Ohio Sea Grant's January 2025 Freshwater Science webinar.
Ohio has over six million acres of soils that are poorly or somewhat poorly drained, often posing a challenge for implementing on-site wastewater systems and stormwater systems. Dr. Vinayak Shedekar from The Ohio State University, through a Harmful Algal Bloom Research Initiative project, is developing a state-wide decision tool that will use county-level weather records and location-specific soil data to assist designers of stormwater and onsite wastewater systems.
The tool allows designers to predict water table dynamics and drainage discharge with the help of DRAINMOD, a two-dimensional, hydrologic model. Through that model, a septic system designer can select an optimum drain spacing and depth that can help minimize interactions with groundwater and consequently minimize the impact on downstream water quality. Stormwater system designers can also use the same tool for location specific water budgets, especially drainage discharge predictions. Learn more about the tool and examples during this webinar.
