On the eve of the discontinuation of Stevens chart recorders, we are republishing the following article about the highest profile contribution that our products have made in their 116 year history. This article was originally published in the Stevens Water Monitor newsletter in 2007. One of the longest lived products in water resource monitoring has […]

It has long been known that there is a strong relationship between soil water content and the health and yield of crops. But only in the past few decades has science quantified the specifics of these relationships. This research has expanded to develop a relationship between soil moisture levels and the impact on meteorological and

Stevens introduces two new digital sensors with a smart mix of unique features and an attractive price point. The first in a line-up of rugged digital sensors, they offer built-in processing of measured data, eliminating the need to perform complex calculations to process the data for many applications. Stevens’ Smart PT is a ceramic membrane
On April 20, 2017 we hosted the first in a series of soil physics training webinars. Here is the recording of the session as well as the slide deck we used. The webinar covered the following: Installation of soil sensors and things you should consider before going into the field. Best management practices and recommendations
Here are 7 questions and answers about using the Stevens HydraProbe. Q: What is the difference between the terms “real dielectric constant” (RDC) and the “real dielectric permittivity”? A: The terms real dielectric constant and real dielectric permittivity are often times used interchangeably and in a matter of speaking, are synonyms to one another. The

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

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.

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,

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
