The vertical hard basin drop structure, also called a dissipation wall, is the basic type of drop structure.The vertical hard basin drop consists of a vertical cutoff wall, usually built of concrete, that is usually laid perpendicular to the stream flow, and an impact basin, not unlike a stream pool, to catch the discharged water.
Wing walls can be classified according to their position in plan with respect to banks and abutments. The classification is as follows: Straight wing walls: used for small bridges, on drains with low banks and for railway bridges in cities (weep holes are provided).
Headward erosion creates three major kinds of drainage patterns: dendritic patterns, trellis patterns, and rectangular and angular patterns. Dendritic patterns form in homogenous landforms where the underlying bedrock has no structural control over where the water flows.
