The Effects of Land Use and Climate Change on the Water Yield of a Watershed in Colombia Open
Land use and climate are two determinant factors of water yield within a watershed. Understanding the effects of these two variables is key for the decision-making process within watersheds. Hydrologic modeling can be used for this purpose…

Socioeconomic and Environmental Proxies for Comparing Freshwater Ecosystem Service Threats across International Sites: A Diagnostic Approach Open
In this work, we develop and test proxy-based diagnostic tools for comparing freshwater ecosystem services (FWES) risks across an international array of freshwater ecosystems. FWES threats are increasing rapidly under pressure from populat…

Synoptic Sampling to Determine Distributed Groundwater‐Surface Water Nitrate Loading and Removal Potential Along a Lowland River Open
Delineating pollutant reactive transport pathways that connect local land use patterns to surface water is an important goal. This work illustrates high‐resolution river mapping of salinity or specific conductance (SC) and nitrate ( ) as a…

Toward the Geoscience Paper of the Future: Best practices for documenting and sharing research from data to software to provenance Open
Geoscientists now live in a world rich with digital data and methods, and their computational research cannot be fully captured in traditional publications. The Geoscience Paper of the Future (GPF) presents an approach to fully document, s…
