open TELEMAC-MASCARET The mathematically superior suite of solvers

I have some questions about the simulation of an oil spill.

1. Is it possible to simulate instead of an instantaneous release of oil, a constant one (for example a release such as 10000tonnes/day)

2. In the sources file of TELEMAC there are 2 modules that have to do with oilspill (oilspill.f [Goeury] and oil_flot.f). The manual describes the use and manipulation of the oil_flot.f. The oilspill.f module is included in TELEMAC by using oil_flot.f , or is it a separate subroutine? And if so, is there any example of using it?

3. Last one, is it possible to visualize other results of the oil spill simulation, for example the amount (% of released oil) that evaporated etc?

If someone could enlighten me about these questions, I would be thankfull.
