Argote-Sanchez Juliana M. Lozano-Santa Aldemar Reyes-Trujillo Ingeniería Andisols Hydrus 2D Moisture retention In the watershed Centella , located in the upper river basin of the Dagua - Valle del Cauca, in nine farms with association coffee - banana, coffee - guamo, cane panelera and pastures, the water regulation capacity of the soil was studied by means of humidity retention curves obtained in the laboratory and by modeling its hydrophysical properties in Hydrus 2D. Properties such as texture, bulk density, porosity, organic matter, hydraulic conductivity, infiltration and humidity were determined. Subsequently, moisture retention curves were simulated using the hydraulic models of Van Genuchten, Brooks and Corey, Van Genuchten modified and Kosugi, evaluating the average errors and the dispersion of the data. Agreed to the results it is possible to point out that the soil under study has a high capacity for moisture retention (>18%), consequence of the high content of clays (>41%) and organic matter (>5%), characteristics of the Andisols of the Valle del Cauca. Finally, the best fitting model was compared statistically with the data of the curves obtained in the laboratory, finding that Van Genuchten and Van Genuchten models modified, are the most appropriate for obtaining the retention curves from the hydrophysical properties since they presented a lower mean error (ME) with a value not higher than -0.11 cm3 / cm3 and a value of the square root of the mean square error (RMSE) less than 0.11 cm3 / cm3. 2019 artículo científico 0123-3033 https://www.redalyc.org/articulo.oa?id=291361226009 https://www.redalyc.org/journal/2913/291361226009/ https://www.redalyc.org/journal/2913/291361226009/html/ https://www.redalyc.org/journal/2913/291361226009/291361226009.epub https://www.redalyc.org/journal/2913/291361226009/movil 10.25100/iyc.v21i1.7670 en http://www.redalyc.org/revista.oa?id=2913 Ingeniería y Competitividad application/pdf Universidad del Valle Ingeniería y Competitividad (Colombia) Num.1 Vol.21 |
