Summary: This study investigates rainfall and drought characteristics in southeastern Australia using data from 45 rainfall stations. The results show an increasing trend in annual total rainfall, but a significant negative trend in the medium term. Winter is dominated by a negative trend, while summer and spring seasons show a positive trend. April is the driest month. Positive trends on droughts are observed in the inner parts of the study area, while a negative trend is detected in the south, southeast, and northeast.

Summary: This study investigates variations in streamflow at 20 stations in the upper Indus river basin using different methods, finding that extremely low flows are increasing more significantly than extremely high flows. This may lead to constant pressure on water resources availability in the lower Indus plains where agricultural activities are dependent.

Summary: This study analyzed the recent effects of climate change in the upper Geum River basin in South Korea by examining 17 extreme climate indices based on 33 years of daily precipitation and temperature data. The results indicate an overall increase in temperature intensity, decreased cold duration, increased heat duration, intensified precipitation, prolonged summer season, and shifts in precipitation patterns. These findings can be used to enhance watershed management strategies in the area.

Summary: The study found that the Taihang Mountain region has experienced an average warming of 0.3 degrees C/decade over the past five decades, with seasonal variations in warming rates. Elevation and latitude were significantly negatively correlated with temperature, but not with the temporal warming trend. The Z value was significantly negatively correlated with percent forestland and positively correlated with GDP, suggesting the impact of economic development and afforestation on temperature changes in the region.

Summary: Investigating the trends and sensitivity of reference evapotranspiration (ETo) to meteorological variables is important for water resource management and climate variability analysis. This study analyzed a 17-year dataset from a Mediterranean climate region and found a downward trend in ETo in November, as well as downward trends in solar radiation and rainfall during autumn. Other meteorological variables showed an upward trend, with specific humidity and wind speed having the highest and lowest contribution to ETo trends, respectively.

Summary: This study analyzed rainfall trends in Syria and found that most stations showed a decreasing trend in rainfall. While there was a slight increase in rainfall during the fall period, significant decreases were observed in winter and spring. This will result in water scarcity in the country. These findings align with predictions from the Intergovernmental Panel on Climate Change (IPCC) regarding decreasing rainfall in the Mediterranean and southern Asia regions.

Summary: This study investigates the trends of rainfall and temperature in agricultural regions of Turkey from 1969 to 2020. The findings suggest that there is no significant trend in monthly rainfall according to the Mann-Kendall test, but both innovative approaches show a decreasing (increasing) trend in November (September) for most stations. As for temperature, there is a general increasing trend or no trend throughout the year, except for April. The results also reveal that the seasonal variability of rainfall is complex and persistent in all agricultural regions. The irregular changes in rainfall and rising temperatures have negatively affected crop yield and may require more irrigation.

Summary: In this paper, we propose an effective technique for semantic segmentation using Depth-to-Space Net (DTS-Net), which is a sub-pixel convolutional neural network. The technique combines depth-to-space image reconstruction with a mask enhancement filtration technique based on multi-label classification. We also introduce a deep network and a lightweight network for real-time semantic segmentation, achieving better performance compared to state-of-the-art methods that rely on encoder-decoder architectures.

Summary: This study investigates the flow characteristics of natural grassed canals and analyzes the effects on Manning coefficient and specific energy. The study found that the Manning coefficient increased with an increase in energy and momentum coefficients, and the un-grassed canal showed a higher momentum coefficient than the grassed canal. Different modeling programs were used to create empirical formulas for predicting values, with gene expression programming identified as the best modeling program.

Summary: One of the most prevalent and serious issues in developing countries is the lack of adequate space for waste disposal. This study aims to address this problem in Al-Gharbia Governorate, Egypt, by determining optimal landfill locations using multi-criteria decision-making techniques. The results show that suitable areas are limited and mainly concentrated in the northeast, central, and northern regions, while a significant portion of the governorate is unsuitable due to agricultural nature, high population density, and elevated groundwater levels.

Summary: In this paper, a modified and lightweight deep object detection model based on the YOLO-v5 architecture is proposed, which can detect objects of various sizes. It employs a multi-scale mechanism to learn deep discriminative feature representations at different scales and automatically determine the most suitable scales for object detection in a scene (i.e., vehicles in this case). Experimental results demonstrate significant improvement in precision compared to the original YOLO-v5 architecture.
