| Describe input parameters
|
The input variables used for the Dynamic Wave method of routing flow in channels are defined as follows. These inputs must be provided as grids:
- flow_codes = D8 flow codes (Jenson convention)
(NE,E,SE,S,SW,W,NW,N) → (1,2,4,8,16,32,64,128)
- bed_slope = slope of the channel bed or hillslope (m / m)
- Manning_n = Manning roughness parameter (s / m1/3)
- bed_width = bed width for trapezoidal cross-section (m)
- bank_angle = bank angle for trapezoid (deg) (from vertical)
- sinuosity = channel sinuosity (unitless) (along-channel / straight length)
- init_depth = initial water depth (m) (See Notes below)
These inputs can be provided as scalars or grids:
* sinuosity = channel sinuosity (m/m) (along-channel / straight length)
* init_depth = initial water depth (m) (See HTML help)
Grids must be saved in binary files with no header. All variables should be stored as 4-byte, floating-point numbers (IEEE standard) except flow codes, which are unsigned, 1-byte integers.
The behavior of this component is controlled with a configuration (CFG) file, which may point to other files that contain input data. Here is a sample configuration (CFG) file for this component:
