“…To address groundwater sustainability, effective water management is required (Vaux, 2011, Elshall et al, 2020. A nationwide medium resolution (100 m) map of subsidence can help decision-makers develop and implement such effective groundwater policies (Madani, 2014, AghaKouchak et al, 2015, Naderi et al, 2021. A 20-year lifetime of Sentinel-1 will allow a frequent update of nationwide subsidence maps in the future, which can be used to verify whether current water management strategies will have effectively reduced groundwater stress.…”

Abstract. Many areas across Iran are subject to land subsidence, a sign of exceeding stress due to the over-extraction of groundwater during the past decades. This paper uses a huge dataset of Sentinel-1, acquired since 2014 in 66 image frames of 250 × 250 km, to identify and monitor land subsidence across Iran. Using a two-step time series analysis, we first identify subsidence zones at a medium scale of 100 m across the country. For the first time, our results provide a comprehensive nationwide map of subsidence in Iran and recognize its spatial distribution and magnitude. Then, in the second step of analysis, we quantify the deformation time series at the highest possible resolution to study its impact on civil infrastructure. The results spots the hazard posed by land subsidence to different infrastructure. Examples of road and railways affected by land subsidence hazard in Tehran and Mashhad, two of the most populated cities in Iran, are presented in this study.

“…The advantages of system dynamics have enabled scholars to apply it to medical treatments [9,10] , architecture [11] , agriculture [12] , and other fields. It is also used to solve different problems, such as water resources management [13,14] , power resources management [15] , battery solid recovery [16] and energy emissions [17] , population and housing issues [18] , urban development [19] , research on the influencing factors of strategic materials [20] , and research on the influencing factors of transportation [21] . Some scholars have also combined the advantages of system dynamics to solve complex systems with other methods to solve problems.…”

The supply of emergency materials is the fundament of emergency rescues. In view of the demand for emergency materials in major calamities, in this paper, a system dynamics model of emergency materials is constructed from the perspectives of wartime and peacetime. By setting and controlling the relevant parameters and variables, the influence of a variable on the demand and supply of emergency materials and the influence of government strategies on the quantity and provision of emergency material supply are analyzed. We explore the measures that can better ensure the supply to stabilize the social and economic security of the country. The results show that the emergency degree of an event will lead to increases in the amount of government expenditures and in the duration of such expenditures. Meanwhile, the increase in emergency cases will increase the variation range of the supply and demand deviation curve, lengthen the response time to demand, and fasten the growth trend of material supply. The Chinese government adopts comprehensive regulation and control mode, which make the supply and demand reach the equilibrium state more than twice as fast as other control methods. In addition, the promotion of publicity will improve the number of civil materials. A high inflation rate will lead to high imports of government materials, which will consequently affect the supply of emergency materials. The above research findings have important reference significance for the government's emergency materials management.

“…The model is applied to Iran, which is an arid and semi-arid country and is a world power in energy production. Only a handful of comprehensive Nexus-based tools have been developed for application in Iran, and they operate at the river basin scale (see, e.g., Ravar et al 5 ; Bakhshianlamouki et al 22 ) or even smaller scales (see, e.g., Naderi et al 23 ).…”

This study assesses the feedbacks between water, food, and energy nexus at the national level with a dynamic-system model, taking into account the qualitative and quantitative environmental water needs. Surface and groundwater resources are considered jointly in the water resources subsystem of this dynamic system. The developed model considers the effects of reducing the per capita use water and energy on its system’s components. Results indicate that due to feedbacks the changes in per capita uses of water and energy have indirect and direct effects. About 40% of the total water savings achieved by the per capita change policy was related to energy savings, in other words, it is an indirect saving. Implementation of per capita use reductions compensates for 9% of the decline of Iran's groundwater reservoirs (non-renewable resources in the short term) that occur during the five-year study period. The Manageable and Exploitable Renewable Water Stress Index (MRWI) corresponding to water and energy savings equals 214.5%, which is better than its value under the current situation (which is equal to 235.1%).
