Remotely sensed surface water storage shows distinct patterns from SWAT-simulated data Remotely sensed surface water storage shows distinct patterns from SWAT-simulated data
Quantifying and projecting the downstream benefits of water stored in lakes and wetlands (SWstorage) requires watershed hydrologic models, which often parameterize surface water storage in topographic depressions using static digital elevation model (DEM) data. Calibration and validation of modeled SWstorage dynamics using external data sets is uncommon, particularly across major river...
Patterns of rift basin development and the fidelity of the subsidence record: Insights through Bayesian modeling of rapid tectonic subsidence in a Rio Grande rift basin, Socorro, NM, U.S.A Patterns of rift basin development and the fidelity of the subsidence record: Insights through Bayesian modeling of rapid tectonic subsidence in a Rio Grande rift basin, Socorro, NM, U.S.A
Characterizing tectonic subsidence rates within depositional sequences provides direct insight into the driving mechanism(s) of accommodation in a basin. However, the temporal resolution of this record is often stymied by a lack of high-precision and high-resolution ages, which enable a more complete description of basin subsidence drivers. We explore the effect of high-precision and...
Methodology for construction of a three-layer geologic model of the conterminous United States using land surface, top of bedrock, and top of basement Methodology for construction of a three-layer geologic model of the conterminous United States using land surface, top of bedrock, and top of basement
This report describes the methodology used for the construction of a digital three-layer geologic model of the conterminous United States by mapping the altitude of three surfaces: land surface, the top of bedrock, and the top of basement. These surfaces are mapped through the compilation and synthesis of published stratigraphic horizons from numerous topical studies. The mapped surfaces...
