Permitting Non-Tidal Beaches
Beach Sand Replenishment Replenishment of beach sand may be allowed, but in general, must not exceed more than 10 cubic yards of sand and must not occur more frequently than once every six years. Permit applications for beach sand replenishment should incorporate methods for diversion of surface runoff around the beach area.

Beach Nourishment (U.S. National Park Service)
Beach nourishment is the process of placing additional sediment on a beach or in the nearshore. A wider and higher beach can provide storm protection for coastal structures, create new habitat, and enhance the beach for recreation. Sediment is commonly dredged offshore and pumped directly onto the beach or dumped nearshore by a hopper dredge ...

Sand winning threatens coastal tourism in Central Region
Consequently, pronounced coastal erosion had washed away some buildings. Coconut trees are seen dented and slanted as a direct effect of the sand winning activities. It is evidently clear that the rate of replenishment of sand from the sea is less than the rate of extraction. The difference manifested itself in the rapid coastal erosion.

Rainfall is the only source of soil water replenishment and the limiting factor for vegetation cover in desert ecosystems (Wang et al. 2007). Infiltration rates and soil water distribution are significantly influenced by vegetation characteristics, soil texture, and soil physical properties (Wang et al. 2007; Itzhak et al. 2008).
