Description Usage Arguments Value
View source: R/AASHGS_Execute.R
This function executes the at-a-station hydraulic geometry simulator, which is a method of determining weighted usable area. For more information about the theoretical component of this model see: McParland et al. (2016). At-a-station hydrualic geometry simulator. River Res. Applic. 32: 399 - 410. This function requires that the 'birk' package is loaded in your directory.
1 2 | AASHGS_Execute(S, wb, db, db_max, max_Q, d_curve, v_curve,
s_curve = NULL, D84, gsd = NULL)
|
S |
channel gradient (m/m) |
wb |
reach averaged bankfull width (m). |
db |
reach averaged bankfull depth (m). |
db_max |
Defaults to NULL. reach averaged maximum bankfull depth (m). Specifying db_max is preferred. |
max_Q |
maximum discharge (m3/s) to simualted WUA for. Defaults to simulated bankfull dsicharge. |
d_curve |
A dataframe of depth suitability curves with four columns as follows: column 1: "species" - This identified species (eg "species"); column 2: "life_stage" - This identifies life stage (eg "fry"); column 3: "depth" (m); column 4: "suit" (0 - 1) |
v_curve |
A dataframe of velocity suitability curves with four columns as follows: column 1: "species" - This identified species (eg "species"); column 2: "life_stage" - This identifies life stage (eg "fry"); column 3: "velocity" (m/s); column 4: "suit" (0 - 1) |
s_curve |
Defaults to NULL> A dataframe of substrate suitability curves with five columns as follows: column 1: "species" - This identified species (eg "species"); column 2: "life_stage" - This identifies life stage (eg "fry"); column 3: "lower" (mm) - This identifies the lower limit of each class; column 4: "upper" (mm) - This identifies the upper limit of each class; column 5: "suit" (0 - 1) |
D84 |
grain size (mm) |
gsd |
Defaults to NULL. A dataframe of the grain size distribution with one column: individual grain sizes (mm). Intended for use with output of the Find_D84 function. |
