The Impacts of Climate Change on Energy-Water Systems and Economic Analysis

Abstract

In order to develop a valued decision-support system for climate alteration policy and planning, recognizing the regionally-specific features of the climate change, energy-water nexus, and the history of the current and possible future climate, water and energy supply systems is necessary. This paper presents an integrated climate change, water/energy modeling platform which allows tailored climate alteration and water-energy assessments. This modeling platform is established and described in details based on particular regional circumstances. The modeling platform involves linking three different models, including the climate change model from Coupled Model Intercomparison Project Phase 5 under the most severe scenario (Representative Concentration Pathways, Water Evaluation, and Planning system and the Long-range Energy Alternatives Planning system). This is to understand the impacts of climate variability (changes in temperature and precipitation) on water and electricity consumption in Zayandeh Rud River Basin (Central Iran) for the current (1971–2005) and future time period (2006–2040). Climate models have projected that the temperature will increase by 7 °C and precipitation will decrease by 44%, it is also proposed that electricity imports will rise during a severe dry scenario in the basin, while power generation will decrease around 8%.

Climate change simulation and impacts on extreme events of rainfall and storm water in the Zayandeh Rud Catchment

“…In addition, previous studies such as Li N et al 2018 and Javadinejad et al [16] did not analyze the effect of snow melt in storm water simulation under the climate change effects. However, these studies analyze the effect of snow melt in hydrology system of catchment and assess the effect of climate change on snow melt and storm water Javadinejad et al [37] and Javadinejad et al [38] and Javadinejad et al [39] and Javadinejad et al [40] and Dara et al [41].…”

Runoff coefficient estimation for various catchment surfaces

“…Javadinejad et al [29] investigated differences among the engineering explanation for base flow as basic dry weather runoff (which depends on groundwater discharge and system analysis for slow flow) and the scientific explanation for base flow as old flow which is related to tracer analysis.…”

Investigation of water quality in wet and dry seasons under climate change

“…In addition, there is lack of research which used future climate change model to analyze the effect of climate change during wet and dry seasons on water quality [21]. Also, in previous works, such as Javadinejad et al [22][23][24][25][26][27][28] , [29][30][31][32][33][34][35][36][37][38] in China.…”
