About this site
Automating the operation of check-structures in a canal system (irrigation canal, drainage canal, river system) starts with selecting and tuning a suitable control system. This internet site focusses on selecting and tuning water level control systems for canals. In general, choosing the right control system for a canal and tuning the controllers can be difficult and time-consuming: if the control system is tuned too tightly, control becomes unstable; if it is tuned too weakly, the controlled water levels will deviate too much from their target levels.

This site presents a control selection and tuning procedure that is fast and guarantees to find a control system that is reliable, maintains the controlled water levels sufficiently close to target, and is easy to implement in the field! 

This works in two steps:
Step 1: Retrieving the necessary data
These include among others: the definition of your canal system, target water levels, performance criteria, sample time, etc. For a full and detailed list, go to full list of necessary data

Step 2: Solving the control problem
A selection of a control system has to be made and this control system has to be tuned that meets the performance criteria as much as possible, the control system needs to be programmed in a nonlinear hydrodynamic simulation model, the canal response has to be simulated and the results and recommendations on implementation¹ need to be written down in a full report.
