“…where Rel i , Res i , Vul i and Max.De f i are reliability, resiliency, vulnerability, and maximum deficit, respectively. These four performance criteria have also been used in previous studies of this kind [16,17]. Reliability, Rel i , is the probability (percentage of time) that the water demand is fully supplied, specifically, the ratio of the number of times De f i t = 0 to the total number of time intervals, N:…”

The present study aimed to quantify the future sustainability of a water supply system using dynamically-downscaled regional climate models (RCMs), produced in the South Asia Coordinated Regional Downscaling Experiment (CORDEX) framework. The case study is the Boukan dam, located on the Zarrine River (ZR) of Urmia’s drying lake basin, Iran. Different CORDEX- models were evaluated for model performance in predicting the temperatures and precipitation in the ZR basin (ZRB). The climate output of the most suitable climate model under the RCP45 and RCP85 scenarios was then bias-corrected for three 19-year-long future periods (2030, 2050, and 2080), and employed as input to the Soil and Water Assessment Tool (SWAT) river basin hydrologic model to simulate future Boukan reservoir inflows. Subsequently, the reservoir operation/water demands in the ZRB were modeled using the MODSIM water management tool for two water demand scenarios, i.e., WDcurrent and WDrecom, which represent the current and the more sustainable water demand scenarios, respectively. The reliability of the dam’s water supply for different water uses in the study area was then investigated by computing the supply/demand ratio (SDR). The results showed that, although the SDRs for the WDrecom were generally higher than that of the WDcurrent, the SDRs were all <1, i.e., future water deficits still prevailed. Finally, the performance of the water supply system was evaluated by means of risk, reliability, resiliency, vulnerability, and maximum deficit indices, and the combination of the indices to estimate the Sustainability Group Index (SGI). The findings indicated that, compared to the historical period for both the water demand scenarios, WDcurrent and WDrecom, the average SGI of each RCP would be decreased significantly, particularly, for the more extreme RCP85 scenario. However, as expected, the SGI decrease for the WDrecom was less than that of the WDcurrent, indicating the advantage of implementing this more sustainable water demand scenario.

“…Socio-economic developments increase the basic demand for water and generate new habits and patterns for the consumption of fresh water (Bouayoune et al 2017). Today, people need fresh water for a variety of activities, from eating and drinking to bathing, washing, toilets, and tertiary needs such aesthetic and recreational purposes (Karamouz et al 2017;Lisiak et al 2017). This is known as fresh water use for domestic needs.…”

“…To identify the problems and challenges in urban water supply, water resources planning programmes are aimed at improving the coverage and capacity of services needed to meet urban demands and to supply the raw materials required for the provision of urban water (Karamouz et al 2017). Efforts are made to prioritise rehabilitation activities and the operation and maintenance of natural water infrastructure, in order to restore and optimise the function of raw water infrastructure.…”

Population growth over recent years in Depok has increased demand for fresh water for daily necessities. These necessities include the fresh water required by both settlements and commercial operations. The purpose of this study is to analyse the demand for fresh water created by the population growth of Depok in realising its development as a sustainable city. This study uses a quantitative approach presented through narrative analysis. In 2016, the average water requirement of Depok's population of 2,180,000 people was 3,070 litres/second in the dry season and 5,983 litres/second in the rainy season. Population projections for 2030 suggest that the population of Depok will have increased to 3,543,101 people, and that the average water requirement will then be 4,990 litres/second in the dry season and 9,724 litres/second in the rainy season. Planning alternatives proposed to meet these needs include improving the evaluation of freshwater production capacity and developing freshwater supply systems. Thus, it expected that the projected freshwater needs of Depok in 2030 can be fulfilled. This expectation can be managed and achieved through participation by society and government. However, obstacles are still faced, mainly due to more recent cultural attitudes towards using water.

“…For the Tuwei River, through the analysis of multiple feedback and non-linear interactions between the various elements of the system, a complex SD model was established [ 18 ]. The third is to use the relationship between supply and demand to study ecological carrying capacity of water, based on the combination model or SWAT model to evaluate the water resources supply and demand [ 19 , 20 ]. From above analysis we found that most of the water situation analysis is from water flows angle.…”

Climate change, population growth, the development of industrialization and urbanization are increasing the demand for water resources, but the water pollution is reducing the limited water supply. In recent years, the gap between water supply and demand which shows water scarcity situation is becoming more serious. Clear knowing this gap and its main driving factors could help us to put forward water protection measures correctly. We take the data of Huaihe River Basin from 2001 to 2016 as an example and use ecological water footprint to describe the demand, with the water carrying capacity representing the supply. We analyze the water supply-demand situation of Huaihe River Basin and its five provinces from footprint view in time and space. Then we apply the Logarithmic Mean Divisia Index model to analyze the driving factors of the ecological water footprint. The results show that: (1) the supply and demand balance of Huaihe River Basin was only achieved in year 2003 and 2005. There is also a large difference between Jiangsu province and other provinces in Huaihe River basin, most years in Jiangsu province per capital ecological footprint of water is more than 1 hm2/person except the years of 2003, 2015, and 2016. But other provinces are all less than 1 hm2/person. (2) Through the decomposition of water demand drivers, we concluded that economic development is the most important factor, with an annual contribution of more than 60%. Our study provides countermeasures and suggestions for the management and optimal allocation of water resources in Huaihe River Basin, and also provides reference for the formulation of water-saving policies in the world.
