Algae Developments

HR Wallingford has made developments to the Algae code (i.e. the Seaweed code) for TELEMAC 2D. These developments have made on the branch called “plaice”.

The developments relate to the positioning of the initial Algae particles and apply to any drogues. Drogues can be defined using a polygon file and in the geometry file as well as being defined in the subroutine USER_FLOT. Relevant subroutines include CONDIN_DROGUES and the subroutines in the module DROGUES. The particles can be output to a binary (PCL) file which can be read by BlueKenue. The output file is written by the subroutine UTIMP_DROGUES.

Algae classes can be defined and different Algae properties can be defined for each class. The Algae can start to move after a specified time has elapsed. Alternatively Algae can start to move after being dislodged after a critical bed wave orbital velocity has been reached. Relative subroutines for the Algae movement are DERIVE and the subroutines in the module ALGAE_TRANSP.

The code has been merged with the most recent Trunk code and, unless any issues arise with other developers, we will soon formally commit the new code to the trunk.
