Source code, license, example input and visualization files for beta-LTRANS-ADCIRC, a particle tracking model that runs with ADCIRC circulation model prediction.

<p>From&nbsp;http://northweb.hpl.umces.edu/LTRANS.htm</p>

<p><strong>beta-LTRANS-ADCIRC</strong> is based on the&nbsp;<strong>Larval TRANSport Lagrangian model (<a href=\"http://northweb.hpl.umces.edu/LTRANS.htm\">LTRANS v.2b</a>),</strong> an off-line particle-tracking model that runs with the stored predictions of a 3D hydrodynamic model. In this case, LTRANS v.2b has been substantially modified to be able to run with the finite-element circulation predictions of <a href=\"http://adcirc.org/\">ADCIRC</a>. Although LTRANS was built to simulate oyster larvae, it can easily be adapted to simulate passive particles and other planktonic organisms. LTRANS v.2 is written in Fortran 90 and is designed to track the trajectories of particles in three dimensions. It includes a 4th order Runge-Kutta scheme for particle advection and a random displacement model for vertical turbulent particle motion. Reflective boundary conditions, larval behavior, and settlement routines are also included. A brief description of the beta-LTRANS-ADCIRC particle-tracking model can be found <a href=\"http://northweb.hpl.umces.edu/LTRANS/LTRANS_description.pdf\">here</a>&nbsp;(68 KB .pdf). For more information on LTRANS, please see the LTRANS web page. and the application of LTRANS to oyster larvae transport, see <a href=\"http://northweb.hpl.umces.edu/research/Oyster_larvae_DNR.htm\">a summary web page with animations, </a>the publications<a href=\"http://northweb.hpl.umces.edu/LTRANS-ADCIRC.htm#Northetal2008\"> North et al.

<p><strong>External Dependencies and Programs</strong>.&nbsp;beta-LTRANS-ADCIRC requires&nbsp;NetCDF libraries&nbsp;and uses the following programs to calculate random numbers (Mersenne Twister) and fit tension splines (TSPACK). Because beta-LTRANS-ADCIRC reads-in ADCIRC-generated NetCDF (.nc) files, it requires that the appropriate NetCDF libraries be installed on your computer (see files and links below). Also, please note that although the Mersenne Twister and TSPACK programs are included in the beta-LTRANS-ADCIRC in the Random_module.f90 and Tension_module.f90, respectively, they do not share the same license file as beta-LTRANS-ADCIRC Please review and respect their permissions (links and instructions provided below).</p>
