Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 August 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

This grant supports research that looks to advance the knowledge of how fluid-coupled granular media behave. Because granular media are ubiquitous in natural systems (such as soils in riverbeds and landslides) and infrastructure (such as concrete and ballast), this research will promote both the progress of science and engineering, as well as advance national prosperity. When a load is applied to a granular medium,…
