Development of an Integrated Surface and Subsurface Model of Everglades National Park

Abstract

analysis showed that the model was most sensitive to the hydraulic conductivity of the regional Surficial Aquifer System, the Manning's roughness coefficient, and the leakage coefficient, which defines the canal-subsurface interaction. The model offers an enhanced predictive capability, compared to other models currently available, to simulate the flow regime in ENP and to forecast the impact of topography, water flows, and modifying operation schedules.

Simulating Everglades National Park hydrology and phosphorus transport under existing and future scenarios using numerical modeling

“…Calibration for the M3ENP was performed for several subdomains within the model domain to determine sensitive parameters such as Manning's number and hydraulic conductivity (Cook, 2012). Model best fit was evaluated using stage and discharge observed data at over 100 sites within the model domain for the 2000 to 2010 period.…”

“…Other Everglades modeling efforts focus on improved spatial and temporal resolution (Bolster and Saiers, 2002;Langevin et al, 2005), increased vertical discretization for detailed subsurface studies (Chui et al, 2011), and enhanced parameter estimations such as hydraulic resistance (Bolster and Saiers, 2002;Min et al, 2010). However, there re- (Cook, 2012) and to better understand the impacts of historical and proposed structural operations. The domain for the M3ENP model is shown in Figure 3.1.…”

“…Once the relationships between the spectral reflectance of the vegetation and the vegetation type and productivity are established, information about the nutrient content in the surrounding area can be inferred. Some ecosystem components such as vegetation and water can be directly measured with remote sensing; however, information such as total phosphorus content in soils and floc must be inferred via statistical relationships to spectral data (Rivero et al, 2009 successfully simulated surface and groundwater flows and levels within ENP (Cook, 2012). In Chapter 3 of the present research, the M3ENP model is used to explore the effects of bridge construction and canal water level increases on ENP water levels and flows.…”

“…Therefore, only minimal technical details of the model development will be included in this paper. For a more detailed technical description of the M3ENP model, please refer to Cook (2012).…”

“…Channel cross sections were determined from topography data and design as-builts. Channel structures such as culverts, weirs, gates and pumps were developed based on designs obtained from SFWMD and DERM as described in Cook (2012). Canal water level inputs were obtained from NPS, SFWMD, or USGS.…”
