An Integrated Model for Simulating and Evaluating Water Resources Sustainability at Laoshan Region

An integrated model was developed for evaluating water resources sustainability. In the model, a new index was developed based on nineteen indicators related socio-economic, eco-environment and water resources. The interrelationships between indicators were quantified based on mathematical models. The integrated model was applied to simulate the water resources sustainability in Laoshan Region successfully from 2010 to 2030 after validation and calibration using historical data which has low relative errors and relative standard deviation (< 10%). The results indicate that the sustainable solution to water resources utilization in Laoshan Region is to supply different types of water resources to different water resources demand sectors based on requirements on water quality and quantity. The integrated model developed in this study is useful for decision-makers to simulate and evaluate the water resources sustainability.
