Summary: This study developed a comprehensive database of dams in Indonesia, including three times more dams than reported in Indonesia's national database. The database provides information on the geographical coordinates, physical characteristics, and uses of each dam. The aim is to assist hydrological and socio-ecological research in Indonesia.

Summary: Infrastructure-induced fragmentation of riverine ecosystems has created a need for more effective aquatic restoration efforts globally. Past fragmentation assessments have focused on large dams, neglecting the contributions of road crossings and small irrigation structures. This study found that road crossings have a similar impact as large dams on fragmentation, while small irrigation structures have an even greater impact. These findings highlight the importance of considering factors beyond dams in restoring connectivity for aquatic biota.

Summary: Mountainous regions are hotspots for water scarcity and anthropogenic pressure, with substantial uncertainty surrounding future climate and water availability. Scarce, dispersed, and heterogeneous water demand data present a major bottleneck in studying water resource issues. The methodology presented in this paper produces and evaluates high-resolution maps of anthropogenic surface water demand, disaggregated by major types of water demand, to guide decision-making and research in regions like the Andes.

Summary: The supply of water plays a crucial role in regional crop production and food security. The CropWRA model is introduced to assess the satisfaction level of crop water requirements and promote sustainable water management in agriculture. By considering various factors such as DEM, hydrological and climatic data, and crop properties, the model calculates indices related to crop combination, water availability, and accessibility in the Bansloi River basin. Advanced machine learning algorithms are used to calculate the crop water satisfied degree and requirement by incorporating variables like atmospheric conditions, Landsat indices, and energy balance components for soil moisture estimation. The average crop water demand is 1.92 m, with a range of 1.58 to 2.26 m. The CropWSD varies from 17% to 116% due to variations in topography, river system, crop combination, land use, and water utilization. The average crop water satisfied degree is 59%, with 71% of the total area falling between 40% and 60% CropWSD level. The CropWRA model can be applied for sustainable water resource management, irrigation infrastructure development, and utilization of modern technologies.

Summary: This paper uses GIS-fuzzy logic technology to evaluate and rank existing irrigation dams, select the most suitable dam for small hydropower development, and demonstrate feasibility through evaluation of Turkish dams. Additionally, the use of medium-head hydro turbines and optimized grid connection routes are proposed to minimize land expropriation.

Summary: This paper examines the influence of large dams on population growth and agricultural expansion in the United States, finding that dam development leads to a cycle of increasing water consumption. Particularly in the Southwest region, the legacy of dams results in high levels of water consumption and severe water crises.

Summary: Dams and their reservoirs play a significant role in society and the environment, facilitating water resource management while potentially causing adverse impacts related to safety, ecology, and biodiversity. Studies suggest that climate change could exacerbate these impacts, underscoring the importance of continuous monitoring and research on dams.

Summary: Practical solutions to optimise nitrogen use efficiency in modern surface irrigated cotton systems in Australia include adjusting the frequency of irrigation water and reducing nitrogen application rates. A two-year study showed that maintaining a suitable water deficit range during irrigation can increase yield and maintain fiber quality.

Summary: In recent years, there have been continuous investments in new irrigation dams across Africa, resulting in the emergence of new irrigated areas. The ability to irrigate previously rainfed land increases crop production and agricultural value. This study uses crop water modeling to determine the economic benefits of irrigation in the command areas of major African dams built between 2000 and 2015, and evaluates the increase in agricultural revenues resulting from access to water for irrigation.

Summary: Reservoir expansion over the last century has had a significant impact on downstream flow characteristics, but little is known about its effects on the climate. A study implementing reservoir construction in the Community Land Model found that globally, reservoir expansion has limited influence on global temperatures and surface energy balance.

Summary: Micro-dams can effectively reduce water, soil, and phosphorus losses in irrigation systems. Field experiments showed that micro-dams can significantly reduce furrow soil loss and dissolved phosphorus losses, with the reduction depending on discharge and distance.

Summary: Rivers and streams have been altered to meet increasing water demands worldwide, with dams and reservoirs causing severe ecological impacts. However, limited knowledge exists regarding the ecological impacts of different dam purposes and operational schemes on riverine biota. In this study, the effects of dams on river biological communities were assessed, and key ecological responses associated with flow regulation were identified. The results showed that dam purpose and operational scheme influenced ecological changes, with trait-based analyses providing a more detailed understanding of dam-related effects compared to traditional biotic indices. Changes in the biological communities downstream of irrigation dams were primarily related to changes in flow regimes and nutrient concentrations, while hydropower dams significantly affected flow rate and water temperature. These findings are important for river biodiversity conservation strategies and future research directions aimed at mitigating the negative effects of dam operation schemes.

Summary: The sample geometric mean (SGM) is a measure of central tendency with various applications, while the theoretical definition of the population geometric mean (GM) was only introduced recently. The GM can be calculated for many common probability distributions, but lacks a clear physical interpretation. Its estimator SGM exhibits bias and mean square error, depending on sample size, skewness, and kurtosis. Therefore, the justification for using GM in many applications is limited.

Summary: The study reveals an increasing demand for reliable metrics of relative variability for high frequency streamflow series, leading to the introduction of a new C estimator model based on compound distributions theory, which provides more reliable estimates for the relative variability of high frequency streamflow series. These findings contribute to a better understanding of the variability of streamflow in different watersheds.
