Performance of a RBSN under the RCP Scenarios: A Case Study in South Korea

Abstract

According to the Intergovernmental Panel on Climate Change's (IPCC) Fifth Assessment Report, the amount of precipitation in South Korea would increase regardless of the reduction of Greenhouse Gas (GHG) emissions. However, at the same time, it is expected that the temporal and spatial rainfall variation would also increase. Due to the impact from typhoons, 90% of the annual precipitation in Korea occurs in July, August, and September. Moreover, the Representative Concentration Pathways (RCP) scenario projected that the average precipitation in this period is expected to increase markedly, especially over the next 100 years. These predictions imply an increased variability of available water resources. In this study, we assessed a RBSN (rain barrel sharing network) as an efficient way to respond to the future climate change projections under the RCP scenarios when compared to the historical data. We proposed an evaluation procedure for the reliability, resilience, and vulnerability of RBSN based on a storage-reliability-yield (SRY) relationship. The result shows that the reliability and resiliency of a RBSN will improve but be more vulnerable compared to the results from the historical rainfall data. However, even in the climate change condition, the results showed that a RBSN still contributes to reduce vulnerability. The results of this study imply that a RBSN is an effective and alternative measure that can deal with the impacts of climate change in the future.

Stormwater Harvesting from Roof Catchments: A Review of Design, Efficiency, and Sustainability

“…Water end-uses, total water consumption, and catchment area were among the found building attributes [67,68]. The study of Kwon et al (2018) also implied that collecting rainwater on a neighborhood scale rather than per individual building can be more economically viable [69]. Table 3 compares RWH approaches regarding occupancy category, catchment area, daily consumption, payback period, and Internal Rate of Return (IRR) corresponding to the number of years.…”

Rainwater Harvesting System Analysis for Semi-Arid Climate: A Daily Linear Programming Model

“…Tank size is one of the main concerns in designing RWHSs since it directly affects the financial feasibility of the system and performance indicators such as reliability, resilience, and vulnerability [11][12][13][14][15]. Generally, approaches based on a water balance model are used to identify the best tank size.…”

Spatiotemporal Change in Groundwater Sustainability of Bangladesh for the Period 1995-2019

“…In recent years, the Resiliency-Reliability-Vulnerability (RRV) (Hashimoto et al, 1982) concept has been used to evaluate sustainability in resources against hazard risk (Hazbavi et al, 2019;Maity et al, 2013;Sung et al, 2018). In hydrology, it has been used to assess sustainability in the integrated ground and surface water irrigation (Onta et al, 1991), reservoir operation (Kwon et al, 2018), water resources management (Ashofteh et al, 2017;Sarzaeim et al, 2017), water supply system (Karamouz et al, 2017), water distribution system (Aydin et al, 2015), and flood protection systems (Simonovic and Li, 2004). Besides, it has been used for assessing urban flood risk (Ahmad and Simonovic, 2013) and future water deficit (Mondal et al, 2010).…”
