Detailed Project Report and Environmental Assessment on Upper Gordons Creek, Urban Flood Damage Reduction Measures at Hattiesburg, Mississippi.

A Detailed Project Report DPR was prepared to determine the need for Federal participation in a project to modify the flood conditions in Hattiesburg, Miss. The studies presented in this report cover the Gordons Creek drainage basin, its flood problems, and the potential for solving such problems. All reasonable alternative plans for flood damage reduction were considered. Although the study concentrated on damages associated with flooding, other areas of water resource planning were also investigated, which were socio-economic profile, Field investigations were made to develop assessments of flood damages, soil conditions, and flood control measures which would be necessary to alleviate flooding problems. Stream discharges in the basin were determined by use of an HEC-1 computer model to stimulate the rainfall - runoff process. The water surface profiles were developed through the use of an HEC-2 computer model. The report has a Main Report section which includes the Environmental Assessment and which is supported by appendices for Socio-Economic Investigations, Engineering Investigations, Plan Formulation, Environmental Investigations, and Public Involvement and Coordination.
