GW Recharge

Title  GW Recharge

Summary

Calculates ground water recharge in a user-defined area for various scenarios: baseline: a best-guess of ground water recharge rates based upon land cover (from a dominant condition analysis of the Cropland Data Layer for the years 2010 - 2013), hydrologic soil group (from SSURGO), and (optionally) slope class (<2%, 2-5%, >5%) within the user-defined area. baseline_change: a change in ground water recharge from a baseline condition (as defined above), and a user specified condition: a land cover or BMP, a hydrologic soil group (optional), and slope class (optional) dual_scenario: a difference in ground water recharge from two user-specified conditions as defined above.


Usage

Syntax

Parameter Explanation
runid

A unique identifier for the scenario. '#' will create an auto-generated ID.
coords

Polygon coordinates in lat./lon.
scenario

The recharge scenario type. baseline -

include_slope

Boolean indicating whether slope should be referenced in calculations of recharge.
model_tile_drainage

(optional) Boolean indicating whether tile drainage should be referenced in calculations of recharge. Note: tile drainage will only be applied to agricultural land covers.
user_luse

(optional) In a baseline change or dual scenario simulation, this refers to the SWAT-formatted land use code(s) to be simulated. In a baseline change simulation, a single string should be provided. For example, 'FRSD' will simulate recharge in the user-defined area if the land cover was all deciduos forest. In a dual scenario simulation, a value of FRSD,CORN will calculate differences in recharge if the user defined area was converted from all FRSD to all CORN.
user_hsg

(optional) In a baseline change or dual scenario simulation, this refers to the hydrologic soil group (A,B,C, or D) to be simulated. The format and function is the same as the user_luse input.
user_slope

(optional) In a baseline change or dual scenario simulation, this refers to the slope class (1,2, or 3) to be simulated. The format and function is the same as the user_luse input. A slope class of 1 refers to lands where slope is < 2%, class of 2 refers to slopes of 2-5%, and class 3 refers to slope > 5%.
