Blending the sciences of meteorology and hydrology for the study of rainfall, snowfall, snowmelt, and runoff

as they affect water resources, floods, and the safety of dams - all in the interest of saving lives, protecting

property, and ensuring adequate water supplies to urban, agricultural, and environmental interests.

Offering services to:  Federal Agencies, the U.S. Military, State Governments, County and City Officials, Local Communities, Farming Interests, Shipping and Boating Interests, Construction Companies, Engineering Companies,  Environmental Concerns,  Fire Officials,  Recreational Organizations and Individuals,  and  many  others.

Hydrometeorology:   A "branch of meteorology that deals with problems involving the hydrologic cycle, the water budget, and the rainfall statistics of storms. The boundaries of hydrometeorology are not clear-cut, and the problems of the hydrometeorologist overlap with those of the climatologist, the hydrologist, the cloud physicist, and the weather forecaster. Considerable emphasis is placed on determining, theoretically or empirically, the relationships between meteorological variables and the maximum precipitation reaching the ground. These analyses often serve as the bases for the design of flood-control and water-usage structures, primarily dams and reservoirs. Other concerns of hydrometeorologists include the determination of rainfall probabilities, the space and time distribution of rainfall and evaporation, the recurrence interval of major storms, snow melt and runoff, and probable wind tides and waves in reservoirs. The whole field of water quality and supply is of growing importance in hydrometeorology."  -  The New Encyclopaedia Britannica (1987)

The Hydrometeorology Associates (an association of meteorologists and scientific companies) offer a variety of meteorological, hydrologic, and hydrogeologic consulting services to governmental agencies and private interests, especially with respect to the safety of dams, levees, and other hydraulic structures in the interest of saving lives and reducing property damage from floods.

Included are Forensic Discovery and Expert Testimony, and  investigations into, and studies of:

The adequacy of existing Probable Maximum Precipitation (PMP) determinations, and the resulting Probable Maximum Flood (PMF) determinations, for dams built years ago, plus the development of new PMP and PMF criteria for new dams to be built or for older dams to be renovated.

Flood frequency analysis and reservoir level frequency analysis for existing dams, levees, and channels, as well as those under design and those under consideration for renovation.

Storm Studies, Parts 1 and 2, for recent and historical major storms and hurricanes, including Hurricane Katrina.

Drought frequency analysis for specific watersheds and water-supply reservoirs.
