Lower Mississippi Region Comprehensive Study. Appendix C. Volume I. Regional Climatology, Hydrology and Geology.
Abstract
The purpose of this appendix is to assemble climatologic, hydrologic, and geologic information in a summarized form for use in the planning and development of the water and related land resources of the Lower Mississippi Region. Detailed information on the present quantity, quality, availability, and use of surface water and ground water in each of the 10 Water Resources Planning Areas (WRPA) of the region is presented in this appendix. Included in the regional summary or in each WRPA section are a general hydrologic and geologic description of the area; a detailed description of the climate; and a discussion of water use, stream management practices, water rights, and streamflow characteristics in the area. Streamflow data for selected streams were analyzed and summarized as follows: observed mean discharge for the period of record available at the site; annual peak discharge frequency curves; low flow frequency curves; duration curves of daily flows; lowest mean flows for from 1 to 10 consecutive years during the period of record of streamflow at each station; and seasonal and annual variations in discharge and precipitation. A general summary of ground water resources of the region is presented and discussed in this appendix. Descriptions of the geologic units that form major aquifers and the hydrologic characteristics of the aquifers are included. Potential yield data and data regarding the chemical quality of ground water in the region are presented and discussed in each WRPA section through the use of maps and tables.
