A proposal for coding of islands is given in Appendix xx. The islands can be identified by the code of the sea they lie within, followed by a sequence number according to the distance from the mainland. In the island coding only islands with surface flow (around 2500 objects) are included. The coding is in hexadecimal digits (00-FF) thus allowing 255 islands to be identified within a Sea. The code 00 is reserved for surface waters on mainland. Will be any other appendices? Q: Will be any other appendices? We suggest to add more details in app.7

Conditional Lake Identification (LL) It is proposed to reserve a maximum of two characters for this code segment. The code could consist of numbers and characters. Feature Identification (LL) linked to EE 1) Not just lake, but also other hydrological special phenomena (feature) are identified by sequential enumeration. It starts at river outflow. 2) We propose character value type if there is no additional feature, the segment number is 00 3) Explanatory figures and text should be added such is Canalized rivers are coded as part of a river system. Artificial canals belong to specific entity type canal and are coded with an identifier. Identifier is needed if more than one canal are recognized. An additional foreign key establishes the relation between the canal and the water basin.
