Hydrological Survey
We provide consistent technology for groundwater surveys of various construction projects (Dams, tunnels, river improvement works), from field survey, and measurement to simulation, and analysis.
Hydrological survey
Develop a survey plan based on basic groundwater information obtained from field surveys (Source survey, hydrological utilization survey, etc.)
Site measurement
Monitor field groundwater information (Flow rate, water level, pumping amount, water quality, depth of water loss, etc.)
Fow measurement (Container method)
Flow measurement (Cross section method)
Flow measurement(Salt dilution method)
Water level measurement
Analysis
Groundwater flow analysis using tank models and 3D simulations (MODEFLOW2000, etc.) based on on-site groundwater information
Work analysis
