ABSTRACT:

The HydroDS tasks required to be executed to get complete UEB model inputs for an example watershed are given in the Python file “HydroDS_UEB_Setup”. This file calls functions from the other file, "hydrods_python_client" that has declarations for data service functions available from HydroDS.

To run the workflow for a different watershed in the Western US, modify the coordinates of the watershed boundary, outlet location, the start and end time of model period, and the spatial reference (projection) information in the form of EPSG Code (http://spatialreference.org/ref/epsg/). The commands in the workflow script can also be called interactively from any Python command line, or from a user application that uses incorporates the Python Client Library.

For watersheds outside of the Western US, but in the CONUS, you need to upload your own DEM. The services are currently limited to the US.
You need to have a HydroDS account to use these services.

These scripts are for the following paper

ABSTRACT:

This document provides brief descriptions of HydroDS, a data processing web-based service for distributed/gridded hydrological models. HydroDS enables the generation of distributed (gridded) data for variables commonly used in hydrologic models in three widely used file formats: GeoTiff raster, shapefile, and multi-dimensional NetCDF. HydroDS provides functions for watershed delineation, terrain processing, estimation of canopy variables, and retrieval of climate data. The functions can be used independently or chained together to form a workflow that performs a set of related tasks.
