Abstract
The drywell is an on-lot drainage system, which is composed by an excavation in the soil lined with a perforated piped and gravel at the bottom and sides. There are many models for on lot systems dimensioning, which were initially developed for agriculture areas or for simulation of water percolation in porous media, thus, they are not fully optimized for small areas like urban lots. This article proposes a model for dimensioning drywells, which is based on physical and hydrological characteristics of the installation site. It was developed using the analogy between water flow in soil and the heat flux in media solids. Results obtained with the proposed model were statistically similar (p>0,05) to those obtained with experimental data.
期刊介绍：
Journal of Urban and Environmental Engineering (JUEE) provides a forum for original papers and for the exchange of information and views on significant developments in urban and environmental engineering worldwide. The scope of the journal includes: (a) Water Resources and Waste Management [...] (b) Constructions and Environment[...] (c) Urban Design[...] (d) Transportation Engineering[...] The Editors welcome original papers, scientific notes and discussions, in English, in those and related topics. All papers submitted to the Journal are peer reviewed by an international panel of Associate Editors and other experts. Authors are encouraged to suggest potential referees with their submission. Authors will have to confirm that the work, or any part of it, has not been published before and is not presently being considered for publication elsewhere.
