2022/06/13 HARP Work Session :VAHydro Model Components Overview

[rburghol]

Weekly accomplishments:

• Proficiency: last week analysts succeeded in eco flows analysis in R and ran hspf 5.3.2 from command line.

• Concepts covered:

  • basic understanding of land seg, river seg, intake, but reinforcement is needed.
  • they know we have a fortran model and python model, but this is theoretical only
  • getting familiar with R
  • hydrology concepts were introduced in last weeks dam exercise, but reinforcement ideal.
  • I introduced concepts of runoff, baseflow and interflow, and HSPF model conceptualization.

• Check-In

  • Where is everyone?
  • Questions?

• The Model:

  • HSPF in general
  • The CBP implementation of HSPF
  • CBP 5/6
  • VAHydro
  • hsp2

• Spatial Data sets.

  • Phase 5 rivers: , land:
  • Phase 6 rivers, land
  • The Python implementation of HSPF, called $hsp^2$
  • We will be running HSPF the cbp implementation of hspf (we will be enabling this to be the same commands for $hsp^2$)
  • hdf5 - the database used by $hsp^2$
  • This will be the single most important skill that we as a group can obtain... and none of us currently possess it (unless one of the analysts are already in the know).
  • installing rhdf5 in R #207
  • Running rhdf5 ...
    • Can we make it work?
    • Currently the example code (below), shows data, but it is indexed with a simple integer, starting at 1.
    • How do we get the timestamp for this? Is there some reference data set that shares the simple integer index values, then as data has the timestamp (i.e, reference to hours, minutes and seconds).
    • Are there hints on the hsp2 issue queue?
    • Can we find community on the rhdf5 library pages?

• Documentation BMPs!

• Running Models, Model Output

  • Running Phase 5.3/6:
  • Install git bash (can be used for both command line server work and git management) https://git-scm.com/download/win
    • You can accept all defaults when installing (you'll probably want the 64-bit version)
  • Do you have an ssh account? Can you log in?

Exercise: IHA implementation

Exercise intent: Define and apply the IHA metrics used in quantifying and managing human streamflow alteration Paper source: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020EF001816

Exercise: For the USGS 02080500 ROANOKE RIVER AT ROANOKE RAPIDS, NC, analyze pre and post dam streamflow using the metrics referenced in the paper above. You'll want to define the metric, and then use the data to quantify pre/post dam. You'll need to select time periods (e.g. paper references +-15 years dam construction, but also removing 5 years near dam construction to prevent filling effects of reservoir). You'll want to consider impacts to base flow periods, as well as storm flows as part of your IHA metrics.

Product: Collaborative R-markdown file that's self contained. Use the markdown file to document what you've done, with the steps from data collection to analysis to (possible) interpretation/presentation of results. You'll want to use plots to tell the story, in addition to text that describes pre/post implications for streamflow. The referenced paper above will be helpful, and also contains original source of IHA descriptions (use this as part of your digging into background material - see the sentence here: We used the IHA approach (Richter et al., 1996) to describe alteration in different facets of the flow regime, as in previous research (Gao et al., 2009; Olden & Poff, 2003).).
