ABSTRACT:

This resource contains data that shows the different local parks in the state of Utah.

ABSTRACT:

This HydroShare resource contains all datasets, reproducible workflows, and Python/Jupyter Notebook scripts used in the manuscript “How Well Do U.S. National Water Model Short-Range Forecasts Predict Flood Event Timing and Magnitude?” (Maghami et al., 2025; under revision). The study evaluates the U.S. National Water Model (NWM) v2.1 short-range (0–18 hr) forecasts for 306 USGS stream gauges across 16 study areas in the continental United States, covering flood events occurring between April 2021 and September 2023.

The resource provides a complete end-to-end reproducible pipeline, including:

- identification and selection of USGS gauges and flood peaks,
- watershed delineation and integration of land-cover, climate-zone, regulation status, stream order, and drainage-area attributes,
- gauge-to-COMID matching using NHDPlus V2.1,
- extraction of short-range NWM forecasts and return-period estimates via the NWM BigQuery API,
- quality-control screening of USGS observations,
- multi-event flood selection using consistent peak-based criteria, and
- computation of evaluation metrics (scaled KGE, time-to-peak bias, peak-discharge ratio, and flow-volume ratio) across 18 lead times.

The workflows also generate the hydrographs, performance plots, and stratified analyses used in the manuscript (by return period, climate zone, imperviousness, stream order, and regulation status). The notebooks (JN1–JN10) and directory structure are fully documented to support transparency and reproducibility.

A README file is included with instructions for running each workflow, required software environments, and detailed descriptions of all input and output files. This resource will be made public upon manuscript acceptance and assigned a DOI to support citation, reproducibility, and long-term accessibility.

ABSTRACT:

Dummy Resource to be used with the NWM Mobile App

ABSTRACT:

streams2: Stream Order 4 and higher in the United States considered by the National Water Model with data fields like: station_id, streamOrder, and ShapeLength. (3.6 thousand total)
streams3: All streams in the United States considered by the National Water Model with data fields like: station_id, streamOrder, and ShapeLength. (2.7 million total)
midpoint: All streams (not polylines but points) in the United States (converted to Midpoints using ArcGIS Pro) considered by the National Water Model with data fields like: station_id, streamOrder, and ShapeLength. (2.7 million total)

ABSTRACT:

Resource of datasets used for the development of the National Water Model Mobile App.

ABSTRACT:

This resource contains streams of the US considered in the National Water Model as midpoints to be used in the mobile NWM App viewer for Android and iOS that's currently under development. It provides a shapefile with the streams as midpoints, a csv with the stream ID and their respective latitude and longitude values. It also provides the same information in database formats. One of the database files do not include an ID.
Again, this data is for testing purposes. More data will be potentially added in the future.

ABSTRACT:

This resource was created for CE 534 Homework 8 and as a demonstration of using the HS RDF Python Client for HydroShare. Once I completed all of the steps in this notebook, I will have a fully populated HydroShare Resource.
