Rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. The three major classes of rock are igneous, sedimentary, and metamorphic rock. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe rock types. Additionally, different classification systems exist for each major type of rock. There are different types of rocks existing in nature.

the guidelines presented apply equally to rock and rubble riprap. Guidelines for other types are presented in HEC-11. 7.9.2 Bank Slope A primary consideration in the design of stable riprap bank protection schemes is the slope of the channel bank. For riprap installations, normally the maximum recommended face slope is 1V:2H. 7.9.3 Rock Size Commonly used sizes for gravel include: Pea Gravel: Typically 1/4 inch to 1/2 inch (about 0.6 cm to 1.3 cm) in diameter. It is often used for landscaping and pathways. Crushed Stone #5: Ranging from 1 inch to 1.5 inches (about 2.5 cm to 3.8 cm) in diameter.
