Multi-beam bathymetric survey for sediment confirmation in dams and reservoirs and understanding storage capacity.
In-house owned multi-beam depth sounder (suitable for inland waters)
Understanding the sedimentation status of dam lakes and reservoirs in a spatial manner! Acquiring three-dimensional terrain data that can be used for maintenance management and capacity evaluation.
In dams and reservoirs, understanding the progression of sedimentation and changes in topography is an important issue for long-term maintenance management and ensuring water storage capacity. Conventional single-line surveys may not adequately capture localized sedimentation conditions or subtle changes in topography. Our company utilizes our own multi-beam sonar equipment to accurately acquire the underwater topography of dam lakes and reservoirs in a comprehensive manner. 【Main Issues We Can Address】 - Confirmation of sedimentation conditions in dam lakes and reservoirs - Acquisition of topographic data for understanding water storage capacity - Preparation of foundational materials for maintenance management planning - Assessment of current conditions for dredging considerations - Analysis of topographic changes through year-on-year comparisons The acquired data can be organized into three-dimensional topographic models or contour maps. We will propose analyses tailored to the objectives of the management personnel.

Company information
Since its establishment in 1966, East Japan Construction Consultant has been proposing "aha!" moments centered around surveying and design technology for many years. Starting with surveying and expanding into design, land acquisition, compensation, and infrastructure maintenance, we have worked as a comprehensive construction consultant to enhance our services. We have been engaged in the development and maintenance of social infrastructure that supports people's safety, security, and economic activities, including roads, rivers, ports, marine surveys, urban planning, and energy. Currently, in addition to our efforts in disaster prevention, mitigation, and national resilience, we are also focusing on digital transformation (DX) through initiatives such as BIM/CIM, AI, UAVs, and ROVs (underwater drones).
