Abstract: | Fort Morgan Peninsula is an attached portion of a dynamic barrier complex in the northern Gulf of Mexico and is a large tourist
area that brings in a significant amount of revenue for Alabama. Many of the hotels and tourist attractions depend on the
groundwater as their water supply. The over-withdrawal of groundwater and saltwater intrustion will have a negative impact
on the ecology, tourism and economy if groundwater resources are not properly monitored and managed. In this study a calibrated
groundwater flow model was used to analyze the sustainability of groundwater resources at Fort Morgan Peninsula. Detailed
flow budgets were prepared to check the various components of inflow and outflow under different water use and climatic conditions.
The results indicated the locations where groundwater was over-pumped and subjected to saltwater intrusion, or will be subjected
to saltwater intrusion under a range of projected water use and climatic conditions. |
