Urban growth contributes to the increase of impervious surfaces, which increases the volumes and peak flows of runoff water as well as the load of pollution discharged into the receiving environment. As impermeable surface cover increases with increasing urbanization, there is a growing need for effective stormwater management that minimizes these adverse effects. It is in this context that this work takes place. The first contribution aims to shed light on the various parameters involved in the calculation of runoff by the nonlinear reservoir model (MRNL) and that of the generalized rational method (MRG) in order to harmonize the results obtained by these two methods. The Green and Ampt model has been introduced into the rational method to simulate the real behavior of permeable surfaces in rainy weather. The results obtained showed the considerable predictive capacity of MRG. The relative errors for the estimation of the maximum runoff rate compared to the measured rate are 7.7% for the MRG and 18.8% for the MRNL. The second contribution of our research is to design an experimental laboratory to analyze the performance of bioretention cells. Different compositions and configurations of bioretention cells have been proposed, in order to analyze their functioning in a versatile way. The infiltration into these cells was simulated using the Green Ampt model developed in the first part of our research. Subsequently, a monitoring approach is suggested in order to monitor and evaluate their performance of these bioretention systems both in terms of reducing the flow rate and volume of runoff and reducing the pollutant load.
