It is important to build in an air gap in a wicking bed, between the water and the soil, with only 5-10% of the area crossing that boundary for wicking. This stops the soil from getting too sodden and helps prevent an odorous anaerobic decomposition from occurring. A badly constructed wicking bed may even have organic matter in the reservoir ...
Cross-beds, or "sets," are not layered horizontally and are formed by a combination of local deposition on the inclined surfaces of ripples or dunes, and local erosion. Graded beds show a gradual change in grain or clast sizes from one side of the bed to the other. A normal grading occurs where there are larger grain sizes on the older side ...
Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH). Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.

The Bouma sequence is divided into 5 distinct layers labelled A through E, with A being at the bottom and E being at the top. Each layer described by Bouma has a specific set of sedimentary structures and a specific lithology (see below), with the layers overall getting finer-grained from bottom to top.

A streambed or stream bed is the bottom of a stream or river and is confined within a channel, or the banks of the waterway. [1] Usually, the bed does not contain terrestrial (land) vegetation and instead supports different types of aquatic vegetation ( aquatic plant ), depending on the type of streambed material and water velocity.
