Flood Studies

Dam Removal AssessmentESS has developed the capabilities to assist our clients with investigating flooding issues, assessing the risk, and developing mitigation solutions for flood hazards. Our experience has included preparing FEMA map revisions and evaluating the aquatic resource impacts associated with dam removal to developing visualizations of the extent of inundation resulting from sea level rise in a coastal community. We utilize GIS analytical tools, hydrologic and hydraulic models, and comprehensive field surveys to assess and develop mitigation plans to reduce the damage and economic impact of flooding.

ESS expertise for conducting flood studies includes:

  • Stream Flow Monitoring
  • Hydrologic and Hydraulic Modeling
  • Drainage Studies and Design
  • Flood and Coastal Hazard Analysis
  • FEMA Map Revisions – CLOMR/LOMR
  • Dam Removal Feasibility Studies
  • Sediment Sampling and Management Plans
  • Aquatic Resource Assessments
  • GIS Analysis and Mapping
  • Instream Flow Modeling and Monitoring
  • Hazard Mitigation Planning
  • Civil/Site Engineering Design

Flood Hazard Assessments

ESS water resource engineers and scientists have addressed flood hazards associated with rivers and stream flooding, dam failures, coastal storm surges, tropical storms, and hurricanes. These efforts have included characterization of flood and natural hazards, vulnerability assessments, identification of mitigation measures, and preparation of Hazard Mitigation Plans. We have worked collaboratively with our clients to identify practical hazard mitigation strategies, maintaining natural buffers along rivers, streams and coastal features to provide long-term protection, elevating structures to reduce flooding damage, removing barriers to unrestricted flow, and installing and repairing coastal structures to dampen effects of storm surge.

Dam Removal Studies

The efforts to remove dams to reduce flood risk and restore ecological functions are gaining more support and funding from federal and state resource protection agencies. In fact, many aging dams pose a high risk of failure and are no longer economically practical or cost-effective to operate and maintain. Our water resource engineers, aquatic ecologists, and environmental scientists have expertise in preparing dam removal feasibility studies, assessing flood risks, conducting stream flow and sediment surveys, and evaluating the ecological impacts of fish, benthic, and wetland habitats.
