“…The RIBASIM 7.01.24 program is one of the water allocation models that can be used at the planning stage of water resources development [16], as well as operationally to assist tactical decision making (eg as a means of negotiating reservoir operations or granting industrial water extraction permits). In this research, RIBASIM 7.01.24 program is used to analyze the water balance in a basin or river that will be simulated [17].…”

The Saba watershed is the main water source for irrigation areas downstream of the Saba river. The Titab Reservoir was built to be able to meet the continuity of irrigation water supply, especially during the dry season. This study aims to analyze the fulfillment of irrigation water requirements provided by the Titab reservoir. The study began by collecting data first, in the form of primary and secondary data. Primary data is used to see the existing conditions. Secondary data is used for irrigation requirements analysis and simulation. The secondary data used for manual calculations are 15 daily rainfall data, 15 daily measured discharge, and climate data for 10 years from 2006-2016. The output of these data is the need for irrigation water, the potential evaporation, and the discharge reliability used for the simulation. The simulation was carried out using the RIBASIM 7.01.24 program by entering the calculated data and the existing reservoir data. The simulation results show that the irrigation water needs supplied in each irrigation area are not sufficient according to the plan and the reservoir reliability value is low, namely 57.35%.

“…(2012), and Ouria and Sevinc (2016) concluded that the construction of the dams should be blamed for these changes. There also exist studies which addressed issues such as the development of farmlands (e.g., Alizade Govarchin Ghale et al., 2017, 2019; Hesami & Amini, 2016; Schulz et al., 2020), the effect of dust on the climate of the region (e.g., Alizade Govarchin Ghale et al., 2021; Parsinejad et al., 2022), depletion of the groundwater (e.g., Amirataee & Zeinalzadeh, 2016; Ashraf et al., 2017; Javadzadeh et al., 2020; Sheibani et al., 2020; Vaheddoost & Aksoy, 2018; Wurtsbaugh et al., 2017), or the mismanagement of the water resources mostly by the decision‐makers (e.g., Ahmadzadeh et al., 2022; Alizadeh‐Choobari et al., 2016; Alizade Govarchin Ghale et al., 2018, 2019; Khazaei et al., 2019; Khatibi et al., 2020) as the main reasons for this drastic decline.…”

Lake Urmia's water level decline and its socio-environmental drawbacks were continuously addressed by many researchers over the last two decades. In the mid-2000s, major changes associated with the lake water level were determined with a jump, initiated in 1993 and a subsequent decline in 1998 (Fathian & Vaheddoost, 2021a, 2021b. Since then, the lake's surface area was continuously degraded that urged decision-makers to take immediate actions. To this end, many studies have been conducted to realize, simulate, and describe the causes and aftermath of the phenomenon. Although no general conclusions are made, several issues are addressed for this drastic decline. The effect of climate change on the Lake Urmia basin was addressed by Abbasian et al. ( 2020),

“…The applications of coupled simulation-allocation models in water resources are abundant, for instance, the evaluation of the reliability between water supply and demand in climate change scenarios using coupled SWAT-RIBASIM [26]. Within the study, the SWAT model was utilized to simulate the basin hydrology for the baseline and future climate periods, while the RIBASIM model was used for water allocation based on the current supply-demand chain and predefined governmental water allocation rules for different water uses.…”

Assessing Climate Change Impact on Water Resources in Water Demand Scenarios Using SWAT-MODFLOW-WEAP

In this article, we present the use of the coupled land surface model and groundwater flow model SWAT-MODFLOW with the decision support tool WEAP (Water Evaluation and Planning software) to predict future surface-water abstraction scenarios in a complex river basin under conditions of climate change. The modelling framework is applied to the Dee River catchment in Wales, United Kingdom. Regarding hydrology, the coupled model improves overall water balance and low-streamflow conditions compared with a stand-alone SWAT model. The calibrated SWAT-MODFLOW is employed with high-resolution climate model data from the UKCP18 project with the future scenario of RCP85 from 2020 to 2040. Then, water supply results from SWAT-MODFLOW are fed into WEAP as input for the river reach in the downstream region of the river basin. This system is utilized to create various future scenarios of the surface-water abstraction of public water supply in the downstream region—maximum licensed withdraw, 50% authorized abstractions, monthly time series with 1% increases in water use, and maximum water withdraw per year based on historical records repeated every year with 1% increases in water use—to estimate the unmet demands and streamflow requirement. This modelling approach can be used in other river basins to manage scenarios of supply and demand.
