“…Compared with studies worldwide, this working temperature presents similar increases in future scenarios using the RCP 8.5. On the other hand, Saade et al (2021) studied the El Kalb River in a semiarid region. The study indicated that the average annual discharge of El Kalb River shortly (2021-2040) would decrease by around 28%-29% under the three RCP scenarios.…”

This paper provides a technical analysis of a river’s current and future resilience in a watershed with intensive agricultural and fishing activities. The study area was the last section of the Culiacan River corresponding to the river mouth over a lagoon system. Dissolved oxygen modeling was performed using the Streeter-Phelps model to evaluate the river self-depuration capability using Biochemical Oxygen Demand, dissolved oxygen, streamflow, and water temperature data from 2013 to 2020. Fieldwork was carried out to establish the geomorphological characteristics of the river by determining stream velocity, width, and depth and the location of nine sources of pollution on the river. The modeling was performed for three groups of months with different temperatures, identified by hierarchical cluster analysis. Estimates were made for future scenarios, assessing the effect of climate change on the Culiacan River’s self-depuration capability. The results showed that most of the year, the degradation rate of the system results in rapid assimilation of organic matter. However, the modeling indicates that the river would lose its resilience capability under climate change. Thus, it is essential to implement wastewater treatment systems to reduce the environmental impact on the aquatic ecosystem in the river and the lagoon system.

“…Hydrological modeling approaches, particularly the Soil and Water Assessment Tool (SWAT), have been used to tackle these shortcomings and to consider the impact of climate change on water discharge. Some research mentioned the wide application of the SWAT model for assessing the changes in water discharge under climate change conditions on a large watershed scale, such as Saade et al [9], Li and Fang [10], and Ougahi et al [11]. As mentioned in the climate change scenarios, the Ministry of Natural Resources and Environment of Vietnam published and updated these scenarios in the past (2009,2012,2016) and most recently in 2020.…”

Surface water resources have been impacted by climate change. Due to the Coupled Model Intercomparison Project Phase 6 (CMIP6), the Intergovernmental Panel on Climate Change (IPCC) published its sixth assessment report in recent years. Therefore, this study aimed to evaluate the impact of the latest climate change scenarios on surface resources. The Ba River watershed’s streamflow was simulated under current and climate change conditions utilizing Soil and Water Assessment Tool (SWAT) model. Two shared Socio-economic Pathways 1-2.6 and 5-8.5 from ACCESS-CM2, CanESM5, and HadGEM3-GC31-LL General circulation models were used. The simulated annual discharge showed that surface water resources will increase during the 2030s, 2050s, 2080s, and entire periods for all the climate change scenarios in the watershed. Additionally, surface water resource maps of the watershed were created for each period of the climate change scenarios. The results from this study have indicated the effective application of SWAT model in assessing the impact of climate change on water resources.

“…While others used the HMS model, and the results showed high correlation values [9][10][11][12][13]. In other studies, the ARC SWAT program was used to model surface runoff, and they obtained good evaluation coefficients for the results during the verification and testing stages [14,15].…”

This study aims to evaluate the performance of MIKE 11 NAM model for runoff modeling in case of lack of data as a case study on the upper basin of the Orontes River in Syria. In this study, MIKE 11 NAM was relied on as one of the most important hydrological analysis and modeling models. At first, the data used was processed, and the gaps in the time series were filled; then, the data was entered into the model, and the trial-and-error method was used to adopt the model parameters that give the best results. By comparing the results with the measured real values of the flow, it was found that there are large errors and unreliability of the model, which is due to the lack and unreliability of the available data, and this is consistent with the results of other studies conducted in similar cases using the same model. Therefore, this study recommends expanding the possibility of using Mike's model and other models for hydrological analysis and modeling, especially in case of lack of data, because of this great importance in the preparation of hydrological studies, water balance studies, and sustainable development of water resources in the studied area.
