“…Groundwater volume balance is described in Equations (1) to (7). For the hydrologic system to be in balance, water inflows to aquifer must equal the water outflows [5]. (10) where: parameters γ is net portion of agriculture irrigation water inflows to groundwater balance zone; λ, net portion of precipitation inflows to groundwater balance zone; α, net fraction of surface water inflows to groundwater balance zone; β, net portion of municipal sewage water inflows to groundwater balance zone; and μ is net portion of artificial recharge water inflows to groundwater balance zone.…”

“…Dependence upon groundwater is specially important in areas such as Northern China, Eastern Europe, Northern India, the US Great Plains and the largest parts of the middle east countries [4]. In the recent decades, due to many different factors, including climate change effects towards be warming and lower precipitation, as well as some structural policies such as more intensive harvesting of groundwater for agriculture development, low price of irrigation water, inefficient water use, the level of groundwater has decreased in most areas of Iran [5]. Recent forecasts suggest that the combined effects of population growth, global warming and land use change will, in the near future, lead to even greater reliance on groundwater for public water supply [6,7].…”

“…Groundwater resources, which represent about one quarter of freshwater on earth [13], are the only main source of irrigation and drinking water in somearid and semi-arid regions such as the Hamedan-Bahar Plain, situated in the western Iran [5]. The aim of this study is to analyse and forecast the vulnerability of groundwater level and agriculture sector water consumption in Hamedan-Bahar plain, under different climate change and agricultural economic policies using the system dynamics (SD) approach.…”

Abstract:In the recent decades, due to many different factors, including climate change effects towards be warming and lower precipitation, as well as some structural policies such as more intensive harvesting of groundwater and low price of irrigation water, the level of groundwater has decreased in most plains of Iran. The objective of this study is to model groundwater dynamics to depletion under different economic policies and climate change by using a system dynamics approach. For this purpose a dynamic hydro-economic model which simultaneously simulates the farmer's economic behavior, groundwater aquifer dynamics, studied area climatology factors and government economical policies related to groundwater, is developed using STELLA 10.0.6. The vulnerability of groundwater balance is forecasted under three scenarios of climate including the Dry, Nor and Wet and also, different scenarios of irrigation water and energy pricing policies. Results show that implementation of some economic policies on irrigation water and energy pricing can significantly affect on groundwater exploitation and its volume balance. By increasing of irrigation water price along with energy price, exploitation of groundwater will improve, in so far as in scenarios S15 and S16, studied area's aquifer groundwater balance is positive at the end of planning horizon, even in Dry condition of precipitation. Also, results indicate that climate change can affect groundwater recharge. It can generally be expected that increases in precipitation would produce greater aquifer recharge rates.

“…At present and in the future, the basic goal of the reform of water price in China is to establish the water price mechanism, which can reflect the shortage of water resources, improve water efficiency, promote sustainable utilization of water resources [2]- [4]. Besides the water price shall gradually reflect total cost of water, promote the water company achieve real business operation, and promote the whole society to save water, use water efficiently [5].…”

With the development and reform of water price policy, the most common view is that the total cost of water price can reflect the tradable traits of water resources, which can enhance the water use efficiency and achieve water resources sustainable utilization. Besides in actual pricing operation, from the angle of protection cost, water price characterizes the cost of controlling pollution and protecting water environment. Based on the two factors of water environment capacity and ecological water consumption embodied by the environment water price, this paper puts forward an effective environmental water price calculation model based on three elements of sewage treatment fee, ecological water price and water quality maintenance fee. And this paper takes the data of Hefei as an example, calculates reasonable environmental price, comparing which with the existing price, and finds the main existing problem which needs to be solved urgently in management.

Poor performance of irrigation networks necessitates their improvement. One of the measures for performance improvement is application of automatic systems such as hydro‐mechanical gates. The decision‐making process for application of automatic systems is a complicated task. Reasons for this complexity are the wide range of existing technologies to be selected from, interactions between components and economic and social short‐ and long‐term impacts. Development of a suitable model which addresses all aspects of automation is needed. One suitable technique for coping with this is a system dynamic approach. In this research, the dynamic behaviour of irrigation networks using automated control systems is investigated and its conceptual model is developed as a first step of a system dynamic model. A questionnaire based on system dynamic archetypes was designed and completed by irrigation experts from six irrigation networks in Iran. In addition, interview techniques were used to collect data. The conceptual model was developed by a system dynamic approach. The conceptual model includes fixes that fail, limits to growth, eroding goals, success to the successful, and shifting the burden archetypes. The interactions between social, managerial, economic, technical and water resources in the long term, which play a significant role, are well elaborated in the developed conceptual model.
