· Results indied that gravel had promoted or reduced effects on infiltration capacity which could affect further the cumulative runoff volume and cumulative sediment mass increase or decrease. The cumulative infiltration volume in 25 % proportion of gravel was less than those in 0,, and 50 % proportion of gravel.
Gravel diaphragms are simply gravel filled trenches which act as inlet structures by redistributing concentrated flow to sheet flow: reducing the erosive power of the water and promoting also act as a pretreatment by settling out sediment particles before they reach any downstream structure or practice.. If the contributing drainage area is solely turf .
· Stones will not change the characteristics of the pores in soil and so they won't change the capillary action of soil. Once you understand how water moves through the soil, and the effect of these two forces, you quickly see that rocks at the bottom of the pot can't reduce the saturation zone, so they don't increase drainage.
In gravelrich streams, effects downstream of mining sites may be shortlived when mining ends, because the balance between sediment input and transport at a site can reestablish itself relatively quickly. Effects in gravelpoor streams may develop rapidly and persist for many years after mining has finished.
Natural aggregate (crushed stone, sand, and gravel) is a vital part of our economic infrastructure in Minnesota. Aggregate is used for road and bridge construction and in a variety of building materials. In 2003, the value of construction sand and gravel and crushed stone .

They are the most ancient (stones, bricks, glasses), usually made by previous calcination of raw materials (making cement powder) and final curing of composite mixtures, concrete is made with cement, sand and gravel (plus water). They are resistant to wear (but not to impact), lighter than metals, insulating, porous and fragile
· Rock type influence on permeability. Permeability values of rocks range over many factors of 10; therefore, permeability is plotted on a logarithmic scale. Values commonly encountered in petroleum reservoirs range from a fraction of a millidarcy to several darcies.
