Fog is a resource that has been used to obtain water worldwide, but a structure that represents a greater capture of this resource has not been implemented. Objective. To measure the efficiency of horizontal rain collection represented in l / m2-day of two structures with natural forms (a tree simulating the crown of a pine and a geodesic dome of frequency 4v); compared to the conventional model (screen). Materials and methods. The design and construction of the trappers was carried out accompanied by a rain gauge, where daily measurements were taken of the water collected by each structure for 10 months, then the direct rainfall was subtracted from the total rainfall to find only the water that comes from the fog. With the data obtained, an exploratory and graphic analysis was performed. Confirmatory statistical tests were also applied through the use of the R software to determine which structure has the highest efficiency. Results.The 4v geodesic dome and the tree collected on average 1.94 l / m2-day and 1.64 l / m2-day respectively and the conventional structure captured 0.97 l / m2-day. Conclusions. The structures with designs based on natural forms have a greater efficiency of collecting horizontal rainesAcceso abiertoCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráPrecipitaciónAgua lluviaAgua - AlmacenamientoAnálisis de aguaCiclo hidrológicoLluviainfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAcces
