xs_area: Cross-Sectional area

In brownhr/xsarea: Tools for Cross-Section Hydrological Data

Cross-Sectional area

Description

Calculate area of a cross-section using the trapezoidal rule for integration. By default, uses the columns "TAPE" for measurement across xs, "InvertRod" for depth relative to y = 0, and "Bankful" for baseline measurement.

Usage

xs_area(data, tape, depth, baseline, sum_area = TRUE)

Arguments

data	A data.frame of cross-section data
tape	A column from data or a numeric vector of tape readings ("x coordinates").
depth	A column from data or a numeric vector of rod readings ("y coordinates").
baseline	A column from data or vector representing bankfull level.
sum_area	A logical (default TRUE) indicating whether to return a single summary of the trapezoidal area or a tibble indicating the area at each section.

Value

A Double of the cross-sectional area compared to a baseline
