Document Summary
The nominal diameter of a particle is the longest distance that nominally passes through the particle. The measure of the symmetry of a grain size distribution is termed. A sandstone that contains 45% matrix is generally termed a. The first bedforms to develop just as an oscillatory current can begin to move the bed material are termed. Sediment that goes into transport in suspension, only when a river is in flood, is termed the. Porosity and permeability both increase as the grain size of the material increases. Wave-formed ripples with ripple spacing that is much larger than the diameter of the wave orbital are termed. The form of cross-stratification shown in the following figure is termed. The process by which high speed fluid is swept towards a boundary and low speed fluid is ejected away from the boundary is termed . The upper flow regime is characterized by bedforms that are in phase with the water surface.
