東日本建設コンサルタント List of Products and Services

In waterway infrastructure such as ports, fishing ports, and dams, regular topographical surveys are required for long-term maintenance management. Localized sedimentation and erosion conditions that cannot be captured by conventional single-line surveys can be visualized in a planar manner through multi-beam sonar. Our company utilizes its own multi-beam sonar equipment to acquire three-dimensional data of the seabed topography. We conduct analyses that can be used for maintenance management tasks, such as comparing changes over time and estimating sediment volumes. 【Main Services Offered】 - Confirmation of changes over time through regular depth surveys - Monitoring of sedimentation progress - Acquisition of current topography for dredging plan considerations - Preparation of foundational data for maintenance management planning - Verification of seabed topography around structures We propose the development of data that serves as decision-making material for maintenance management, going beyond mere surveying.

In the maintenance and management of ports, fishing ports, and coastal areas along the Tohoku coast, the acquisition of extensive and high-precision seabed topography data is required. Our company conducts marine survey operations primarily along the Tohoku coast and is capable of area-wide depth measurement using our own multi-beam echo sounder. 【Available Areas】 - Tohoku coast (focusing on the coastal area of Fukushima Prefecture) - Southern Tohoku to the coastal area of northern Kanto 【Main Services Offered】 - Depth surveys of port areas - Confirmation of sedimentation conditions within fishing ports - Seabed topography surveys of coastal areas - Verification of seabed changes after disasters - Preparation of basic data for maintenance and management planning We will propose survey plans taking into account the marine conditions and regional characteristics of the Tohoku area.

In fishing ports, the progression of sediment accumulation within the harbor and the assurance of usable water depth are important issues for daily operations and maintenance management. Especially in small-scale ports, localized sediment accumulation and changes in topography can directly impact operations. Our company utilizes its own multi-beam sonar equipment to acquire the seabed topography within fishing ports in a comprehensive manner. This data can be visualized and analyzed as three-dimensional topographic data. 【Main Issues We Can Address】 - Confirmation of sediment accumulation status within the fishing port - Understanding of usable water depth - Acquisition of current topography for dredging range considerations - Confirmation of sediment progression through comparative analysis of changes over time - Creation of basic materials for maintenance management planning We have a track record of fishing port-related work, particularly along the Tohoku coast, and we propose survey plans that take regional characteristics into account.

In harbor depth and shallow surveys and maintenance management operations, it is essential to accurately understand the seabed topography around the quay and navigation routes. In traditional surveys using single measurement lines, there are cases where local sedimentation and scouring conditions cannot be sufficiently grasped. Our company utilizes its own multi-beam echo sounder to acquire seabed topography in the harbor area in a planar manner. This data can be visualized and analyzed as three-dimensional data. 【Main Issues We Can Address】 - Regular depth and shallow surveys in harbor areas - Confirmation of seabed topography around quays and revetments - Understanding sedimentation conditions and preparing dredging study materials - Confirmation of current topography in navigation routes - Acquisition of basic data for developing maintenance management plans Focusing on the Tohoku coastal area, we have a track record in harbor-related operations and can provide consistent support from investigation to analysis and mapping.

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.

In maintaining and managing harbors and fishing ports, as well as understanding sedimentation conditions and confirming changes in seabed topography, there are cases where the conventional single-line depth surveys cannot adequately capture the irregularities and localized changes. Our company conducts marine surveys utilizing our own multi-beam sonar equipment to acquire and analyze seabed topography with high precision over large areas. 【Main Issues We Can Address】 - Depth surveys of harbors and fishing ports - Understanding sedimentation conditions and considering dredging plans - Confirming seabed topography around aging facilities - Investigating seabed changes after disasters - Creating foundational data for maintenance and management plans We have a long history of engaging in marine surveys and harbor-related operations, particularly along the coast of Fukushima Prefecture, and we can provide comprehensive support from survey planning to measurement, data analysis, and mapping. We welcome inquiries from harbor and fishing port managers, design offices, construction companies, and anyone in need of seabed topography data.
