Field Data Collection Report, Saugus River and Tributaries Flood Damage ReductionProject, Lynn, Malden, Revere, and Saugus, Massachusetts

摘要

The Saugus River system is located along the Atlantic Ocean coast approximately10 miles north of Boston, Massachusetts, near the cities of Lynn, Malden, and Revere, plus the town of Saugus. The Saugus River and its tributaries, including the Pines Rivers, comprise a 47-mile-square watershed area which drains into a tidal estuary at the mouth of the river. These estuaries and the adjacent salt-water marshes total approximately 1660 acres. The flows from the Saugus and Pines Rivers are relatively small, because of the sluggish characteristics of the watershed and the channel conveyance limits. They are also dependent on the tide. Storm-water drainage is temporarily stored in many areas in surface ponding when the tide is high followed by drainage when the tide is falling. The purpose of the Saugus River field monitoring program described herein was to collect synoptic data on water-level elevations, current velocity and directions, and suspended sediment and salinity concentrations at various stations throughout the system for use in hydrodynamic modelling of the area. The purpose of this report is to provide a permanent record of the instrumentation and techniques employed during the data collection survey and to make the data available for use in long-term numerical modeling and physical modeling studies for design of the floodgate, for assuring the natural tide levels and flushing patterns in the estuary, and for maintaining safe passage of local navigation.
