Bill Katzenmeyer

William Mark (Bill) Katzenmeyer, P.E., C.F.M. is Senior Water Resources Technical Lead for C.H. Fenstermaker and Associates, LLC.  Bill specializes in hydrologic and hydraulic modeling, automation, and the practical application of Large Language Models (LLMs) in engineering practice.   As a Professional Engineer and Certified Floodplain Manager, Bill also has expertise in floodplain mapping and risk management, flood impact analysis, benefit cost analysis, and the management of FEMA Hazard Mitigation Assistance grants and programs.

Bill is the developer and primary author of the HEC-Commander tools, an open-source collection of python notebooks authored through natural language instruction with the assistance of ChatGPT.  Published in November 2023, these tools serve as an early success story and framework for leveraging LLMS to code automation scripts for water resource engineering workflows.  These tools include RAS-Commander, the first open source published tool capable of automated parallel execution of HEC-RAS plans across multiple Windows-based machines.

Bill also serves on the American Society of Civil Engineers (ASCE) Coast Ocean Ports and Rivers Institute (COPRI) Ports and Harbors Committee, Sea Level Change Subcommittee and Waterways Committee.
