Roles of Models in Watershed Analysis

  • Research dynamics affecting

water conditions

  • Predict (estimate) water

conditions (in un-monitored locations in space or time)

  • Inform policy/investment

decisions w.r.t. restoration, conservation, TMDLs, etc.

– AND Monitoring Strategy!

  • Integrated Research
  • Standardized Data
  • Automated Analysis
  • Open-source collaborative

development

– i.e. standardized component models

  • Dynamic user-feedback

Coordinated Adaptive Watershed Analysis

A Problem with Scale

  • Low-rez Basin-wide vs. high-rez site/micro-shed analysis
  • Computational limitations
  • Data resolution / uncertainty
  • Know-how

Spatial Datasets Overlaid & Aggregated at Various Scales

  • Types of data:

– Anything with a spatial reference – Environmental conditions:

  • Topography
  • Landcover
  • Soils
  • Geology
  • Climate
  • Point sources

– Monitoring data – Model outputs

  • Aggregation scales:

– Drainage area

  • Upstream drainage area
  • Reach lateral drainage

area

  • Confluence lateral

drainage area

  • Upstream distance

interval lateral drainage area

– Riparian Zone – Hillslope Intervals – Left/Right Bank

~ 200m Reach Lateral Drainage Areas arranged by Upstream Junction

  • Relatable to confluence-scale

data / models, i.e.

  • EPA SPARROW
  • NHD Plus, etc.

Next Steps

  • Continue packaging StreamHiker tools as stand-alone package

hosted on GitHub

  • Incorporate into ANSDU data management system (develop

interactive mapping and data access tools)

  • Statistical models

– i.e. Stream temperature – Decay functions w.r.t. upstream distance – Cascading downstream models (i.e. SPARROW)

  • Facilitate usage/get feedback from project partners
