green arrow Technical Assistance

NHGS provides assistance relative to assessing and addressing flood hazard risks. For information regarding the flood and geologic hazards program, or questions relating to river geomorphology, contact Shane Csiki at NHGS: (603) 271-2876 or shane.csiki@des.nh.gov.

The program is home to the state-owned river modeling flume, which shows how rivers work, and how actions undertaken on a river, such as undersized culverts, can affect river processes. Demonstrations are primarily tailored to community officials. If you have questions, or would like to schedule a flume demonstration, contact Jeremy Nicoletti at NHGS: (603) 271-5762 or jeremy.nicoletti@des.nh.gov.
