Abstracts

We are now accepting abstracts for our 2026 event. Submissions are being accepted through May 29. 

Schedule

The complete schedule will be posted in late July. INAFSM is currently accepting abstract submissions (deadline is May 29).

For ECI Certified Professionals: INAFSM conference sessions approved by Envirocert for professional development hours (PDHs) include basic and advanced sessions focusing on the physical and natural sciences, as well as hydrology, engineering and other specialty areas. We will not know which 2026 sessions are pre-approved until after the complete schedule is submitted by Envirocert. Here is a list of all 2025 INAFSM Annual Conference sessions that have been approved by Envirocert. 

Tracking PDHs

For those who need to track professional development hours, we'll post a PDF Tracker you can download for your records to self-check the sessions you attend. The tracker will be posted here after the schedule is completed. Looking for your hours from 2020, 2021, 2022, 2023, 2024 or 2025? You can access your history and print out a certificate by clicking on the "My CEUs" link (at top of this page). 

Scholarships

Two scholarships will be awarded, one for someone working in floodplain management and one for someone working in stormwater management. In addition to the registration fee, this scholarship includes most meals at the conference. Hotel registration, travel expenses, and any other conference related expenses or incidentals are the sole responsibility of the scholarship winner. Winners will be expected to volunteer as needed during conference. If an individual has already registered for the conference, we will refund the registration fee if he/she is selected as a scholarship recipient. Application deadline is June 13 (application form coming soon)

Just think about items on which you might like to bid; if the item or collection of items is interesting to you, then there's a good chance that others will be interested, too. Please contact Suzie Delay or call (317) 234-1063) to make a donation or request more information.
