Abstract: Energy access is a critical factor for economic development and social progress, particularly in rural areas of developing countries like Ethiopia. This study aims to identify and prioritize suitable hydropower sites along the Furfuro River using the analytical hierarchy process (AHP), a multi-criteria decision analysis (MCDA) method. Five key criteria were considered: power, discharge, head, accessibility, and distance. To evaluate the relative significance of these factors, a pairwise comparison matrix was created. Normalization and critical weight calculation were performed to determine the weight of each criterion. The consistency of the pairwise comparison matrix was evaluated using the consistency ratio (CR), which was found to be acceptable. The site with the highest suitability index was ranked the most suitable for hydropower development. The findings of this study provide valuable insights for decision-makers in prioritizing hydropower development in the region, reducing reliance on traditional, harmful energy sources, and improving the quality of life for local communities along the Furfuro River. By considering multiple factors and employing the Analytic Hierarchy Process, this research contributes to sustainable energy planning and resource management.

Abstract: This article highlights contemporary difficulties including new salt leaching technologies for reducing salinity in cotton fields. Also, the impact of dividing fields into floors with a check mark (check mark) on salt leaching requirements in laser leveled areas. Field studies were carried out in five different research fields from February to March 2024 in compliance with specific methodological requirements. The experiments were carried out on farms in the Urgench area of the Khorezm region, where laser leveling work was finished in early 2024 while considering soil salinity and mechanical properties. The soil samples were collected from the research sites before and after the salt leaching period to establish the success of the process, the level of salinity, and the mechanical composition of the soil. Samples were analyzed in a laboratory to determine the level of soil salinity and the amount of salts (anions and cations - Cl-, HCO3-, Sa+2, and Mg+2), and the mechanical composition of the soil was assessed using the Kachinsky method based on the water-physical properties. The results showed that high-quality field leveling (±2 cm) with laser levelers improves salt leaching quality, maintains uniform water depth, and prepares the region for seed planting, as demonstrated in a 16-hectare experimental field. However, other factors also affect this, such as the depth of plowing the field, the intensity of water entering the field, the amount of water consumed, and the availability of water during irrigation (day and night).
