Irrigated acreage used in TOPNET #7

Open ChristinaB opened 6 years ago

ChristinaB commented 6 years ago

Following is a description (and any needed clarifications) of irrigated acreage used in TOPNET, for as much of the MODFLOW domain as overlaps with TOPNET domain.

ChristinaB commented 6 years ago

Irrigated acreage used in Topnet is controlled in basinpars.txt, which is the primary parameter input file for drainage-based parameters - e.g., for WRIA1 model extent there 172 drainages and 172 rows of parameters in basinpars.

Format_basinpars.pdf contains all of the metadata for the basinpars file. (We have a file like this for every Topnet file - see the folder: ModelFilesDescriptions

In the attached Excel spreadsheet, I imported the basinpars text file and extracted Bertrand Creek and Fishtrap as an example, deleting all parameters except those related to irrigation. Note that direct area is in mm2, converted here manually to km2. The irrigated fraction of Bertrand Creek area (95 km2 ) is 37%. Of that 37% irrigation, 38% is the sprinker fraction of irrigation (with the remaining 62% drip irrigation). The combined weighted irrigation efficiency for Bertrand is 75%. Note 1: Bertrand is CatchID 87 and DrainageID 6. These two numbers should not be confused! (it's a team effort to keep these numbers straight, so always double check) basinparsWRIA1.xlsx Note 2. This version of basinpars is the model input for the Lower Nooksack Water Budget 2012 project.
