ABSTRACT:

This includes an example for UEBGrid model simulation. For UEBGrid code details, please go to https://bitbucket.org/dtarb/ueb/src. For example in LangtangKhola watershed, please go to http://hydrology.usu.edu/snow/uebgrid/Data.rar

ABSTRACT:

This resource includes the simulation and observation discharge data and corresponding data analysis code for Dolores River watershed. The observation data is from USGS gage station. The basin discharge simulation was created by coupling Utah Energy Balance snowmelt model and Sacramento Soil Moisture Accounting (SAC-SMA) runoff model.
This resource is aimed to demonstrate how to use the Jupyter Notebook to repeat the data analysis process. To test please use the link to access the app (https://jupyter.cuahsi.org/hub/login)

ABSTRACT:

This resource stores the Sciunit object to help repeat the model input preparation and model execution for basin discharge simulation in Dolores River watershed using the Sacramento Soil Moisture Accounting (SAC-SMA) runoff model. The rain plus melt input for SAC-SMA model was created from the Utah Energy Balance snowmelt model output.

This Sciunit object is a container that enables reproduction of the modeling process without software installation. The Jupyter Notebook app in HydroShare can help execute the Sciunit object.

ABSTRACT:

This resource collects all the data and code to reproduce the hydrologic modeling research, which coupled Utah Energy Balance (UEB) snowmelt model with the Sacramento Soil Moisture Accounting (SAC-SMA) run-off model to simulate the basin snowmelt process and discharge for the Dolores River watershed. This research is aimed to evaluate the UEB model performance using the Daymet input for water supply forecast in the study watershed. It is also aimed to demonstrate how to use different web based apps and software to support reproducible hydrologic modeling research.

This resource collects 3 resources:
resource 1: includes the model input/output files for UEB model simulation which was created using the UEB web application.
resource 2: includes the Sciunit object to help reproduce rain plus melt input processing (based on UEB model output) and SAC-SMA model simulation process.
resource 3: includes the observational data, model output files, and python analysis code for model results analysis.

ABSTRACT:

This is the model simulation of snow water equivalent in Logan River watershed from 2008 to 2009. The model used is the Utah Energy Balance model which is a snowmelt model. The simulation result is used as the input data for SAC-SMA model to simulate the stream flow of the watershed. asdfasd

This is the web app that enables OPeNDAP service for the Multidimensional space-time data resources in HydroShare. The OPeNDAP service is available only for the "Public" Multidimensional space-time data resource. Due to current Hyrax deployment limitations this does not work for large NetCDF files. Exact upper limit unknown, but has been tested up to 200 MB successfully.
