Algual detachment in response to flushing with reference shear stress equal to the first time step
21 juin 2012, par Louis Poirel

Definition
The rate of accidental detachment of fix algae $ b_i $ towards drift algae $ a_i $ is calculated in each section as follows :
$$ \frac\partial B_i\partial t(x,t) = -S\frac\partial A_i\partial t(x,t) = -\frac1\delta\left ( \frac\tau_0(x,t) - \tau_0(x,0)\tau_0(x,0) - s_B \right (...)
Algal growth (PhD Thesis, O. Fovet, 2010, p.101)
21 juin 2012, par Louis Poirel

Definition
The biomass growth is calculated at time t, in each section x as follows :
$\frac\partial B\partial t(x,t) = \mu(x,t) B(x,t) F_lim(B’(x,t))$
where :
$F_lim(B’(x,t)) = \left ( 1 - \fracB’(x,t)B_Max \right )$
$ \mu(x,t) = \mu_0 \theta^T(t)-T_0 \fracI(x,t)I_opt e^1- (...)
Exponential growth with fixed coefficient
21 juin 2012, par Louis Poirel

Definition
This law changes the concentration of a class depending on an other class concentration (or eventually itself), and two fix coefficients $ k $ and $\alpha_k$ as shown here :
$ \fracdC_idt=k C_j^\alpha_k $
Classic use
Numerous solutes have a first-order kinetics with an equation (...)

Transport and exchange equation
Water temperature in the network is a fonction of upstream temperature and thermal exchange with atmosphere and substratum.
The general equation is :
$\frac\partial ST\partial t+ \frac\partial QT\partial x= \frac\partial\partial x\left(DS\frac\partial (...)
