agricultural irrigation channels, and the pipes of water purification facilities. These technologies were then brought to our loca l -dr iven, d is t r ibuted energy development plans based on local production for local consumption.

Our customers for dam maintenance and management are:Ministry of Land, Infrastructure, Transport and Tourism (Tohoku, Chubu, and Hokuriku Regional Development Bureaus, IFIC), Iwate, Fukushima, Shimane, Niigata, Nagasaki, and Okinawa prefectures

Our customers for small hydropower projects are:Ministry of Land, Infrastructure, Transport and Tourism, Yamagata, Miyagi, Niigata, Kanagawa, Yamanashi, Nagano, Okayama, and Okinawa prefectures, Water Agency and New Energy Foundation in Germany, and so on.

The Kinosaki drainage pumping station is located in Kinosaki-cho, Toyooka, Hyogo Prefecture, and was built for the drainage system behind the levee of the Otani River.However, typhoon No. 23 made landfall in the Kinki region in 2004 and brought heavy rain to the Maruyama River basin, causing extensive damage.In response, MLIT developed a special emergency project to handle the situation and decided to increase the drainage capacity of the pump station from 15 ㎥/s to 23 ㎥/s. In addition to the facilities themselves, yec also helps with the maintenance and updating of drainage pumping stations.※Special emergency projects - Special emergency projects for the control of severe river disasters

Kinosaki Drainage Pumping Station

In Japan, more than 99% of food and fuel is imported and exported via ports; therefore, ports and airports need to be enhanced as the foundation that supports Japan's international competitiveness. In addition, coastal areas are places with large populations; so Japan has to be prepared for a massive earthquake that could occur in the Nankai Trough, by learning from the Great East Japan Earthquake that caused unprecedented damage. To realize the above, yec has provided the technology for planning, facil ity designing, and environmental assessment as a total coordinator.
