Important information for proposers

All proposals must be submitted in accordance with the requirements specified in this funding opportunity and in the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. It is the responsibility of the proposer to ensure that the proposal meets these requirements. Submitting a proposal prior to a specified deadline does not negate this requirement.


Hydrologic Sciences (HS) focuses on terrestrial processes that comprise the hydrologic cycle including evapotranspiration, precipitation, infiltration, overland and streamflow, subsurface percolation and the transport of solutes, nutrients, and particles by these fluxes. This program encourages studies probing the spatial and temporal heterogeneity of water and chemical fluxes and storages from local to global scales – including residence times, interfacial fluxes, pathways among system compartments, and research in geolimnology and hydrologic impacts on microbial communities. HS also supports research in aqueous geochemistry directly connected to hydrologic processes and the physical, chemical, and biological processes taking place as water bodies change. Since the study of hydrologic processes requires expertise from many basic sciences and mathematics, HS encourages interdisciplinary proposals and joint review with related programs.
