Tag: types of soil

In terms of soil texture, soil type usually refers to the different sizes of mineral particles in a particular sample. Soil is made up in part of finely ground rock particles, grouped according to size as sand and silt in addition to clay, organic material such as decomposed plant matter.

Soil Water Sensors

SOIL MOISTURE MONITORING CAN be useful as an irrigation management tool for both landscapes and agriculture, sometimes replacing an evapotranspiration-based (ET) approach or as a useful check on ET-based approaches since the latter tend to drift off target over time. All moisture sensors, also known as soil water sensors, measure

Measuring Earthwork Volumes

Formulas and methods for determining the volumes and areas of regular shapes and surfaces go back at least as far as ancient Greece. Pythagoras and other mathematicians determined the formulas that are still used to calculate the volumes of spheres and pyramids, as well as the areas of curve conic

Slide Rail Rules!

Often touted as the most flexible shoring system available, the slide-rail system is a vertical sheeting and trench support system that allows an excavation to be safely and economically shored from ground level to subgrade without any soil movement. Arguably, the slide-rail system has become the preferred shoring method for

How to Select a Soil Roller

Contractors use a number of different types of soil and aggregate compactors these days. Common types include: sheepsfoot rollers, which run static and are typically towed; pneumatic-tired rollers, which use rubber tires to provide the familiar kneading action of

The Worst-Case Scenario: Landfill Cover Erosion and Slope Instability

In March 1996 outside of Cincinnati, OH, the worst landslide in solid waste industry history occurred, resulting in a mass movement of more than 1 million cubic yards, a distance greater than 300 yards. Similarly, disastrous slides have occurred around the world: Hiriya, Israel, in the winter of 1997; the

Tools for Trenching in OSHA’s Soil Types

When trenching and using shoring, Mitch Post, Mabey Inc.’s training and development manager says that soil type only matters to a point. “One common mistake contractors make is placing too much emphasis on that soil typing. If you look strictly at the OSHA definition of what types of soil and

Making Rain Gardens Work

By Margaret Buranen Time is the test that reveals how well a rain garden is working. Time tells whether the rain garden’s design and construction are as effective as they were projected to be. Portland, OR, has a number of rain gardens that meet the test of time, including the
