* The Hydrometeorology Associates is an association of meteorologists and scientific companies.
Probable Maximum Flood (PMF) determinations.
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. Hydrometeorological research and studies, geared toward determination of PMP, as well as other major design storms.
Dam safety, dam and levee structure studies. Dam and levee failure inundation maps. Dam failure - public awareness programs.

Other hydrometeorological and civil engineering consulting and research
services pertinent to dam safety:
Heavy precipitation research, studies, and
modeling.
Radar rain rate determinations, including NEXRAD interpretation.
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. 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. For more information about these and other services of The Hydrometeorology Associates, contact:
