NSF lists this award's end date as 31 December 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 30 April 2029.

Abstract

Understanding how mixtures of solid particles and fluids, such as those found in avalanches, volcanic flows, and river sediments, initiate and how fast they propagate is vital for natural hazards and improving engineering models of Earth systems. These particle-laden flows are complex because the solids and fluids interact in diverse ways: sometimes the mixture acts like a solid, other times like a liquid, and often…
