Soil Moisture & Evapotranspiration

Home > Business Focus > Soil Moisture & Evapotranspiration

We conduct hydrological survey which consists of various measurements; streamflow involving the IRDIMS (Integrated Real-time DIscharge Measurement System), sediment load, soil moisture, and evapotranspiration throughout the all country.

※ Precipitation and water level are measured by MOLIT and groundwater is measured by K-water.

Soil Moisture & Evapotranspiration

Soil moisture is measured by TDR (Time Domain Reflectometry) using the changes of characteristics of dielectric constant.

Evapotranspiration is calculated by eddy covariance method using a energy conservation equation measuring the wind fluxes of turbulences and the concentration of vapour.
