水的有效利用应涉及平衡绿色水（GW）和蓝色水（BW）的可持续发展的决策。更具体地说，灌溉水管理的重点应该从水重角度转向考虑包括GW流量在内的全部水平衡。本研究提出了一种系统动态平台的建模方法，以最小化流域内的生物重量与生物总重量之比，同时最大化农业总利润。本文考虑了任何GW / BW比值的降低与通过改变土地利用和种植模式可能产生的区域经济成就变化之间的折衷。本文探讨并提出了利用水足迹概念降低Zarrinehrud河流域中、干、湿年BW / GW比值的可能性。结果表明：在水足迹措施所解决的经济目标和水重/水重比的所有组合下，流域的水经济绩效都比目前的实践有了很大的提高。如果需要在目标之间进行更精确的权衡，则可以系统地改变权重或采用多目标优化算法。
The efficient use of water should involve decisions for balancing green water (GW) and blue water (BW) use for sustainable development. More specifically, the focus of irrigation water management should be redirected from a BW perspective toward considering the full water balance, including GW flow. This study presents a modelling approach in a system dynamic platform for minimizing the BW to GW ratio in a water basin while maximizing total agricultural profit. The paper considers the compromise between any reduction in the GW to BW ratio and the possible changes in the economic achievement of the region through varying land use and cropping patterns. This paper explores and presents the possibilities of reducing the BW to GW ratio in the Zarrinehrud River-basin for moderate, dry, and wet years using the water footprint concept. Results show that under all combinations of economic objective and BW to GW ratio addressed by water footprint measures, the hydro-economic performance of the river basin may substantially be improved as compared with the current practice. Either weights may systematically be changed or multiple objective optimization algorithms may be employed if a more precise tradeoff between the objectives is needed.
