 this folder contains information on alle optimizations of RTC which were conducted in MIKE+ via Mike+py
 
+The Optimizastion_control_rules.ipynb is used to optimise the input parameters of the control elements of a drainage system using a MIKE+ model. 
+The aim is to minimise the runoff from the system into the receiving watercourse without causing flooding on the roads.
+
+The script receives the MIKE+ model, a list of all precipitation events (config_event.xlsx), 
+a list of the parameters to be optimised (config_parameters.xlsx) 
+and a list of the structures (structures.xlsx) for which overflows are to be minimised. 
+The files should be saved in the same folder as this script, as relative paths are used.

 # equal-filling-degree (EQF)
 
 no optimization was used for the implemented EQF model but a script was used to get the storage curves.
