Our method is used for the assessment of macrophytes (species, abundance). See: www.midcc.at/kow2010/ . It is used for assessment of macrophytes for the EU Water Framework Directive, as well as for the Joint Danube Surveys of the ICPDR (2001, 2007, 2013). It is applicable to running as well as still waters. At present a new group in the Czech Republic applies it to macrophyte assessment in mountain reservoirs and coal pit lakes as well as to fish pond studies.
Udo Schmidt-Mumm ([email protected]), see ResGate, can also give you some support (he speaks Spanish).

P.S. has been used also in e.g. Senegal, Nepal, and is used in the whole Danube Basin area, Poland, etc.
I made the question in the project page of Jeanette Wyneken (Florida Atlantic University), to verify neonate sea turtle sex ratios in relation to the nest environment.
I sincerely thank you for your time to respond but I apologize to all of you for the confusion. However, the subject of the abundance of macrophytes in the Danube river interests me as well.
Well, if climate warming proceeds for long enough times, even in the Danube we may then greet sea turtles doing their propagation rituals. Classic Music hotspot, emperor castles, AND mating sea turtles will certainly enhance the cultural and touristic value of our city.
