Our Mission

Coastal Environments is committed to offering the best and most efficient oceanographic, coastal engineering, and environmental consulting services in the industry. To meet this goal, we navigate among interrelated disciplines including engineering, physical oceanography, hydrology, marine biology, climate science, coastal geology, planning, permitting and communications to facilitate cost-effective solutions. We are dedicated to the success of our projects – today, tomorrow and far into the future.


Coastal Environments has conducted projects all over the world, including the United States, Mexico, the Middle East, the United Kingdom, South America, and North Africa. Our associates are versed in many languages, including English, Spanish, Arabic, and German. We possess a strong commitment to our clients, which include private industry, municipalities, state and federal agencies, private foundations, and nongovernmental organizations (NGOs).

Coastal Environments is a trade representative (agent) for several oceanographic instrumentation firms and has many colleagues who serve as technical advisors available to assist in the implementation of various field studies.

Recent clients include:

  • Coastal Environments' involvement has been critical to the success of the San Dieguito Lagoon restoration, one of the largest lagoon monitoring programs ever conducted on the coast of Southern California.

    Southern California Edison
  • Coastal Environments constructed an artificial reef within the time limits required by the permit and fulfilled the design criteria well within the planned tolerances. We are all very happy with the configuration of the experimental modules.

Hany Elwany, Ph.D.

Founder and President

MASCE, Engineer, Oceanographer and Hydrologist

Dr. Hany Elwany is among the world’s foremost scientists and engineers in the nearshore environment, with specialized experience in coastal processes, sediment transport and estuarine dynamics. He founded Coastal Environments in 1988 to provide unprecedented professional services to meet coastal challenges. Dr. Elwany has authored and employed unique mathematical and computer techniques to study optimal design structures under various dynamic constraints. His work includes dynamic response of mechanical systems, design of offshore structures, data analyses, simulation, modeling of ocean and coastal conditions and the interaction between currents, waves and structures. Dr. Elwany holds a Ph.D. from the University of Dundee in the United Kingdom, a B.S. in Mathematics and Statistics from Alexandria University, and has worked extensively with the Center for Coastal Studies at the Scripps Institution of Oceanography.
