PRMS simulator used to assess rainfall, runoff, and river flow for the National Hydrologic Model (NHM) Puerto Rico

The National Hydrologic Model (NHM) is a modeling framework which has been applied to the continental United States through the Precipitation Runoff Modeling System (PRMS). The PRMS model of Puerto Rico extends the NHM and allows the simulation of rainfall-driven hydrologic conditions in the Commonwealth. Calibration of the NHM Puerto Rico model involved an initial manual calibration to understand the important processes and develop a basic representation of the hydrology. This is followed by an automated calibration procedure using the Let Us CAlibrate (LUCA) multi-objective function model calibration tool. A four-step procedure is used in Luca to separately calibrate parameters for solar radiation, evapotranspiration,...

Florida is home to 50 endangered species, 23 National Wildlife Refuges, 9 national parks, and 119 state parks. Straddling both temperate and sub-tropical zones, the state is also unique in that it is a long and narrow peninsula, surrounded on three sides by warm water, creating a dynamic environment. The impacts of climate change, such as sea-level rise and severe storms, threaten the state’s unique biodiversity—yet managers are unsure how species will respond to these changes, which makes planning for the future difficult. In order to identify the impacts of climate change on Florida’s plants and wildlife, researchers developed regional climate scenarios identifying how temperature and precipitation patterns...

The U.S. Geological Survey Dakota Water Science Center, in cooperation with the Federal Highway Administration, analyzed annual peak-flow data to determine if trends are present and provide attribution of trends where possible. Work for the national trend attributions for nonstationary annual peak-flow records was broken into seven regions that are loosely based off of two-digit hydrologic unit watershed boundaries. Each of the regions made attributions for nonstationary annual peak-flow records using both monotonic trends and change point for 50 (1966-2015) and 75 (1941-2015) year trends. Each child page contains four supporting comma separated values (csv) files (50-year monotonic, 75-year monotonic, 50-year change...

Attributions for nonstationary peak streamflow records in the Southeast region, 1941-2015 and 1966-2015, and supporting information

Southeast (SE) Region. The U.S. Geological Survey Dakota Water Science Center, in cooperation with the Federal Highway Administration, is analyzing annual peak-flow data to determine if trends are present and provide attribution of trends where possible. This dataset contains four core comma separated values (csv) files (50-year monotonic, 75-year monotonic, 50-year change point, and 75-change point). Each of the four core csv files includes the USGS gage identifier, various statistical values, primary and secondary attribution, level of evidence, and comments/citations. The comments/citations column should include any sources, in addition to the statistical values in the csv, that were needed to decide on the correct...

Digital Elevation Model (DEM) at 50 m resolution for the Everglades Depth Estimation Network (EDEN)

Since its inception, the Everglades Depth Estimation Network (EDEN) has used the High Accuracy Elevation Dataset (HAED) digital elevation model (DEM) to provide scientists and managers with continuous water depth surfaces, derived from interpolated water stage, on a 400 X 400 meter grid. A new, high resolution LiDAR-based DEM is available through a collaboration between Everglades National Park (ENP) and the U.S. Geological Survey (USGS) 3D Elevation Program (3DEP). This new DEM covers the southern part of the EDEN extent, including a large area of ENP and a portion of southeast Big Cypress National Preserve. It is provided at a resolution of 0.5 meters but contains data voids in surface water areas where the LiDAR...
