Simple Daily Dynamic Adaptive Operation Rules for WaterResources Optimization

Abstract

In large metropolitan areas of the world the operation andmanagement programs for water supply reservoirs play adominant role in economic, social and cultural growth anddevelopment. An unprecedented population increase inaddition to intensive migration from rural areas add extrapressure on the available limited natural resources suchas land, air and water. Although there are many optimizationtechniques including simple linear or dynamic programming whichmight also include chance constraints, they are rather sophisticated for layman operators who deal with the real timejoint operation of various reservoirs. Furthermore, these operation programs require data on daily basis on hydrologicvariable such as rainfall, runoff, evaporation and others which might not be available in sufficient amounts. It is, therefore, necessary to develop simple, dynamic and adaptiveoperation rules according to the special set up of thereservoirs for each city water resources. This article providesthe fundamentals of Istanbul city water-supply-reservoir operation rules suitable for the combination of already existing Supervised Control And DataAcquisition (SCADA) unit of the city. The operation rules are developed on daily basis under the worstpossible constraints to appear. The suggested model is namedSimple Adaptive Daily Dynamic Program (SADP which runs on the concept of critical duration with unpredictable rainfall-runoff, evaporation and infiltration properties.
