Steel pipe umbrellas have been used to tunnel in difficult conditions or in weak rock masses and/or soils. Despite
the large number of applications around the world, there are still some doubts concerning how pipe umbrellas behave under
loading when the tunnel face advances. For this reason, a scale laboratory model of pipe umbre...
A wide variety of structural best management practices (BMPs) has been developed in the last few decades to control erosion-related problems at construction sites. Even though many BMPs exist to control erosion and sediment accumulation, there is very little research on their performance and this is even more pronounced when considering the performance ...
View ArticleFinding explicit solutions to the partial differential equations governing the infiltration phenomenon tend to be a challenging issue. On account of such complexity, researchers have proposed algebraic equations to model this phenomenon. This paper deals with the solution of the general three-parameter infiltration equation, which is an implicit equatio...
View ArticleThis manuscript aims proposing a methodology for correlating soil porosity to the respective geological units using geostatistical analysis techniques, including interpolation data by kriging. The site studied was in Lorena municipality, Paraíba do Sul Valley, southeastern Brazil. Specifically all studies were carried out within an area of 12...
