“…1b) from the river mouth to the saltwater intrusion limit where the bottom 0.5-ppt isohaline resides. The use of 0.5 ppt is consistent with Chen (2004) and Bao and Liu (2008) as 0.5 ppt is a criterion for drinking water.…”

“…Similar to many other narrow riverine estuaries such as the lower Alafia River Estuary [5], Tanshui River estuary [6], as well as the lower Peace River and tidal Caloosahatchee River in the Charlotte Harbor estuarine system [7], the transversal variations of flow, salinity, and temperature in the Chassahowitzka River estuary are much smaller Physical processes such as circulations, salinity transport processes, and thermal dynamics in the Chassahowitzka River estuary have never been thoroughly studied before and there exists very limited effort on hydrodynamic modeling of the estuary in literature. Dynamic Solutions [3] used the 3D model EDFC, or the Environmental Fluid Dynamics Code, developed by Hamrick [4] to simulate hydrodynamics in the Chassahowitzka River estuary.…”

This paper presents calibration and verification of the laterally averaged model for estuaries (LAMFE) for the Chassahowitzka River, a spring-fed estuary located on the Gulf coast of central Florida, USA. The river is a narrow and complex riverine system that receives submarine groundwater discharges (SGDs), which are difficult to measure. This study tried to make a reasonable estimate of some unquantified or missing SGD data with a trial-and-error approach in the model calibration process. The model was successfully calibrated against measured real-time data of water level, salinity, and temperature at three locations within the simulation domain from November 2012 to December 2015, before it was verified for the period from January 2016 to March 2017. Skill assessment of the model performance included visual comparisons and statistical quantifications of the difference between measured real-time data and model results. Both have shown that the LAMFE model performs well in simulating hydrodynamics, salinity transport, and thermal dynamics in the estuary. The good agreement of model results with field data suggests that the estimation of unquantified or missing SGDs in the spring-fed estuary is reasonable.

“…Bell Creek, Turkey Creek, and Fishhawk Creek are the minor tributaries that discharge to the lower reaches of the Alafia River. The river is tidally influenced for 18 km from its mouth (Chen, 2004). Lithia Spring, a second magnitude spring (10‐100 ft 3 /s) (Spechler and Schiffer, 1995) and Buckhorn Spring contribute a major portion of the river’s discharge during the dry season (SWFWMD, 2007).…”

Spatial distribution of land use can have a substantial effect on surface and groundwater quality. Our objective was to test for trends in flow components and water quality related to changes in land use in the Alafia and Hillsborough River watersheds in Florida, USA, over the period 1974‐2007. In addition, water quality statistics were evaluated in the perspective of numeric water quality criteria and proposed reclassification of segments of the Alafia River. Trends in 10 water quality parameters and three discharge variables were evaluated using a nonparametric trend detection test. Results of land use analysis indicated substantial urbanization and loss of agricultural land in the study area. Discharge variables did not exhibit significant trends, whereas trends in the majority of water quality concentrations were negative or nonsignificant with total nitrogen and total Kjeldahl nitrogen as exceptions showing positive trends. Changes in nutrient pathways could not be clearly identified. Considering recently promulgated numeric nutrient criteria and standards for dissolved fluoride, much of the Alafia River was found to be out of compliance. While there were land use changes and changes in water quality over the study period, it was difficult to identify a direct cause‐effect relationship. Responses to regulatory efforts, such as the Clean Water Act and improvements in phosphate mining practices, may have had greater impacts on water quality than changes in land use.
