“…The adequate representation of the seasonal progression of the surface temperature has been evidenced in other studies, such as the studies of the Nechako [28] and Soyanggang [59] reservoirs. In the middle zone and near the dam, the surface area presents high values due to low mobility and high retention; this observation was also reported by Azadi et al (2021) [60]. Other studies have shown strong correlations between air temperature and water temperature [36].…”

Water quality impacts on water bodies such as reservoirs are strongly influenced by the hydrodynamics of the system. Although multiple models might be applied, they are limited by the simplification of the variables. In this study, a two-dimensional public domain model, CE-QUAL-W2, was adapted to test whether it would generate an accurate hydrodynamic simulation of the URRÁ Reservoir in Córdoba, Colombia, to understand water quality. The variables to be modeled were temperature and dissolved oxygen due to their importance in ecological terms. Thus, trial and error techniques were used to calibrate and validate the model, varying different parameters such as the wind shelter coefficient (WSC). Although the model accurately predicted the hydrodynamic part by having daily flow information, significant modifications to the eddy diffusivity coefficient were required to simulate acceptable longitudinal currents. This research shows that the CE-QUAL-W2 model fits adequately to tropical lentic systems. However, it is recommended that, for future studies, the modeling be adjusted using hourly data, especially in areas where inflow and boundary conditions are unstable.

“…The global warming contributes the change in surrounding atmosphere by increasing local temperature and variability in rainfall. Globally this situation is expected to affect the hydrological processes [ [ [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] ]]. In recent years, the changing climate effects analysis conducted at different function of water sources worldwide for instance Refs.…”

“…Hence, the availability of the observed data plays a crucial role in the process of choosing appropriate models (Raju & Kumar, 2020). Among the extensive range of hydrological models, scholars emphasize the importance of SWAT (Fan & Shibata, 2015) and IHACRES (Azadi et al, 2021). Within water planning and assessment frameworks, Moghadam et al combined IHACRES with the Groundwater Modeling System (GMS) to model runoff results and predict water levels.…”

This study examines the impact of climate change on the thermal structure, dissolved oxygen (DO), and phosphate (PO4) values of the Karun IV reservoir, Iran. It covers the baseline period (1995-2014) and future projections (2081-2100). Future meteorological variables were derived from the Canadian Earth System Model version 5 (CanESM5) under two emission scenarios downscaled using a machine-learning approach. The continuous daily inflow of the reservoir over an extended period was simulated by employing the IHACRES rainfall-runoff model, in conjunction with the Water Evaluation and Planning system (WEAP) to replicate water level dynamics and outflow. The evaluation of water quality for the years 2019-2020 was conducted utilizing a calibrated CE-QUAL-W2, and any missing data was approximated through empirical relationships. Our findings indicate that the average surface water temperature and the average PO4 concentration, which respectively stands at 22.8 °C and 0.27 mg/L in the baseline scenario, are projected to increase under both SSP1-1.9 (24.4 °C and 0.31 mg/L) and SSP5-8.5 (26 °C and 0.48 mg/L) scenarios. Whereas the average DO concentration of 8.2 mg/L in the baseline scenario is expected to decline in the mentioned scenarios (7.3 and 6.01 mg/L, respectively). The increase in the temperature of the water and the subsequent decline in DO and PO4 levels in deeper waters pose a significant threat to the sustainable growth of aquatic species in the Karun VI reservoir in the future.
