Green roofs as a solution to inundations problem in urban environments

This research was carried out using mathematical models in order to compare the runoff from an urban planning with handmade tiles roofs in actual conditions, with one where structures or storage devices and water retention in houses, yards are used, parcels, streets and housing complexes in general....

Se seleccionó una zona de estudio en el Estado Lara (Venezuela), en el municipio Palavecino, en las inmediaciones de la Quebrada Tabure, considerando los techos verdes desde el punto de vista de reductores de escorrentía. Se elaboró una aplicación llamada “TechosVerdes.py” en el programa de licencia libre Python, con aproximadamente 4600 líneas de código para calcular los hidrogramas de los techos, patios, calles y áreas verdes, basándose en un mosaico creado con imágenes tipo raster en el programa Quantum Gis. La investigación se basó en la comparación directa de trece escenarios hipotéticos, donde se utilizó techos verdes y adicionalmente, tanques de almacenamiento y brocales, con un escenario original en condiciones actuales, sin alteraciones. Se obtuvo como resultado en loshidrogramas calculados para los escenarios hipotéticos, que el caudal pico disminuye, achatándose el hidrograma Universidad Centroccidental Lisandro Alvarado - Decanato de Ingeniería Civil 2018-07-24 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo científico de investigación original application/pdf https://revistas.uclave.org/index.php/gt/article/view/1247 10.13140/RG.2.1.3524.4405 Gaceta Técnica; Vol. 14 No. 1 (2015): July-December; 9-21 Gaceta Técnica; Vol. 14 Núm. 1 (2015): Julio- Diciembre; 9-21 Gaceta Técnica; v. 14 n. 1 (2015): July-December; 9-21 2477-9539 spa https://revistas.uclave.org/index.php/gt/article/view/1247/550
