Abstract:
The research study was sectioned into 5 separate tasks. Task 1 included defining the seasonal high ground water table (SHGWT); describing

methods and techniques used to determine SHGWTs; identify problems associated with estimating SHGWT conditions; summarizing results from

interviewing state agencies and engineering consultants for determining how SHGWTs are determined; and, providing a preliminary data set for

developing a technical procedure manual for applying various SHGWT predictive methods.

Task 2 characterized pilot test site locations by describing procedures for establishing ten (10) physical and four (4) hypothetical tests sites using future

road construction corridor projects. The procedures section described multiple sets of methods in order to evaluate method consistencies between test

site methods, topographical, and hydrogeological conditions.

Task 3 was divided into three tasks- Task 3A, 3B, and 3C. Task 3A provided a summary of field and analytical methods used to evaluate baseline SHGWT

conditions during setup of both physical and hypothetical test sites. A preliminary evaluation of methods used to predict SHGWT conditions at each test

site was included. Task 3B involved collection of water level data from test well and surface water locations along with hydrologic station data to evaluate

various equation methods for estimating SHGWT conditions. Task 3B covered a two year long term monitoring program involving the collection of water

level data and applying model equations to both ground water and surface water observation sites, and nearby hydrologic stations for evaluating SHGWT

predictive methods. Quarterly status reports were prepared summarized field collected data and equation evaluation methods. Task 3C addressed the

issue of applying the NRCS water table ranges for specified soil types throughout the seven (7) FDOT districts by compiling ground water and rainfall data

from available water management district records. The data was evaluated for statistical probabilities for applying NRCS water table ranges for predicting

ground water levels by direct comparison with actual ground water level data.

Task 4. Report of Recommendations summarized the most successful methods for predicting seasonal high ground water elevations through application

of both qualitative and quantitative methods for each FDOT District based on data collected over the three year study. Task 5. The Draft and Final Report summarized the research study tasks as described above.
