Improved Water Supply Forecasts Using Soil Moisture Data

HydraProbe used to improve water supply forecast from 3 SNOTEL sites in Idaho over traditional antecedent conditions using the principle component forecast model Much of the water in the Western United States used for irrigation, municipal supplies and hydro-electric production originates as winter snow pack at higher elevations. Since the early 1900s, the correlation between […]

HydraProbe Field Portable Used to Validate the Soil Moisture Active Passive Satellite Data in Manitoba

The calibration and validation of remotely sensed soil moisture products relies upon an accurate source of ground truth data. The primary method of providing this ground truth is to conduct intensive field campaigns with manual surface soil moisture sampling measurements, which utilize gravimetric sampling, soil moisture probes, or both, to estimate the volumetric soil water

OSU Researchers Deploy Stevens Equipment in Study of Green Infrastructure Treatment for Groundwater Runoff

Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. In older city infrastructure, runoff from roofs, parking lots, and streets flows directly into the sewer system and must be handled by the municipal wastewater treatment facility, increasing the amount of work the system must undertake. For the past 30

Calibration of a Capacitance Soil Sensor Required to Achieve the Level of Accuracy Required for Satellite Ground Truthing

This study published in American Meteorological Society’s BAMS journal demonstrates the extent of variability in readings one can expect with a soil moisture sensor based on capacitance technology. To obtain the highest level of accuracy that is required for remote sensing applications, capacitance-based soil sensors often need to be recalibrated. The HydraProbe is an impedance-based

HydraProbe selected to be used in Canada’s RISMA Network for Agricultural Monitoring

A new study published in the Soil Science Society of America Journal investigated the field performance of 5 soil moisture instruments in heavy clay soils. The HydraProbe outperformed TDR and capacitance-based soil sensors in terms of stability and accuracy in Manitoba’s agricultural soil. Much of soil in the Canadian Prairie farmland is vertisolic. A new
