Water flow measurements quantify freshwater discharge under a section of the Tamiami Trail in southwest Florida. The U.S. Geological Survey collected data from 2006 or 2007 through September 2010 to establish a baseline for evaluating restoration projects. The study instrumented seven bridges and made periodic measurements at 51 total structures to estimate continuous daily mean discharge.
Use Cases
- Model relationships between discharge at instrumented bridges and stage to estimate flow at uninstrumented structures.
- Analyze the seasonal distribution of daily mean discharge values across the seven subbasins from 2008-2010.
- Assess spatial flow distribution by calculating percentage contributions from areas west and east of the Faka Union Canal.
- Evaluate restoration project effectiveness by comparing pre- and post-construction flow data for the 35 bridges and 16 culverts.
Strengths
- Continuous daily mean discharge estimates for 51 structures over approximately 4 years.
- Study design divided the area into seven instrumented subbasins for cost-effective, representative monitoring.
Limitations
- Subbasin comparison is limited to only three water years (2008-2010).
- Flow data excludes the Faka Union Canal, which contributes over half the regional flow.
- Specific row counts, column names, and measurement frequencies for the raw data are not provided.
Provenance
- Source
- U.S. Geological Survey study conducted for the Comprehensive Everglades Restoration Plan.
- Collection Method
- Acoustic Doppler velocity meters and current profilers used at structures; index velocity method applied to compute discharge.
- Time Range
- March 2006 to September 2010, with detailed subbasin analysis for water years 2008-2010.
- Freshness
- Data collection ended in September 2010; it serves as a historical baseline.
- Geography
- Western Tamiami Trail between County Road 92 and State Road 29 in southwest Florida, excluding the Faka Union Canal.
