“…The examination of the asset accounts obtained from this study shows that the volume of water output from the last station, total evaporation and transpiration and precipitation are 17.3, 4755 and 5888 MCM, respectively; these values in the reports provided by IRWA are respectively, 18, 4498 and 5983 MCM and are reported to be in relatively good agreement. Also, the amount of blue water and green water obtained in the research is close to the results of Basaltpour et al (Besalatpour et al, 2020).…”

Historically, there has been a dispute over water allocation between users and policymakers in Iran's Zayandeh‐Roud Basin (ZRB). In this study, we used the “System of Environmental‐Economic Accounting for Water” (SEEAW) framework in combination with the hydrologic model “Soil and Water Assessment Tool” (SWAT) to achieve the water balance in ZRB. We used SEEAW to combine a wide range of water‐related statistics across stakeholders and SWAT to evaluate the unknown agricultural water use. The SWAT model is calibrated based on the stream flows and crop yields in the basin. The model assess the renewable water of the basin into two components, about 363 and 70 mm as green and blue water, respectively. Also results from the physical water supply and water use tables demonstrates that the agricultural sector uses 78% of the total renewable freshwater, followed by the residential, 16%, and the industrial sector, 6%. The flows of water from source to services in ZRB are traced based on the water supply and water use tables. The flow diagram shows that 8 MCM of industrial reused water was transferred to the agricultural sector, and 137 MCM and 18 MCM of water from the wastewater treatment plants to the agricultural and industrial sectors, respectively. Furthermore, the results show that the index of the basin dependence on groundwater resources is high (61%), the value of water stress is high (0.88) and the dependence of the basin on transboundary water resources is 30%. Therefore, this method is highly beneficial for achieving a conceptual water balance in disputed basins without enough agricultural water uses data.

“…The Zayande-Rud dam controls spring flooding and regulates water due to high downstream demand during summer. This kind of operation policy develops summer cultivations, produces 55.2 MW of electricity, and allocates water to downstream water users (Besalatpour et al 2020). Recently, due to the high amount of water demand, reduction in rainfall amounts, and recent droughts, it has become vital to consider and study the impact of different human interventions on the hydrological behaviour of the basin.…”

“…As different calibration procedures produce different parameter sets, we used two different approaches here for a comparison of observed and simulated discharge data to provide more confidence in the results. These include (i) the 'global approach', where all discharge gauges from all river basins were calibrated within a single calibration framework and (ii) the 'regional approach' (Besalatpour et al 2020), where discharge gauges were separately calibrated for different water regions. Based on hydro-climatologically different conditions in upstream and downstream Zayandeh-Rud dam, and tributary rivers which are ungauged but highly managed for different purposes, we considered seven major water regions for the regional calibration.…”

In a human-dominated world, access to sustainable water resources has led to complex management policies that affect hydrological droughts. Applying the best approach to assess the contribution of these human-made changes to hydrological droughts is still underexplored. In this study, the individual and joint impacts of dam and inter-basin water transfer projects are quantified for the characteristic changes of hydrological drought using a developed data-based framework and were tested in a semi-arid, data-scarce basin in central Iran. The proposed data-based framework combines the upstream–downstream comparison method and the individual–station–drought analysis. This framework could properly assess the individual and joint contributions of dam and water transfer projections to making aggravations or alleviations in hydrological drought. It identified the dam and joint impacts of the dam with water transfer by 66 and 55%, respectively, as the most effective human intervention to alleviate the duration of hydrological drought. The proposed framework gives the flexibility to form different comparative analyses by using different types of flow data to assess the impacts of human interventions. This framework is also applicable in other regions to quantify the contributions of point-based human interventions to hydrological droughts. The comprehensive knowledge of solutions to alleviate the adverse impacts of droughts can reduce the damage in water-stressed regions.
