Soil Moisture Applications and Practices Using the HydraProbe Soil Moisture Sensor

Over the past ten years, environmental monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related soil hydrological processes. …

Stevens HydraProbe Helps in Landslide Research

Each year during the wet season we hear news reports about landslides in America and abroad. Sometimes these events happen in unpopulated areas but unfortunately they also occur in areas where people live, causing property damage and taking lives. But what causes these events and what can be done about them? That’s what Dr. Burns, …

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 …

The Role of Soil Moisture on our Climate, Weather and Global Warming

Global warming is a topic that has received much attention in the media, especially during the hot days of summer. The process by which carbon dioxide (CO2) in the atmosphere prevents the escape of thermal energy into outer space is known as the greenhouse effect. The higher the carbon dioxide levels in the atmosphere the …

Soil Geomorphology and Identification

When working with or studying the soil, it’s important to know what type of soil is being examined. Each type of soil has different characteristics, and will have different effects on water infiltration rates, water holding capacity, evapotranspiration rate, and other soil characteristics. Soil sensors are one popular way of measuring soil moisture, salinity, temperature …
