In this lab, we are using a theoretical ri … In this lab, we are using a theoretical river basin of ~1990 km<sup>2</sup>, with 1200m of relief and a river length of ~100 km. All parameters that are shown by default once the HydroTrend model is loaded are based on a present-day, temperate climate.</br>Whereas these runs are not meant to be specific, we are using parameters that are realistic for the Waiapaoa River in New Zealand. The Waiapaoa River, located on North Island, receives high rain and has erodible soils, so the river sediment loads are exceptionally high. It has been called the 'dirtiest small river in the world'. A more detailed description of applying HydroTrend to the Waipaoa basin has been published in ''Water Resources Research'': http://dx.doi.org/10.1029/2006WR005570. To learn more about HydroTrend and its approach to sediment supply modeling, download the presentation listed below.</br></br><p>This lab can be run on either the <em>lab</em> (for educators) or <em>jupyter</em> (for general use) instance of the OpenEarthscape JupyterHub: just click one of the links under the <strong>Run online using</strong> heading at the top of this page, then run the notebook in the "CSDMS" kernel.</p></br></br><p>If you don't already have a JupyterHub account, follow the instructions to sign up at https://csdms.colorado.edu/wiki/JupyterHub.

In this lab, we use the HydroTrend model to investigate river sediment supply to the ocean by exploring the effects of climate change on river fluxes. We also look at the effect of humans on rivers: the building of a reservoir. +

Instead of downloading the lab Notebook an … Instead of downloading the lab Notebook and running it locally, or running it through the CSDMS JupyterHub, you can also run it on Binder. Follow these steps:</br><br></br>>> Open a new browser window and go to: https://pymt.readthedocs.io/en/latest/examples.html</br></br>>> You will see that there are several example models. In this lab we will select the HydroTrend model.</br></br>>> Click on the "Launch Binder" button to run this lab.</br></br>Note that Binder is a free and popular service for running Jupyter Notebooks, so it can be slow to load at times.</br></br>The HydroTrend model is run with the Python Modeling Tool, ''pymt''. Learn more about ''pymt'' at: https://pymt.readthedocs.io.</br></br>For a similar lab done with a spreadsheet, download and try: https://csdms.colorado.edu/csdms_wiki/images/RiverFluxtoOceanSpreadsheetLab.zip.colorado.edu/csdms_wiki/images/RiverFluxtoOceanSpreadsheetLab.zip. +
If run locally, this lab requires the installtion of pymt; see https://pymt.readthedocs.io/en/latest/quickstart.html for instructions. This lab runs on Linux and macOS. +
