“…For this simulation, the total Saudi Arabia's water demand for 2025 is divided by into the three main sectors-agriculture, industries, and households, given that agriculture accounts for 88% water use in Saudi Arabia with 3% usage by industries and 9% usage by households (Abderrahman, 2006). Thus, there are three nodes representing agriculture, industry, and household with consumption c j of 876.41 , respectively.…”

The objective of this paper is to introduce models to determine an effective, feasible, and cost-efficient strategy for Saudi Arabia's water supply system to meet its projected demand in 2025. This paper uses cost minimizing and production maximizing approaches to build the models. The water management system is divided into three processes-desalination, distribution, and wastewater treatment. For desalination and wastewater treatment aspects of the water supply, we use a Cobb-Douglas production maximization model. The model determines the optimal levels of different inputs that maximize the production of usable water, given the Saudi Arabia government's budget constraints. For the water distribution model, a cost function is minimized with the 2025 water demand constraint and is used to determine the optimal diameter of the pipes and hydraulic head. Using the desalination process model, the paper found that the optimal level of input of electricity is 4.9 billion kW h and the maximized water output is estimated at 3.3 billion m 3 . In addition, using the wastewater treatment model, the paper found that the optimal level of electricity input is 26.5 billion kW h annually and the maximized level of water production is 7.7 billion m 3 . The water distribution model estimates that, given the 2025 water demand in Saudi Arabia, the set-up and operating cost of the water distribution grid is approximately $68.88 million. The model also estimates that a minimum pipe diameter of 5.37 m and hydraulic head of 1186.14 m is required to meet the demand of three sectors-agriculture, industry, and domestic.

“…Increasing costs to producers, however, would place further strain on the finances of water utilities. Under the current cost structure, total annual revenues do not exceed 2.5% of annual expenditure (Abderrahman, 2007), with most revenues coming from the industrial sector, as residents pay less than USD 0.05/m 3 (Zetland, 2014). For this reason, any shift to more expensive solar desalination technologies is likely to be politically sensitive.…”

“…Besides the barrier effect induced by the occurrence of underground structures across groundwater flow, some modification of the water budget may be caused by the interaction between groundwater and these underground structures (Morris et al, 2003;Attard et al, 2016). For instance, leaky sewer and water supply plumbing networks may act as recharge (Abderrahman, 2006) or drain (in the case of sewers), limiting the water table rising above the structure (Dassargues, 1997). Generally speaking, human settlement nearby fluvial environments results in significant SW and GW decline due to pumping wells for domestic and industrial usages, as well as for underground structure protection and the construction of un-derground infrastructures (Machiwal et al, 2018;Schirmer et al, 2013).…”

“…The main linear estimators are inverse distance weighting (Gambolati and Volpi, 1979;Philip and Watson, 1986;Rouhani, 1986;Buchanan and Triantafilis, 2009;Sun et al, 2009) and influence polygon or moving average (Vicente-Serrano et al, 2003). These different methodologies were compared in several studies and kriging was found to be a better estimator in terms of cross-validation and performance than the other linear interpolators (Varouchakis and Hristopulos, 2013;Emadi and Baghernejad, 2014;Adhikary and Dash, 2017;Ohmer et al, 2017) . Although the linear estimation methods provide unbiased results, they do not account for the spatial heterogeneity of the sample distribution.…”

Abstract. A water table mapping method that accounts for surface-water–groundwater (SW-GW) connectivity and human pressure, such as pumping and underground structures occurrence, has been elaborated and tested in the heavily urbanized Parisian area. The method developed here consists of two steps. First, hard data (hydraulic head) and soft data (dry wells) are used as conditioning points for the estimation of the SW-GW connection status. A disconnection criteria of 0.75 m is adjusted on observed unsaturated zone depth (UZD). It is a default value in areas where such data are missing. The second step consists of the final mapping of the water table. Given the knowledge of the disconnection criteria, the final map is achieved with an ordinary kriging of the UZD that integrates the surface water elevation without unsaturated zone where it is relevant. The methodology is demonstrated on two datasets of UZD observations that were collected under low- and high-flow conditions.
