Our expertise in geotechnical engineering, hydrology and hydraulics, and risk management makes Geosyntec the go-to provider for a wide range of technical services for new and existing dams, dikes, levees, and other hydraulic containment structures. Our practice innovators develop tailored solutions to respond to unique challenges facing municipal, industrial, and other public and private owner/operators. Our designs have a reputation for efficiency, cost effectiveness, simplicity of operation and maintenance, and endurance. Our services include:

  • Engineering Planning and Design;
  • Condition Inspection;
  • Construction Support;
  • Analysis and Evaluation;
  • Risk Assessment and Risk Management;
  • Regulatory Compliance.

Specific examples of our services are:

  • Engineering design and design review of new structures and rehabilitation and enhancement of existing facilities;
  • Application of risk-informed approaches to estimate the likelihood of failure, consequences in terms of life safety and economic losses, and tolerable risk;
  • Performance assessment of existing structures using state-of-the-art modeling and analytical methodologies to evaluate structural integrity under a variety of loading conditions;
  • Inspection, condition assessment, and stability and seepage analysis of earthen dams and levees;
  • Inspection, condition assessment, and stability and structural analysis for concrete, roller compacted concrete, appurtenant hydraulic structures, and arch and gravity dams;
  • Analyses to evaluate the performance of earthen structures during seismic events, including the potential for loss of strength due to liquefaction;
  • Hydrologic and hydraulic modeling and engineering in support of dam, dike, and levee design, including computational fluid dynamics (CFD);
  • Hydrologic and hydraulic modeling and studies to assess flood inundation mapping, maximum probable flood impacts, emergency action plan preparedness and potential long-term flood storage capacity, including with regard to potential effects of climate change;
  • Temperature and water quality modeling and studies to support management strategies to improve water quality and meet regulatory compliance criteria using state-of-the-art and -practice numerical models including near fielding modeling and computational fluid dynamics (CFD) for complex geometries and plume mixing analyses;
  • Federal Energy Regulatory Commission (FERC) hydropower license amendments and environmental compliance services expediting dam rehabilitation;
  • Fisheries and water quality investigations, and hydrodynamic, water quality, and sediment modeling;
  • Construction management, construction oversight, and comprehensive construction quality assurance (CQA) using advanced information management systems (IMS);
  • Rehabilitation of existing structures, including feasibility analyses for development of practical alternatives and implementation of selected remedial options; and
  • Design of levees, dams, and other retaining structures associated with cooling waters and management of residuals.
