Soil erosion model SERT-2014© SAGA v1.0

Abstract

[ES] El modelo SERT es un método de simulación numérica de base semi-física que permite predecir las tasas promedio de escorrentía, erosión del suelo por regueros y zonas de arroyada, la redistribución espacial del suelo y la exportación del suelo erosionado a los cursos de agua semipermanente o permanente. Este modelo ha sido diseñado para cuencas muy pequeñas (< 1 km2), pequeñas (1–5 km2) y medianas (5–50 km2) sin presencia de cursos de agua permanentes (p.ej., arroyos y ríos). El modelo utiliza comandos de tipo SIG programados para calcular los factores de balance de la escorrentía acumulada y del suelo/sedimento removilizados, así como para el cálculo de la redistribución espacial de ambos componentes a lo largo de las laderas. Los procesos que tienen lugar en el leche de los cursos de agua permanentes y los taludes no se modelizan. El programa SERT-2014© SAGA v1.0 se divide en tres módulos independientes: i) hidrología (SERT-Hydro), ii) erosión del suelo (SERT-Eros), y iii) redistribución y exportación del suelo (SERT-Redis). El módulo de hidrología se basa y comparte la mayoría de las ecuaciones del modelo de balance hídrico DR2-2013© SAGA v1.1 (López-Vicente et al., 2014, Environmental Modelling & Software 62, 11-21; http://digital.csic.es/handle/10261/101825) y en su programa (http://digital.csic.es/handle/10261/93543). El programa SERT-2014© SAGA v1.0 requiere 24 parámetros de entrada (14 a resolución mensual y 10 sin variación temporal) y considera las variaciones espaciales y temporales de los parámetros de lluvia (intensidad y cantidad), infiltración/saturación, vegetación, prácticas de manejo y laboreo, y del área contributiva. El programa genera 15 parámetros de salida, entre mapas y tablas. El programa se ha desarrollado para la aplicación de tipo SIG SAGA© 2.0.8 para Microsoft Windows (32 y 64 bits) y también para LINUX. Los módulos SERT-Hydro y SERT-Redis incluyen 8 algoritmos de flujo acumulado ponderados (4 flujo único y 4 de flujo múltiple) que pueden simular 15 patrones espaciales diferentes de escorrentía y de redistribución del suelo desagregado. El programa incluye un paquete estadístico de los principales parámetros de salida. Las librerías de los tres módulos se han desarrollado en lenguaje C++ y el código del programa SERT-2014© SAGA v1.0 está registrado y protegido ante notario (número 2753/2014, fecha: 17 de diciembre de 2014, lugar: Madrid, España).

[EN] The SERT model is a semi-physically-based approach to predict average rates of runoff depth, soil erosion in rill and interrill areas and sediment redistribution and yield in very small (< 1 km2), small (1–5 km2) and medium (5–50 km2) size catchments without permanent streams (e.g. creeks and rivers). The model uses programmed GIS commands to calculate the water and sediment balance factors and also the cumulative upstream runoff and relocation of sediments along the hillslopes. The processes that take place on the riverbed and river talus are not contemplated. The SERT-2014© SAGA v1.0 software is divided into three independent modules: i) hydrology (SERT-Hydro), ii) soil erosion (SERT-Eros) and iii) soil redistribution (SERT-Redis). The SERT-Hydro module has the conceptual basis and most of the equations of the DR2-2013© SAGA v1.1 water balance model (López-Vicente et al., 2014, Environmental Modelling & Software 62, 11-21; http://digital.csic.es/handle/10261/101825) and software (http://digital.csic.es/handle/10261/93543). The SERT-2014© SAGA v1.0 software requires 24 inputs (14 at monthly resolution and 10 without temporal variability) and it considers the spatial and temporal variations in rainfall intensity and depth, soil saturation, vegetation, tillage practices and upslope contribution factors. It generates 15 different outputs between maps and tables. It has been developed for the open-source SAGA© 2.0.8 GIS software for Microsoft Windows (32 and 64 bits) and also for LINUX. The SERT-Hydro and SERT-Redis modules includes the 8 weighted Flow Accumulation Algorithms (4 single-flow and 4 multiple-flow) that can simulate 15 spatial patterns of runoff and sediment redistribution. It includes a statistical package for the values of the main outputs. Module libraries are developed using C++ code and the script of the SERT-2014© SAGA v1.0 software was registered by a public notary (# 2753/2014, date: 17 December 2014, place: Madrid, Spain).

[ES] El programa informático SERT-2014© SAGA v1.0 es la primera versión programada (junio 2014) de la tercera versión (junio 2014) del modelo con base SIG Soil Erosion and Redistribution Tool (SERT). La primera versión se presentó en diciembre de 2007 (dentro del proyecto de tesis doctoral del Dr. López-Vicente) y la segunda versión en 2012 (López-Vicente et al., 2013, Agricultural Water Management 125: 1-12; http://digital.csic.es/handle/10261/75609).
