drains: Drain Boundaries at Stanton Crossing and Silver Creek

In USGS-R/wrv: Wood River Valley Groundwater-Flow Model

Description

Polygons used to define the locations of drain boundaries in the model domain. The polygons clip the line segments along the aquifer boundary (see alluvium.extent), and model cells intersecting these clipped-line segments are defined as boundary cells.

Usage

drains

Format

An object of SpatialPolygonsDataFrame class containing a set of 2 Polygons and a data.frame with the following variable:

Name

identifier for the polygon.

cond

drain conductance in square meters per day.

elev

drain threshold elevation in meters above the North American Vertical Datum of 1988 (NAVD 88).

Geographic coordinates are in units of meters, in conformance with the North American Datum of 1983 (NAD 83), and placed in the Idaho Transverse Mercator projection (IDTM).
