Method for evaluation of depth of wetting in residential areas / Kenneth D. Walsh in Journal of geotechnical and geoenvironmental engineering, Vol. 135 N°2 (Février 2009) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 135 N°2 (Février 2009) . - pp. 169–176 Titre : Method for evaluation of depth of wetting in residential areas Type de document : texte imprimé Auteurs : Kenneth D. Walsh, Auteur ; Craig A. Colby, Auteur ; William N. Houston, Auteur Année de publication : 2009 Article en page(s) : pp. 169–176 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Expansive  soils  Subsurface  flow  Soil  suction  Unsaturated  soils  Residential  location  Colorado  Irrigation  Urban  areas Résumé : Field sampling was performed at a number of residential structures in the Denver metropolitan area for the purpose of assessing the extent of wetting below residential structures after construction and commencement of landscape irrigation. Total suction measurements using filter paper methods were undertaken on undisturbed samples. A similar data set from sites without previous development or irrigation was used to estimate the suction profile before the imposition of residential construction and landscape irrigation. Comparison of the postdevelopment profile measured at the residential structures to the predevelopment profile estimated using a site-specific procedure was used to assess the depth of wetting at each structure. Cumulative probability curves are presented for the depth of wetting arising from common residential landscape schemes and site drainage for the Denver area. The Denver-area data set was used to develop a method for assessment of depth of wetting. This method can be used to assess depth of wetting from residential development for other regions having different climatic conditions and landscape practices.
