Sources of contamination in a subsurface environment are petrol, diesel fuel, gasoline at oil refineries, underground storage tanks, transmission pipelines, and different industries. The permeable reactive barrier (PRB) is promising technology to remediate groundwater in-situ. In this study, synthetic samples containing toluene treated three reactor columns by biological processes. PRB-1 consis...

Oak wilt, caused by Ceratocystzsfagacearum (T.W. Bretz) J. Hunt, is probably the most destructive disease of oak trees (Quercus species) in the United States, and is currently causing high mortality at epiphytotic proportions in central Texas. The serious potential for damage prompted an increase in federal funding within the past fifteen years for new oak wilt research. New research developmen...

Laboratory experiments were performed in the wave flume of Laboratorio di Idraulica e Costruzioni Marittime Università Politecnica delle Marche (Ancona, Italy) to study hydrodynamic performance coastal protection structures made a new type geotextile sand containers (GSCs). Such are used as softer and flexible alternatives traditional hard defenses concrete or rubble mound material. The GSC can...

The effectiveness of six different reburial systems was investigated by means a monitoring station installed on part approximately 110 square meters mosaic, defined as basilica thermarum in the Southern Baths ancient city Perge. scope study covers consisting only soil filling tessellatum layer; sand geotextile laid surface; and gravel, respectively pozzolana surface, finally, 5 cm sand, geotext...

Unexpected differential tidal pressures occurred during construction of a 62 Ha reclamation area at Townsville Port. The reduction in flows through new rock wall structure was conjunction with installation geotextile membrane. Tidal began to displace the and cover rock. This paper discusses tide data collected various stages how it used for estimating progressive differentials. These estimates ...

Designing and building structures infrastructures with alternative environmentally friendly materials is, nowadays, an important step towards a more sustainable society. Recycled Construction Demolition (C&D) have been considered as in different civil engineering applications, such unbound pavement layers structural embankments, which geosynthetics are also frequently applied. If the durability...

This paper presents the study of a mixed porous media composed of expanded perlite and a nonwoven needle-punched geotextile used to reduce the suspended solids load and concentration in urban runoff. Laboratory procedures were designed to quantify the suspended solids removal efficiency and variation in time of filtration rate. Different grain-size distributions of expanded perlite, diverse sus...
