Comparative Evaluation of Infiltration Capacity in High-Andean Soils: Analysis in the Aláquez and Pumacunchi Rivers, Cotopaxi Province
摘要
Water infiltration in the soils of the Cotopaxi province is of great importance for water management in high-Andean areas. Thus, the Double Ring and Porchet techniques were used to evaluate the infiltration capacity of the Aláquez and Pumacunchi Rivers, whose areas have volcanic features and highly variable texture and composition. The results show that the infiltration capacity in both microbasins varies greatly due to the soil in each area, in addition to the potential influence of human activities occurring around these study areas. The Double Ring method found that the Pumacunchi River had the highest infiltration rate of 315 mm/h, while the Aláquez River had the highest infiltration rate of 138 mm/h. This indicates that the soil in the Pumacunchi River has a greater infiltration capacity and is more permeable, allowing water to filter through more rapidly both vertically and horizontally. On the other hand, the Porch method, which is simpler to perform, effectively validated the greater permeability in the soils of the Pumacunchi River, reaching 410 mm/h, while the Aláquez River had an infiltration capacity of 61 mm/h. It is important to mention that both methods were carried out within the recommended duration, which was 180 min, with initial data collection every 1 min, then every 5, 10, 15, and 30 min, respectively. Therefore, the results underscore the need for strategies tailored to each area, aimed at optimizing water management based on soil characteristics.
