Total maximum daily load (TMDL) based sustainable basin growth and management strategy.

This study focused on the development and application of the new approach 'Total Maximum Daily Load (TMDL) based sustainable basin growth and management strategy' to give better insight for the management of surface waters. The establishment of the proposed decision process mainly comprised: beneficial use designations-targets, interrogation of the ambient water quality, selection of variable(s) for TMDL analysis, water quality modeling, basin growth scenarios development and decision on the basin growth plan. The approach was validated through a systematic application study in a field case in Turkey, known as Tahtali Basin. Results revealed that decision process assists policy makers to develop realistic strategies that take into account the basin specific conditions.
