Associated Science Experts, LLC and  Structural Integrity Solutions, Inc. offer consulting, forensic testimony, research programs, and studies in the fields of meteorology, hydrology, hydrometeorology, climatology, hydraulics, hydrologic engineering, hydrogeology, and water resources management for the purpose of determining or re-determining the proper, safe size of existing and future dams and their spillways.  The civil engineers, seismologists, and soil specialists of our member organizations can provide studies and investigations into the earthquake safety and structural integrity of existing dams and dams under design.

• FORENSIC DISCOVERY and EXPERT WITNESS TESTIMONY in depositions and court trials, regarding extreme rainfall, Katrina and other recent hurricanes, the safety of dams, or any other meteorological, hydrometeorological, or hydrologic issues, from heavy rain or strong wind to floods or ground water contamination.

Our forensic experts include  Charles B. Pyke, Ph.D., Meteorologist,  William J. Trott, Ph.D., P.E., Hydrologic Engineer,  Timothy E. Wright, Meteorologist and Expert Data Analyst, and other top scientists and engineers.

• PROBABLE MAXIMUM PRECIPITATION  (PMP) determinations.

  • Evaluation of existing PMP criteria in light of recent storm events and meteorological studies.

  • Determination of revised PMP for new and existing dams and spillways.

• PROBABLE MAXIMUM FLOOD  (PMF) determinations.

  • Evaluation of existing PMF criteria in light of revised PMP and updated flood routing criteria.

  • Determination of revised PMF for new and existing dams and spillways.

  Our PMP and PMF research hydrometeorologists and hydrologists include  Ed Tomlinson, Ph.D.,  Charles B. Pyke, Ph.D., William J. Trott, Ph.D., P.E.,  Timothy E. Wright,  Philip K. Barone,  and Lawrence D. Bregman.

• FLOOD-WARNING SYSTEMS.

• Other direct-reading and remote-reading meteorological and hydrologic instrumentation systems.

• RESEARCH and STUDIES.

• Storm studies, Part I and Part II. 

  • Part I:  Detailed meteorological isohyetal analyses of major historical storms, including recent storms:

    • Hurricanes Katrina and Rita, 2005, in Louisiana and Mississippi, plus other 2005 hurricanes..

    • Hurricanes of 2004 in Florida and northward through the eastern Atlantic states.

    • Other major hurricanes of the past 20 years.

    • Major mid-latitude flood-producing storms, including those of 1993 in the Great Plains.

  • Part II:  Detailed depth-area-duration (DAD) analyses; DAD curves (graphic and digital) from Part I storm isohyets for use in the development of Probable Maximum Precipitation (PMP) for dam safety considerations and in other reservoir and channel design.

• Spillway design: ability to pass probable maximum flood flow - updated criteria.

• Reservoir design: ability to store probable maximum flood volume, in conjunction with spillway flow - updated criteria.

• Hydrometeorological research and studies, geared toward determination of PMP, as well as other major design storms.

  • General mid-latitude storms.

  • Hurricanes.

  • Extreme local thunderstorms.

    • Air-mass thunderstorms - deserts.

    • Air-mass thunderstorms - humid areas.

    • Orographic thunderstorms - mountain areas. 

    • Heavy thunderstorms embedded in hurricanes.

    • Heavy thunderstorms embedded in mid-latitude general storms, especially along cold fronts.

• Dam safety, dam and levee structure studies.

• Dam and levee failure inundation maps.

• Dam failure - public awareness programs.

  • Contingency preparedness by officials and by public.

  • Evacuation studies and planning.

    • Determination of feasibility of mass evacuations below various reservoirs.

    • Planning for, and design of, implementation of evacuation measures.

  • Flood-control channel design; ability of channels to handle extreme flood flows.

  • Rainfall frequency determinations:  durations from 1 minute to 10 days - updated criteria.

  • Flood frequency analyses: 

    • Peak river levels; annual maximum flow rates.

    • Maximum reservoir levels or storage volume.
