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 30 September 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 January 2029.

Abstract

Immersed granular materials such as river and seabed sediments and industrial slurries consist of small particles dispersed in a liquid. When these particles stick together, the bulk behavior of the slurry becomes highly complex. These cohesive effects determine whether a riverbed erodes, a coastal slope collapses, or an industrial process is successful. Despite its importance, predicting the bulk behavior of…
