Fishing in Goksu Delta |
Background Until the development of artificial irrigation in the Goksu delta on Turkey’s Mediterranean coast, there were only a few lagoons with very salty water which dried out completely in the summer. Since the development of irrigation the return water from the irrigation system has created a series of lagoons which are important for migratory birds and fishing. The overall aim of the project was to assess the long-term viability of the lagoons. |

Scope of work by Water Resource Associates Ltd WRA provided a short term specialist hydrological input. Using data collected by project staff and DSI (the organisation which had developed the irrigation system) a model of the lagoons was developed. The data were sparse, at best monthly (rainfall and evaporation) and in some cases every two months (quality data in the lagoons) for a five year period. There was little information on flow between lagoons so the model was calibrated using data on levels of salinity. |

Results Despite the paucity of the data, and the need to make assumptions about the mixing of sea and irrigation water in the lagoons, the model provided a number of useful conclusions:
