2. Multi-module smart drainage management approach

Our proposed simple smart drainage management approach to reuse drainage water for fertigation through improved drainage control for overcoming summer drought consists of three modules (Figure 1): (i) meteorological forecasting, (ii) hydrological simulation, and (iii) the practical implementation of irrigation and drainage control using novel ICT-based sensor network solutions. The implementation module has two parts: an automatic drainage control regulating the amount of agricultural field water and the reuse of drainage water for fertigation feeding back in an automatically controlled manner into the drainage system.
