add reach properties from NHDPlus data #22

Closed saubhagya-gatech closed 2 years ago

saubhagya-gatech commented 2 years ago

provide a way to include additional useful data from NHDPlus as reach properties.

This includes:

catchments
NHDPlusFlowVAA table
NHDPlusEromma table

Currently only select properties are supported from these tables. This can be easily expanded by adding more alias names in the dictionary of alias names and codes provided in manager_nhd.py.

saubhagya-gatech commented 2 years ago

Currently supported properties: 'StreamOrder', 'StreamLevel', 'HydrologicSequence', 'DivergenceCode', 'CatchmentAreaSqKm', 'TotalDrainageAreaSqKm',' MeanAnnualFlow', 'catchments', 'StreamOrder', 'HydrologicSequence', 'catchments'

Example usage:

 _, reaches = watershed_workflow.get_reaches(sources['hydrography'], huc, 
                                      watershed.exterior().bounds, crs, crs, 
                                      properties=['MeanAnnualFlow','catchments','StreamOrder','HydrologicSequence', 'MeanAnnualFlowGaugeAdj'])
