Development of a dynamic water budget model for Abu Dhabi Emirate, UAE

Abstract

In this study, a dynamic water budget model is developed for the Emirate of Abu Dhabi (EAD) in the United Arab Emirates (UAE). The model, called Abu Dhabi Water Budget Model (ADWBM), accounts for a number of drivers such as population growth, economic growth, consumption pattern and climatic factors. Model formulation, calibration, validation as well as simulation results for two future situations are presented in this paper. The two water simulations discuss demand-side options in response to different future water conditions until 2050. The first simulation, namely, baseline (BL) simulation examined water balance in the emirate assuming no change in both water production and consumption. BL simulation results highlight the expected shortages in water resources assuming no modification in the supply side. The second simulation, a more conservative and practical simulation considering water conservation options and sustainable improvements to the supply side was developed to achieve a balanced water budget by reducing the baseline consumption rates. The results show that a significant demand reduction is needed in all demand sectors, reaching 60% in the potable sectors and above 70% in non-potable sectors. Overall, results show that the ADWBM can be used as a numerical tool to produce accurate figures of water supply and demand for the sake of planning and decision making in the water sector of the EAD until 2050.

An Integrated Approach to Water Conservation: Fuzzy Logic Assessment of Water Tariffs in Abu Dhabi Emirate's Residential Sector

“…Data related to the level of each one of these variables in Abu Dhabi households are needed. Although several studies have been done to measure the people's overview of different water-saving policies in Abu Dhabi Emirate (Alhamad, 2018 a), the water usage patterns of Abu Dhabi residents (Yagoub et al, 2019), water demand forecasting (Kizhisseri et al, 2021;Mohamed et al, 2020;Younis, 2016), and the environmental awareness of Abu Dhabi youth (MOEW, 2014), the need for recent robust data was required. Moreover, it is believed that measuring the level of water in uences through their direct indicators gives more reliable and consistent data.…”

Forecasting Future Water Demands for Sustainable Development in Al-Ain City, United Arab Emirates

“…Moreover, various researchers have reported that the per capita water consumption in Abu Dhabi is more than double the global average [28]. Water supply in the UAE is derived from various sources, namely, groundwater, desalinated seawater, treated sewage, and surface runoff from rainfall [29]. These water sources can be classified into two categories, potable and non-potable, depending on the type of demands they are capable of meeting.…”

“…The choice of a forecasting methodology depends, to some extent, on the data that can be obtained through data collection efforts. The forecasting methodologies commonly used include end-use forecasting, econometric forecasting, and time series forecasting [29,[31][32][33][34][35][36][37].…”

Response of two different Phoenix dactylifera cultivars to future climate conditions

“…Similar to other plants date palm is also adversely affected by climate change factors such as elevated levels of CO 2 and UVB radiation. Crop and admirably adapted to the arid and semi-arid environments of the Middle Eastern countries including the United Arab Emirates (UAE) (Kizhisseri et al, 2021). However, variations in rainfall, global warming, gas pollution and decline of water resources are common concerns for date palm production.…”
