Characterization and seasonal dynamics of the ponds located in the flat sector of del Azul Creek Basin

The Flooding Pampa, located in the Pampa region, is characterized by a high number of depressional ponds that are essential for water regulation, aquifer recharge, and as habitats for aquatic species. To understand the seasonal dynamics of three ponds in the flat sector of del Azul Creek basin, nine...

description The Flooding Pampa, located in the Pampa region, is characterized by a high number of depressional ponds that are essential for water regulation, aquifer recharge, and as habitats for aquatic species. To understand the seasonal dynamics of three ponds in the flat sector of del Azul Creek basin, nine seasonal samplings were conducted from 2019 to 2022. Physicochemical variables were measured in situ (transparency, temperature, pH, electrical conductivity, dissolved oxygen), in the laboratory (Kjeldahl nitrogen, total phosphorus, suspended solids), and biological parameters (chlorophyll-a), complemented by trophic index calculations. Satellite imagery and field data were used to estimate the areas of the ponds and their shoreline development index. The ponds exhibited marked surface variations but morphometric stability. Dissolved oxygen and electrical conductivity values were within the typical ranges of Pampean lakes. They showed high levels of nutrients and suspended solids, particularly during summer. Trophic status, based on nutrients, ranged from eutrophic to hypertrophic, although it was underestimated when using chlorophyll-a as an indicator. These findings are crucial for understanding the functionality of these systems and guiding management actions in the context of land use and environmental changes

Con el objetivo de comprender la dinámica estacional de tres cubetas del sector llano de la cuenca del Azul, se realizaron nueve muestreos estacionales durante el período 2019-2022. Se midieron variables fisicoquímicas in situ (transparencia, temperatura, pH, conductividad eléctrica, oxígeno disuelto), en laboratorio (nitrógeno Kjeldahl, fósforo total, sólidos suspendidos) y biológicas (clorofila a), complementadas con cálculos de índices tróficos. Mediante imágenes satelitales y datos de campo, se calcularon las áreas de las cubetas y el índice de desarrollo de costa. Las cubetas mostraron marcadas variaciones de superficie, pero estabilidad morfométrica. Los valores de oxígeno disuelto y conductividad eléctrica coincidieron con rangos típicos de lagunas pampeanas. Presentaron altos niveles de nutrientes y sólidos suspendidos, principalmente en verano. El estado trófico, según los nutrientes, osciló entre eutrófico e hipertrófico, subestimado al emplear la clorofila-a como indicador. Estos resultados son clave para comprender la funcionalidad de estos sistemas y guiar acciones de manejo frente al uso del territorio y los cambios ambientales.
