Abstract

The objective of this research was to assess the use of unsaturated water flow in terms of soil water evaporation, which was determined by evaluating some soil hydraulic parameters in different soil textures. The results show that the predicted values of these parameters, which were obtained through inverse modeling with the HYDRUS-1D software and depend on the change of the volumetric water content, exhibited a significant agreement with the measured values from laboratory or field simulation data for soil water evaporation at 5. 10. 20. and 45 days of measurement. At the same time, inverse simulation was conducted on soil hydraulic parameters obtained from a 5-day laboratory soil evaporation period to predict field infiltration values and water retention curve, which showed a significant agreement with measured values for all soil textures.

利用HYDRUS-1D反演模型预测土壤水分蒸发的部分水力参数

本研究的目的是从土壤水分蒸发的角度评估非饱和水流的使用，这是通过评估不同土壤质地的一些土壤水力参数来确定的。结果表明，这些参数的预测值是用HYDRUS-1D软件通过逆建模获得的，取决于体积含水量的变化，与实验室或现场模拟数据中5时土壤水分蒸发的测量值表现出显著的一致性。10.20。以及45天的测量。同时，对从5天的实验室土壤蒸发期获得的土壤水力参数进行了反模拟，以预测田间入渗值和保水曲线，这与所有土壤质地的测量值都显示出显著的一致性。

期刊介绍： Colombia Forestal Journal publishes original manuscripts on themes of the forest field and various aspects of natural resources and the environment, which are discriminated in the categories of research article, review, reflection and technical notes of agreement with the stipulations of COLCIENCIAS for scientific publications. According to the classification of scientific areas of the Organization for Economic Cooperation and Development (OECD), Colombia Forestal Journal belongs to the large area of Agricultural Sciences (4), Agriculture, Forestry and Fisheries (4A) and to the discipline Forestry (4A02). Since its creation in 1978, the journal has been edited and published by the Francisco José de Caldas District University with headquarters in Bogotá. The quality of the content of the journal has been strengthened with the collaboration of national and international external evaluators in a double blind arbitration system and the dissemination has been extended by publishing manuscripts in a language different from Spanish and with inclusion in bibliographical databases such as Scopus. , DOAJ, Scielo, Redalyc, Ebsco, CAB Abstracts of CAB International, Forestry Abstracts, Ulrich''s, Latindex, Publindex. Likewise, it has academic profiles at Mendeley, Academia and Researchgate. The articles that are submitted to Colombia Forestal Journal must be original and unpublished and have not been postulated in other journals.
