There can be a build-up of salt [7] in a wicking bed. They must be flushed from time to time. Well-constructed beds with a good drain typically get flushed or diluted in heavy rain, which is not usually an issue. However, in a long-term drought, it is important to flush through the water occasionally.
In geology, a graded bed is a bed characterized by a systematic change in grain or clast size from bottom to top of the bed. Most commonly this takes the form of normal grading , with coarser sediments at the base, which grade upward into progressively finer ones.
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 ...
These beds range from millimeters to centimeters thick and can even go to meters or multiple meters thick. Sedimentary structures such as cross-bedding , graded bedding , and ripple marks are utilized in stratigraphic studies to indicate original position of strata in geologically complex terrains and understand the depositional environment of ...

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.
Researchers attribute a rise in autism diagnoses to increased screening and changing definitions of the condition. Hundreds of studies have found childhood vaccines to be safe.
