Couple of people have asked about this being implemented now (like CAEASR-Lisflood reach mode)
Would be nice to have implemented.
Summary
Reach model also requires a DEM in the same format as the catchment model/mode. Water will exit from any edge of the DEM, but as per catchment mode, not be routed in NODATA cells.
Reach mode requires an additional file that contains the water and sediment inputs into the catchment. The format of the file is a standard plain text/ascii file with the following layout:
time step
water discharge
blank
blank
blank
d1 grain vol
d2 grain vol etc
d3
d4
d5
d6
d7
d8
d9
1
3.62

The file format is in the same format as the catchment output file catchment.dat (Hence the blank columns, these do not need to contain data when used as input.)
Parameter file additions
[x] The parameter file will need modifying to accept the x y coords for all/any input points, and a routine needed to input these points into the reach_mode function.
Test Case
Use the same test case for comparability between the Win model and this one.
Reach mode: Modelling the River Severn nr. Caersws, U.K.
This example is for a c.2km by 2km section of the River Teifi, immediately downstream from Lampeter, Wales. The DEM is at 10m resolution and created from downgraded LiDAR data. To run this example, download the relevant files which include the main program file (Caesar 5.1.exe) and the sample data files teifi.zip and swale.zip. Unzip and place them all in one directory.
The three files to be used for the Teifi example are whole9.txt (the DEM file) input2.txt the water and sediment input data file and teifi1.xml - the configuration file.
