Introduction

This page collects information about the application of the Representative Elementary Watershed model.

Versions

Installation

THREW

Macintosh / linux

An easy way to install on mac and linux is by creating first static libraries for the solver and then linking those in the application. The advantage of this is that you don't need to recompile the solver each time you make changes to the model, which is quicker. Compiling it this way involves the following steps:

• download the cvode solver from the cvode/sundials website At the time of writing that is cvode-2.5.0.tar.gz

• decompress cvode-2.5.0.tar.gz, and add the directory /include/threw/ from the threw model to cvode-2.5.0/include. Replace the file cvode-2.5.0/src/cvode/cvode.c with the one included in the THREW model.

• Compile the solver with the changes we just made. This can be done with the following commands from within the cvode-2.5.0 directory:

    ./configure
    ./make

• copy the static libraries, which reside in a hidden directory

    cp src/cvode/.libs/libsundials_cvode.a ./
    cp src/nvec_ser/.libs/libsundials_nvecserial.a ./

• then copy both files (libsundials_cvode.a and libsundials_nvecserial.a) into the src directory of the THREW model.

• now you should be able to compile the threw model with the following command:

    gcc -pipe threw_closure.c threw_error.c threw_f.c threw_init.c threw_io.c threw_utility.c threw2.c -o threw2 \
    -L. -lsundials_cvode -lsundials_nvecserial -I../include
