Teton Dam, ID Failure, June 5, 1976 * The Hydrometeorology Associates is an association of meteorologists and scientific companies.
PROBABLE MAXIMUM PRECIPITATION (PMP)
PROBABLE MAXIMUM FLOOD (PMF)
Determination of revised PMF for new and existing dams and spillways. Storm studies, Part I and Part II.
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. FLOOD-WARNING SYSTEMS. Other direct-reading and remote-reading meteorological and hydrologic instrumentation systems. Hydrometeorological research and studies, geared toward determination of PMP, as well as other major design storms.
Dam safety, dam and levee structure studies. Maximum Credible Earthquake criteria Dam and levee failure inundation maps. Dam failure - public awareness programs.
Other hydrometeorological and civil engineering consulting and research services pertinent to dam safety:
Hurricane research and studies; hydrometeorological aspects of hurricanes. Potential effects of possible global warming on hurricane frequencies and paths. Effects on PMF of mud and debris flows from burned watersheds Infiltration rates: studies of watersheds above reservoirs, especially minimum infiltration rates at times of PMP events. Effects of cloud seeding upon water yield - significant if cloud seeding happens to precede an extreme rainfall event. Drought duration studies - for purposes of sizing the maximum water-supply storage needed in a reservoir and the available flood-control space for the storage of a PMF event. Global warming / cooling; climatic change - natural and man-made; possible effects upon Probable Maximum Precipitation. Soil studies, research and experiments on soil compaction - relative to safety of dams and their foundations. Examination of existing dams for integrity of structure:
Design storms for flood control and water resources. Flood plain management studies. Flood warning system design. Snowfall and snow hydrology research and studies; snow sublimation. Snow melt research and studies; rates of snow melt under various meteorological conditions; flood potential of snow melt, contribution of snow melt to PMF (very large or very high altitude watersheds only). Flood preparedness, including spillway flow (other than dam break): official planning; public awareness and planning. Severe storm and
hail research and studies.
Water resources research and studies; stochastic watershed analysis. Reservoir water control manuals;
hydrologic manuals. Climatic studies of normal and extreme precipitation. Cloud physics, cloud dynamics: research, modeling. Geographic Information System (GIS) mapping expertise. Tsunami warning system design. For more information about these and other services of The Hydrometeorology Associates, contact: Edward M. Tomlinson, Ph.D, Principal Hydrometeorologist:
