Integrated Hydro Systems, LLC (IHS), established in 2002 by Robert H. Prucha, PhD, P.E. and Dr. Tissa Illangasekare PhD, P.E., is a small, but focused consulting-engineering company, offering practical, defensible and cost-effective solutions to complex environmental and water resources problems.

Over the past few decades, rapid changes in environmental, social, economic, legal and political factors have produced increasingly more complex environmental and hydrologic problems. As a result, solving these problems requires increasingly more sophisticated techniques and technology. Over this same time period, dramatic improvements in computers, data collection, mapping/GIS and analytical tools have enabled engineers to address more complicated problems. Integrated Hydro Systems uses state-of-the-art methodology and technology to provide clients with innovative and effective solutions to increasingly complex problems.

Our specialized academic backgrounds and professional experience allows us to provide solutions to more complex problems more effectively than many consultants. We have considerable experience project experience involving both subsurface and surface water flow systems, at a variety of scales (lab to regional-scale), and in a variety of environments/climates (humid to arid). We utilize a variety of advanced commercial and research software to solve challenging problems for clients.
