The US Geological Survey, John Wesley Powell Center for Analysis and Synthesis, is offering a funding opportunity to systematically analyze the spatio-temporal variability of land-surface hydrologic fluxes in natural and human-altered watersheds worldwide. The goal is to extend the framework for estimating land-surface fluxes in human-altered watersheds and to relate anthropogenic signatures such as flow alterations and evapotranspiration-induced urban heat island effects using global datasets. Specific objectives include: evaluate existing Budyko frameworks/relationships to explain the spatial variability of seasonal and annual hydroclimatology; quantify the sensitivity of land-surface fluxes to changes in climatic and land-surface controls at global scale; extend the Budyko supply-to-demand framework to capture other signatures of human influence on streamflow (e.g., flow alterations) and evapotranspiration (e.g., urban heat island, irrigation impacts and land use changes); and synthesize the influence of large-scale climate and local/regional anthropogenic influences on watershed-level hydroclimatology.
