Supermodel As a Proposed Necessity for Integrative Casual Chain Models in Water Resources

Nowadays, models as the most important analytical tools, severely have entangled water resources management in rigid structures; like, it is hard to solve a water resources problem as a separate part of using models. This study efforts to determine the way of scientific studies of water resources modeling and investigate the master view of each models using qualitative content analysis method. Content analysis of published papers in journal of Iran- Water Resources Research during 2005- 2017 years demonstrate that more concentrate of surface water modeling was on model assessment in order to allocate, manage and planning, while of the groundwater, the challenge was on achieve optimal model to more exploitation of resourse water. Investigation aim of modeling show a discordance in choose of optimal model that can it's know deu to natural of model and phenomenon examined. Hence, it could be suggested that providing a supermodel may integrate and progress the outputs of water resources models. The necessities of the supermodel included (a) integrated view to water resources models, (b) complicated situations of climate and nature of Iran, (c) pluralistic origins and usages and (d) institutional complication and numerousness; that tried to change the route from “estimate to allocate” to “aim to estimate” in water resources research.
