Investigation of natural hazards is crucial for regional water management and disaster preparedness. In this study, trends in annual maximum, minimum and average temperature; annual maximum dry season deficit (DS deficit), dry season duration (DS duration), wet season excess rain (WS excess) and wet season duration (WS duration) were examined. The analyses of extreme events were identified by applying the SPI drought index for multiple-time scales of 1-, 3-, 6-month, for meteorological stations located in the Ceyhan Basin, Turkey. While the homogeneity of the data was analyzed with the Wallis-Moore method, trend analysis was performed with the Mann-Kendall test. In addition, the determination of the change-point year was performed with the Standard Normal Homogeneity Test (SNHT) and Buishand’s Range Test. The findings will be useful to water management decision-makers in the Ceyhan River Basin in assessing the impact of droughts and planning drought mitigation strategies to avoid future drought risks.

A new visible photoactive catalyst (Cu, S/PEG-PVA/TiO2) was synthesized by the sol-gel method. In addition, Cu, S/TiO2 and Bare TiO2 were synthesized to compare their properties and activities. The synthesized catalysts were characterized using XRD, N2 adsorption–desorption measurements, SEM, TEM, EDX, UV-Vis spectroscopy and TGA. The photocatalytic activities of the synthesized photocatalysts were evaluated by measuring the photocatalytic degradation of 4-nitrophenol under visible light irradiation. Then, the impacts of three parameters, (catalyst loading, pH and H2O2 concentration) for optimization and modelization of the 4-nitrophenol photodegradation were studied using the response surface methodology. Optimal conditions obtained from statistical analysis at a catalyst loading of 1 gL−1, pH of 3.98 and H2O2 concentration of 8 mg/L have shown the highest 4-NP percentage degradation of 70.5% in 1 h. The results predicted by the models were found to be in good agreement with those obtained by performing the experiment (R 2 = 0.9443 and Adj-R 2 = 0.9038).

This study examined field validation of discharge measurements with acoustic Doppler current profiler (ADCP) on a remote-controlled boat. Between 2015 and 2020, 112 measurements were assessed at 8 gaging stations in the Paraná River basin, Brazil. SonTek M9 ADCP measurements were compared to rating curves reference discharges. Hypothesis tests were used to verify if mean percentage deviations from the measurements in relation to the reference are equal to zero at a significance level of 0.05. Statistical results indicated that field measurements did not differ from reference values and that percentage deviations are similar to that of previous validation studies. Measurements with ADCP and remote-controlled boat were faster and offered less risk of accidents for hydrometrists than manned boat.

The variability of the estuary location has drawn much attention of the policymakers due to its importance in various environmental issues. This study aims to detect the spatial variation of salts in the water of Shatt Al-Arab River (SAR) in southern Iraq to show the extent of the saltwater penetration into the river during years the 2019-2020. The study used four water sample stations distributed along the southern river part. The study classified the mixing process of the river water into strong and weak stratification as well as partial and moderate stratification. The horizontal distance for the seawater intrusion into the SAR was approximately between 83.7 and 112.4 km. It seems the estuary position moves towards the upstream due to the dominance of seawaters over the river waters in the section. This study is a step towards a better understanding of the salinity issue in the complicated transitional ecosystem.

The availability of a flood hazard map is beneficial during flood risk reduction. However, there is a lack of high-resolution topographic data, which is a map realization obstacle. Therefore, this study aims to construct flood hazard maps based on hazard levels for various flood return periods. The 2D-hydrodynamic from the Hydrologic Engineering Center's River Analysis System (HEC-RAS) and Digital Surface Models (DSM) from Unmanned Aerial Vehicle (UAV) imagery were used for generating inundation maps. The results showed that simulation of return periods for 2 and 10 years illustrated a 37% increase in flood hazard levels. Furthermore, there was an increased danger level for locations that were exposed to flood inundation. This occurred in housing, some roads, and rice fields. Ultimately, this study mitigates flood hazards through the determination of evacuation directions, urban spatial planning, and informed flood mitigation measures.

Finite-length vegetation has been previously studied for its ability to provide resistance against the tsunami by using just the trunk section of the tree stand structures. However, investigating the resilience of the vegetation while taking the crown section into account is yet unknown. Using a limited emergent vegetation model (EVM), this research examined the impact of changing the tree crown heights on the flow structure behavior between the vegetation and its surrounding gap region. Experimental variables included such as tree crown height ( in which is the crown height from the ground surface and is the total tree height), vegetation width to length ratio (W/L), and the initial Froude number condition , which ranged between 0.67 and 0.76. The outcomes demonstrated that, when the vegetation width to length ratio was small, the crown height ratio ( < 0.3) significantly reduced the velocity and fluid force behind the vegetation patch region as compared to no crown (NC) and highest crown height ratio ( > 0.3). On the other hand, the effect of crown cases in the small vegetation patch did not increase the velocity and fluid force in the gap region in comparison with NC. Whereas the increased width of the vegetation patch along with the lower crown height ratio ( < 0.4) further decreased the velocity and fluid force behind the vegetation patch but the increased width of the vegetation patch in combination with the lower crown height ratio increased the velocity and fluid force in the surrounding gap region as compared to its NC case.

When a revetment is selected to protect an eroding coastline, a proper implementation procedure is required to ensure that the revetment is successful. During the last 5 years (2016–2020), Thailand has armored 45.7 km of its shoreline with revetments. Its experience and the lessons learnt from past consecutive revetment implementations have shaped a procedure to integrate engineering, social, and environmental aspects into the whole process. The nine stages involved in Thailand’s revetment implementation are elaborated by using the Laem Ngoo beach revetment as an example. Although Thailand’s 2021 revetment implementation procedure may not be the best approach in different physical and social environment, it may be useful for coastal practitioners to learn from and follow if they find such an approach to be sustainable.

Presented here are considerations for designing a hydraulic model involving a broad reach of braided, sand-bed channel used to aid the design of a grade-building structure (GBS) for retaining bed sediment upstream of a sediment-deposition plain formed by a sediment-retention dam. The results focus on the similitude and calibration considerations needed to simulate bed-sediment transport along a large braided channel. Key variables in this regard were flow discharge, channel slope and sediment-transport rate. Additionally, the results describe how the GBS evolved in design from initially comprising four walls that lengthened flow path (thereby causing sediment deposition) to being four walls with openings that dispersed flow and consequently spread sediment deposition across the reach. The addition of rock aprons and wall bunds (curved, wall ends), enhanced sediment retention, reduced scour, and mitigated an under-wall seepage concern. In final design, the GBS retained approximately 83% of the bed sediment entering the reach over the test duration.

A numerical model was used to analyze the effect of sediment transport and flow depth on soil moisture profiles from a simulation of the hypothetical irrigation furrows. The Saint Venant and sediment continuity equations were solved by using MacCormack scheme based on finite difference method to analyze the overland flow and sediment transport, and Richards equation was used to analyze the subsurface flow, which was solved by using a mass conservative fully implicit finite difference method. Flow depth significantly affected the moisture profiles in irrigation channels while the effect of sediment-laden water on the moisture profiles was observed insignificant. The model was used to study the effect of infiltration on moisture profiles and soil water retention curve (SWRCs) in irrigation furrows. It was observed that infiltration significantly affected and altered the moisture profiles and soil water retention curve (SWRC). Among the different soil parameters (av and nv ) and saturated hydraulic conductivity ( ) significantly affected the moisture profiles, while and influenced the soil water retention curve (SWRC) as compared to other retention parameters.

This article describes the evaluation performance of two constraint processing treatments (TCPT) techniques: the advantages of feasible (SF) and adaptive penalty (SP) solutions in combination with differential evolution (DE). Our approach is tested on Dez reservoir data related to water supply and hydropower operation to evaluate the accuracy of our approach. The results of the simulations on water supply and hydroelectric exploitation with spillway parameters forecast better prospects for the water resources of Ntem water flow. Indeed, to demonstrate the robustness of our approach, we did a simulation of the test functions to assess their potential. Then, we did a comparative analysis of our approach with other algorithms combined with the constraint treatment method. The quality of the results obtained by TCPTDE is much better in determining optimal solutions than the genetic algorithms, the swarm of particles, the colony of bees and the Drone Squadron Optimization (DSO) hybridized with TCPT.
