The Impact of Land Use Changes on the Salt Regimes of Georgia Estuaries
Support: Georgia Coastal Incentive Grant (GA Dept of Natural Resources, Coastal Resources Division)
2) An analysis of precipitation and runoff records for the Satilla River watershed on the Georgia coast was conducted, and found a marked increase in the variability of yield values for winter storms. As hydrographic yield is strongly influenced by land use, this pattern suggests that seasonally changing land uses (or land uses in which the land cover changes on a seasonal basis) may significantly be affecting runoff patterns in the Satilla basin;
3) Salinity patterns in the Satilla River were analyzed during both high and low-discharge events. There was a large variation in the salinity regime of the Satilla River Estuary over the course of these observations, and they were used to demonstrate that the salinity regime of the estuary responds almost immediately to changes in discharge;
4) The Satilla data were used to assess a finite-element model developed at SkIO under State support. The study found that this model could not accurately simulate tidal and salinity conditions in the Satilla River estuary;
5) There is now
extensive field work being conducted to measure salinity, temperature, pressure,
and currents in the Ogeechee River.
