Deposits
Deposition in a wadi is rapid because of the sudden loss of stream velocity and seepage of water into the porous sediment. Wadi deposits are thus usually poorly sorted gravels and sands. These sediments are often reworked by eolian processes.
Over time, wadi deposits may become "Inverted Wadis" where the presence at one time of underground water caused vegetation and sediment to fill in the Wadi's eroded channel to the point that previous washes appear as ridges running through desert regions.

Famous quotes containing the word deposits:
“Were all the worshippers of the gold calf to memorialize me and request a restoration of the deposits I would cut my right hand from my body before I would do such an act. The gold calf may be worshipped by others but as for myself I serve the Lord.”
—Andrew Jackson (1767–1845)
