Estudio sedimentológico en la cuenca de la quebrada La Floresta en los municipios de Pailitas y Tamalameque, departamento del Cesar, Colombia

Abstract

Introduction:  La Floresta brook is located between the municipalities of Pailitas and Tamalameque, has an extension of 13,500 hectares, where granulometric studies, humidity and sediment volume estimation contributed by the basin through the model EROSUP-U.

Objective: In order to quantify the sedimentological contribution and classify the soil type based on AASTHO and USC.

Methodology: 84 samples were collected, each 10mts and 15mts, following the methodology proposed by the Federal Electricity Commission of Mexico.

 Results: The volumetric estimation, applying the universal equation of soil loss (EUPS), establishes that the sedimentological contribution of the brook is of 4,944,679,344.77 m3 / year; the soil was classified into four (4) groups (A-1-a, A-1-b, A-2-4, A-2-6), the most representative is A-1-a with 84.52% of the samples analyzed.

Conclusions: La Floresta brook has a wide granulometric variability of sediments, with a greater proportion of gravel, coarse sand and fine sand, with or without well-graduated fine material, with a predominance of gravels and a sedimentological contribution of 4,944,679,344.77 m³ / year.
