Equation of macrophyte biomass in AQUATOX. It is applicable to streams, lakes and reservoirs. |
| Long text description |
The MACRIV model represents macrophytes by its oxygen equivalent and is used to model diurnal variation in oxygen and nutrient cycle (Park et al., 2003). AQUATOX (Park et al., 2004) models macrophyte biomass depending on light availability, current velocity and temperature. It distinguishes the bryophytes from the other macrophytes and bryophytes are dependent on nutrients. Equation of macrophyte : biomass in Aquatox dBiomass/dt = loading + photosynthesis - respiration - excretion - mortality - predation - breakage |
