<p>This lab would work best with an introduction to cratering as a geomorphic process, and the importance of cratering as an age constraint for planetary surfaces. There is enough information that students with limited coding experience could read and run the notebook independently, as there is only one input for an initial number of craters. Students experienced with coding will be able to change parameters and explore the effects. There are several short, open-ended questions scattered throughout that could be used as a problem set or points of discussion.</p>

Here is a helpful link - https://www.usgs.gov/centers/sa-water/science/flood-frequency-information?qt-science_center_objects=0#qt-science_center_objects
You could include requirements that students check their results for the given rivers (Fishing Creek, Tar River, Ellerbe Creek, and Roanoke River) to the USGS calculations for an extended assignment.
I have adapted a lab similar to this one by SERC (https://serc.carleton.edu/hydromodules/steps/168500.html) from T. Perron using excel to analyze flood frequency of a river into python. It would be easy enough to include more background on Wollman & Miller, geomorphic work, the characterstic flood, extreme value analyses, etc dependent on your course interest and focus.
Please visit https://github.com/ale37911/CSDMS_Labs/tree/main/Flood_Freq for associated files (data and instructor Notebook).

>> You will see that there are several example models. In this lab we will select the HydroTrend model.
>> Click on the "Launch Binder" button to run this lab.
Note that Binder is a free and popular service for running Jupyter Notebooks, so it can be slow to load at times.
The HydroTrend model is run with the Python Modeling Tool, ''pymt''. Learn more about ''pymt'' at: https://pymt.readthedocs.io. +

<p>Note that the data files required for the lab have been uploaded to the CSDMS JupyterHub and placed in the directory <code>/data/TCM_data_CSDMS_Ex</code>; the Notebook will need to be updated with this path. Also note the Notebook uses about 5 GB of memory, so it's possible to run out of memory if many people are using the JupyterHub simultaneously.</p> +

River discharge data for many US rivers is available from the USGS WaterWatch website:
http://waterwatch.usgs.gov/?m=real&r=co.
River stage data is typically measured by keeping track of the water surface height over time, i.e. stage, and this needs to be converted to discharge through a stage-discharge relationship.
Tabular data like these, with a combination of dates, name and data quality strings, and numbers are best handled by spreadsheets where entries such as dates and times are in some useful format. In Python the Python Data Analysis Library (a.k.a. Pandas) is really useful for this purpose.
We use one discharge data file downloaded for the USGS station at Kremmling, CO, for the Upper Colorado.

Start at the top by reading each block of text and sequentially running each code block (shift - enter OR got to the Cell pulldown menu at the top and choose Run Cells).
If you just change one code block and rerun only that code block, only the parts of the code in that code block will be updated. (E.g. if you change parameters but don't reset the code blocks that initialize run time or topography, then these values will not be reset.)<br>

In this lab we will select the Frost number GEO component as the driving model, we will combine it with temperature data from the CMIP5 climate simulations.
If you have done the previous labs, you now are familiar with the approach of the Air Frost number, it uses the mean annual air temperature of a location (MAAT), as well as the yearly temperature amplitude. In the Air Frost parametrization the mean monthly temperature of the warmest month and coldest month set that amplitude. In the model coupling here we have assumed the warmest month is July and the coldest month is January. The 'degree thawing days' are above 0 C, the 'degree freezing days' are below 0 C. To arrive at the cumulative freezing degree days and thawing degree days, the annual temperature curve is approximated by a cosine as defined by the warmest and coldest months, and one can integrate under the cosine curve (see also in Frost number presentation). The CMIP component is a 'data component' processed from the CRU-NCEP Climate Model Intercomparison Project - 5, also called CMIP 5. Data presented include the mean annual temperature for each gridcell, mean July temperature and mean January temperature over the period 1902 -2100. This dataset presents the mean of all the CMIP5 models, and the original atmosphere ocean models were run for the representative concentration pathway RCP 8.5. In RCP 8.5, greenhouse gas emissions continue to rise throughout the 21st century.
>> Link the Frost number GEO component with the CMIP component >> In the Frost number component parameters adapt the time to start in 1950, for 150 years. Set the model dimensions to xdim=40 and ydim=30. Make sure you request the frost-number-air output file.
>> Then open up the settings for the CMIP5 data component. Make sure you start reading the data from 1950 onwards. Make sure you match the xdim and ydim with the Frost number grid dimensions. In addition, you will need to specify what region in large PanArctic dataset you do want to read. The CMIP5 data are on a half-degree latitude-longitude grid, so it consist of 720 by 360 grid cells. The upper left corner of the grid is at the international date line. For Alaska, set the column offset as 26, and the row offset as 32. Of course, the climate models keep track of 100's of physical variables; for our simple approximation we only need temperature. So this data component is subsampled to only provide monthly air temperature to other components. In the component here, the data is masked to only comprise the present-day permafrost region. The rest of the grid has 'no data' values.
Download the zip file with your simulation output from the run status window. If you unzip the file you will find your output files, we will use the one called 'frostnumber__air.nc'. You can open this file with Panoply and plot the steady Frost number over 150 years by clicking on the 'create plot' icon
What are typical mean annual temperatures over the North Slope of Alaska in the 1950's?
Do you see much change in the mean annual temperatures at the end of the 21st century?
What does the Frost Number map look like for 1955, and for 2095?
What do these specific Frost numbers imply for the likelihood of permafrost occurrence?
We assume that the disappearance of permafrost (as predicted by the Frost number) indeed means all 3m of soil is thawed.
What would be a rough estimation of the amount of new carbon potentially exposed to the global atmosphere and carbon cycle?
How does that amount compare to the total amount of carbon in the atmosphere? (Hint, see Schuur et al., 2015).
Discuss the factors that would make this first-order estimation problematic?
