Engineering use which involves beneficially using dredged sediment as an alternative to land based resources (e.g., quarry aggregate or soil replacement) and is common to many engineering projects, e.g. land reclamation, beach nourishment and coastal protection works.

The authors started with the impact of mining or quarrying raw material on soil fauna and of the manufacture of cement, concrete, and ceramics.
In a range of confining pressure of 30 600 kPa, the strength and stiffness of well-compacted CCA is similar to, or, in some cases even higher than, typical selected high-class backfill materials (e.g., well-graded gravelly soil of crushed quarry hard rock).
The folk motifs of the first movement, marked Allegro barbaro, are quarried from the same Russian soil as those used by Stravinsky in "The Rite of Spring" and are propelled by similar irregular rhythms.
Since mushroom hunting means bushwhacking off trail while constantly looking down for the quarry — a subtle bulge in the soil marks a matsutake's nascent push to the surface — disorientation can occur pretty fast.

But he was also quarrying deeper into his own national soil and reaching back beyond the 19th-century dead end of Charles Stamford, Hubert Parry and their complacent oratorios.
It is an agricultural mining region (pesticides, phosphate, zinc, lead, marble quarry, gravel quarries) whose both air and soil pollutants are to be considered as risk factors in future asthma related etiologic studies.
In the present work, successional plant and soil dynamics on abandoned gypsum quarries were studied, using the chronosequences approach covering a time span of 70 years.
