Model Input

This section contains the input data necessary for watershed model simulation, from watershed condition, load information to management measurements. All data are aggregated either to land segment or land-river segments, and some of them are further differentiated by land use. Since Phase 5 model uses its own naming system, before downloadloading any data sets, you will need to download either landnames.xls, rivernames.xls, or landuse_definations.xls to figure out which data files are for your geographical region of interest.

Atmospheric Deposition

The MS Excel worksheets provided summarize annual and monthly average atmospheric deposition for each model land segment (i.e. county) for the period of 1984-2005.

BMP

BMP Pounds - The comma separated values files within this zip directory contain BMP data for the Phase 5.3 Watershed Model Calibration for the years 1985, 1987, 1992, 1997, 2002, and 2005. Reductions in pounds are displayed for each combination of land-river segment, BMP, land use type, and constituent (ex. Total Nitrogen). Please note that the 1985 and 1987 files are empty.

The data is organized as follows:
River segment, Land Segment, BMP Shortname, Landuse_Type, Constituent, Pounds

BMP Acres - The comma separated values files within this zip directory contain BMP data for the Phase 5.3 Watershed Model Calibration for the years 1985, 1987, 1992, 1997, 2002, and 2005. Acres of each BMP are displayed for each combination of land-river segment, BMP, land use type, and constituent (ex. Total Nitrogen).

The data is organized as follows:
River segment, Land Segment, BMP Shortname, Landuse_Type, Acres

Crop Data

Maximum Uptake - The comma separated values files within this zip directory contain maximum uptake data for the Phase 5.3 Watershed Model Calibration for the years 1985, 1987, 1992, 1997, 2002, and 2005. Maximum uptake in pounds per year is listed for each Land Segment, Land use, and constituent (Nitrogen or Phosphorous).

The data is organized as follows:
Land Segment, Land Use, Constituent(N or P), Maximum Uptake(lbs/yr)

Uptake Curve - The comma separated values files within this zip directory contain uptake curve data for the Phase 5.3 Watershed Model Calibration for the years 1985, 1987, 1992, 1997, 2002, and 2005. The uptake curve is displayed as a decimal fraction for each Land Segment, Land use, constituent (Nitrogen or Phosphorous), and month.

The data is organized as follows:
Land Segment, Land Use, Constituent (N or P), Uptake fraction by month

Uptake Target - The comma separated values files within this zip directory contain uptake target data for the Phase 5.3 Watershed Model Calibration. The uptake target is displayed in lbs/acre/yr for each Land Segment, Land use, constituent (Nitrogen or Phosphorous).

Diversion

These are water taken from a river or reservoir for water supply or irrigation.

EOF Targets

These are calibration targets for loadings that transfer from the land to the river segments throughout the watershed in pounds per acre per year. EOF Target files are separated by nutrient (TN or TP), land use, and land segment.

Land Use

The comma separated values files within this zip directory contain land use data for the Phase 5.3 Watershed Model Calibration for the years 1985, 1987, 1992, 1997, 2002, and 2005. Acres of each land use are displayed by land-river segment.

The data is organized as follows:
River Segment, Land Segment, Land Use (Acres)

NPS Nutrients

Fertilizer - The comma separated values files within this zip directory contain input loads from fertilizer to the Phase 5.3 Watershed Model Calibration for the years 1985, 1987, 1992, 1997, 2002, and 2005. The loads of different species (organic nitrogen and phosphorous, nitrate, ammonia, and phosphate) are displayed by land segment and land-use.

The data is organized as follows:
Land Segment, Land Use, Species (nh3n, orgp etc.), Load (lbs/acre) by month

Manure - The comma separated values files within this zip directory contain input loads from manure to the Phase 5.3 Watershed Model Calibration for the years 1985, 1987, 1992, 1997, 2002, and 2005. The loads of different species are displayed by land segment and land-use.

The data is organized as follows:
Land Segment, Land Use, Species (nh3n, orgp etc.), Load (lbs/acre) by month

Legumes - The comma separated values files within this zip directory contain input loads from legumes to the Phase 5.3 Watershed Model Calibration for the years 1985, 1987, 1992, 1997, 2002, and 2005. The loads of different species are displayed by land segment and land-use.

The data is organized as follows:
Land Segment, Land Use, Species (nh3n, orgp etc.), Load (lbs/acre) by month

Point Source

The point source file contains point source flow and nutrient loads daily by land-river segment for point sources and CSO’s (combined sewer overflows). The files are formatted as comma separated values files.

Septic

The comma separated values file septic_p53cal_allyears.csv contains estimated septic load for each land-river segment in pounds per day.

Soils

These files contain percentage of various types of soils present in each land segment (by FIPS code only), the accuracy of the data, and the percentage of sand, silt, clay, and organic matter of each county's soil. There is also a file containing information pertaining to the soil property analysis, the soil texture properties, and figures displaying data taken from the STATSGO database.
