Wetland Hydrology


Wetlands provide benefits to humans for water quality and clarity, flood protection, and recreation. Learn about one of the most significant driving forces in the formation, function and ecology of a wetland.  

Cover the basic definitions and benefits of wetlands, how wetlands are delineated, and indicators of wetland hydrology. The more advanced materials will include understanding wetland hydroperiods, how wetlands are connected to ground water and surface waters, how hydrology influences the formation of hydric soils and acts as a force that structures plant communities, how wetland hydrology influences nutrient flow, the effects of storm water on wetlands, and restoring wetland hydrology.

Plus, put your boots on the ground and take a tour of some wetlands including one of Wisconsin Wetland Association’s Wetland GemsTM.

Notes on the Field Trip What better way to learn about wetland hydrology than to get your feet wet? Be prepared to walk a half-mile or more on unpaved surfaces and boardwalks during the day. We may choose to venture into areas with saturated soil or standing water, so wear footwear you are willing to get wet. It is recommended that you wear long pants and consider bringing along insect repellent. The field trip will take place rain or shine; so please be ready.

Who Should Attend

Municipal staff, engineers, landscape architects, developers, land managers, entry level natural resource consultants, students, and anyone interested in learning more about wetland hydrology and wetland ecosystem services.

Ronald A. Londré, PWS, is a Senior Ecologist at an environmental consulting company (TRC Environmental Corporation) with over nine years of professional experience in wetland ecology. He is certified by the Society of Wetland Scientists Professional Certification Program as a Professional Wetland Scientist (PWS # 2436) and is certified by the Ecological Society of America as an Ecologist. His wetlands work has included wetland delineations, wetland functional and floristic assessments, wetland restoration design, and wetland restoration monitoring. His academic studies, from which he earned M.S. and B.S. Degrees in Biological Science, focused on plant community ecology and restoration ecology. Prior to becoming a consultant, Ron was a college instructor and research scientist teaching principals of biology, environmental science, and botany while studying the forces that structure plant communities and restoration ecology.


Geoffrey B. Parish, P.G., P.H., is a hydrologist and geologist for a Milwaukee-based consulting company (GRAEF), with M.S. and B.S. degrees in geosciences from the University of Wisconsin-Milwaukee. He has studied wetland hydrology and soils in Wisconsin and Illinois for almost twenty years. His wetland work has included wetland delineations; wetland hydrology evaluations; sources of deposition in wetlands; long term monitoring; evaluation of possible impacts from proposed urban developments, roads and excavations; and wetland mitigation projects including enhancements, restorations and creations. He has developed hydrologic models of natural systems including wetlands systems to evaluate existing and planned conditions. In addition to wetland projects he has worked on river management planning, lake water quality management planning, ordinary high water mark determination studies, and soil moisture. He was a graduate teaching assistant in the University of Wisconsin-Milwaukee Geosciences Department, and has presented on natural area hydrology at workshops and numerous conferences.
