The default value is Manning’s n. Depth/Ripple Height Factor Limit == [ {10} | (Optional. Only used if bed resistance values are set to CHEZY) Sets an upper limit on the ratio of the water depth over the ripple height in the formula for calculating Chezy values based on water depth. The value must be greater than 1/12, and if less than 1/12 is set to the default value of 10. Read Materials File == (Optional. Presently only available for MANNING N based bed resistance values.
Reads a text file containing Manning’s n values for different materials (land-use types). The file can contain comments using the “#” and/or “!” delimiters. A maximum of forty (40) materials is allowed – this can be increased upon request. In earlier versions the maximum was twenty (20). The first number is the Mat (Material ID) number, which must be an integer. The second value is the Manning’s n value (see example below). Optionally, as of Build 2005-05-AN, the third and fourth numbers set the initial and continuing loss rates in mm and mm/h if using Read MI SA Rainfall (see example below). It is highly recommended that this approach be used, especially for model calibration. Editing this file is far easier than making changes to Manning’s n values in GIS layer(s). The material values may also be used to define bed resistance values across 1D XZ cross-sections (see Section 3.13.5.2). The file format is shown in the example below. See Set, Read MI and Read MID with the MAT option for setting the Mat values.
! First value is the Mat value ! Second is the Manning's n value ! Maximum of 20 different materials 1, 0.03 ! waterways 2, 0.08 ! river banks 11, 0.06 ! grazing land 12, 0.04 ! parks and gardens 13, 0.15 ! sugar cane 14, 0.12 ! natural forest 15, 0.02 ! roads To include the initial loss (mm) and the continuing loss rate (mm/h) optionally enter a third and fourth value as shown below. If an IL is specified, a CL must also be specified otherwise and ERROR occurs. Both can be omitted, in which case, they are both set to zero. 1, 0.03 ! waterways 2, 0.08, 20, 2 ! river banks 11, 0.06, 20, 2 ! grazing land 12, 0.04, 5, 1.5 ! parks and gardens 13, 0.15, 10, 2 ! sugar cane 14, 0.12, 30, 2.5 ! natural forest 15, 0.02, 2, 0 ! roads
(Optional) Warning: This command overwrites any previous “Bed Resistance Values” command by setting bed resistance values to CHEZY. Sets the number of timesteps between recalculation of Chezy values based on the ripple height. The default value of zero indicates Chezy values are not recalculated (ie. remain constant throughout the simulation). Yüklə 4,62 Mb. Dostları ilə paylaş:
