Ground-Water Flow Beneath Levee 35A from Conservation Area 2B, Broward County, Florida.

摘要

Conservation Area 28 is an area of recharge for the surficial aquifer system in Broward County. Water stored in the conservation area provides the hydraulic potential for downward flow to the high permeability zone of the Biscayne aquifer. A 5.64 foot head differential (average for the period of record) between water levels in conservation Area 2B and water levels in the adjacent levee 35A borrow canal causes water to leak into the canal at an average rate of about 2.2 times ten to the minus 9 cubic feet per second per lineal foot of canal and accounts for a loss of 0.013 foot per day of surface water from conservation Area 2B. Amounts of canal leakage and underflow are constantly changing and are dependent upon the head differential between Conservation Area 2B and levee 35A borrow canal.
