Hydrologic Sciences (HS)

The Hydrologic Sciences Program is a disciplinary program within the Division of Earth Sciences. Hydrologic science has a distinct focus on continental water processes at all scales, and the program supports research with a primary focus on these processes. The program supports fundamental research about water on and beneath the Earth’s surface, as well as relationships of water with material and living components of the environment. A major focus is the study of hydrologic processes (e.g., rainfall and runoff; infiltration and subsurface flow; evaporation and transpiration), as well as fluxes of water (e.g. in soils, aquifers, and streams). Many projects involve the study of hydrologic transport (e.g., of dissolved solutes, sediment), coupling of hydrological processes with other systems (e.g., ecosystem processes, geochemical cycles, food and energy systems, socio-ecological systems), or hydrologic responses to change (e.g., changes in land use, climate, or watershed management). Observational, experimental, theoretical, and modeling approaches are supported.

*Who May Submit Proposals: Proposals may only be submitted by the following: -Non-profit, non-academic organizations: Independent museums, observatories, research laboratories, professional societies and similar organizations located in the U.S. that are directly associated with educational or research activities. -Institutions of Higher Education (IHEs) - Two- and four-year IHEs (including community colleges) accredited in, and having a campus located in the US, acting on behalf of their faculty members.Special Instructions for International Branch Campuses of US IHEs: If the proposal includes funding to be provided to an international branch campus of a US institution of higher education (including through use of subawards and consultant arrangements), the proposer must explain the benefit(s) to the project of performance at the international branch campus, and justify why the project activities cannot be performed at the US campus.
