Some ideas about layout.
<COMPANY>/
<COMPONENT>/ - fixed layout with all optional folders (extept src/)
doc/
src/
shared/ - external libraries used by this component
examples/
For release planning it would be also good to introduce branches/tags there
to release each of the components separately:
trunk/MyOpenSource/
HEC/
RAS/ <---------- current development version of RAS
src/
examples/
...
USGS/
MODFLOW/
...
CUASHI/
WaterOneFlow/

tags/MyOpenSource/
HEC/
RAS-1.0/ <------ SVN copy of the trunk released on DD.MM.YYYY

RAS-2.0/
