Aproject is to be built on a moderately sloping site immediately below the mouth of a canyon near phoenix, arizona. using the geologic terms described in section 2.6 of your textbook, what type of soil is most likely to be found? why? what engineering characteristics would you expect from these soils? explain.

The location - he mouth of a canyon near phoenix, Arizona is in an arid area, and the moderate slope. So the site is probably on an alluvial fan. The soils should be coarser near the mouth of the canyon and become finer away from the mouth. The soils may be layered with interbedded sediments including gravels, sands, silts and clays.

plants will die and decay, causing a decrease in dissolved oxygen; plants will block sunlight to deeper water.
