Burton LUP - 7Eb River Alluvium Without Overbank Deposits

7Eb River Alluvium Without Overbank Deposits

This hydrogeologic setting is characterized by flat-lying topography along the floodplains of some moderate-sized streams. Moderately thick, relatively coarse alluvium is found within these streams. Theses valleys lack significant fine-grained overbank deposits. Recharge is relatively high and the depth to water is less than 15 feet. The coarse alluvium (sand and gravel) aquifer is commonly in direct hydrologic contact with the surface stream. The alluvium may also serve as a source of recharge to the underlying, fractured, sedimentary rocks.
