Grubbing or clearing is the removal of trees, shrubs, stumps and rubbish from a site. This is often at the site where a transportation or utility corridor, a road or power line, an edifice or a garden is to be constructed. Grubbing is performed following clearance of trees to their stumps, preceding construction. [1]
Time-lapse of Tigercat mulcher clearing brush. Forestry mulching is a land clearing method that uses a single machine to cut, grind, and clear vegetation.. A forestry mulching machine, also referred to as a forestry mulcher, forest masticator, or brushcutter, uses a rotary drum equipped with steel chipper tools ("teeth") or blades to shred vegetation.

A hoe is an ancient and versatile agricultural and horticultural hand tool used to shape soil, remove weeds, clear soil, and harvest root crops. Shaping the soil includes piling soil around the base of plants ( hilling ), digging narrow furrows ( drills ) and shallow trenches for planting seeds or bulbs .
The Swedish Slip Circle method assumes that the friction angle of the soil or rock is equal to zero, i.e., = ′. In other words, when friction angle is considered to be zero, the effective stress term goes to zero, thus equating the shear strength to the cohesion parameter of the given soil.
The AASHTO Soil Classification System was developed by the American Association of State Highway and Transportation Officials, and is used as a guide for the classification of soils and soil-aggregate mixtures for highway construction purposes.
Conduct file searches with public agencies (State water board, fire department, county health department, etc.) having oversight relative to water quality and soil contamination issues. Examine historical aerial photography of the vicinity. Examine current USGS maps to scrutinize drainage patterns and topography.
In soil science, soil gradation is a classification of a coarse-grained soil that ranks the soil based on the different particle sizes contained in the soil. [1] Soil gradation is an important aspect of soil mechanics and geotechnical engineering because it is an indicator of other engineering properties such as compressibility , shear strength ...
The NRCS curve number is related to soil type, soil infiltration capability, land use, and the depth of the seasonal high water table. To account for different soils' ability to infiltrate, NRCS has divided soils into four hydrologic soil groups (HSGs). They are defined as follows. [1]
