Growing media in green infrastructure (GI) designed for stormwater management plays a critical role providing hydrological benefits. However, sediment deposition by urban can cause clogging and reduce the infiltration capacity. This study introduces new approach to characterise impact of GI that uses fluorescent tracer particles. Results are compared two contrasting growing media: Grey Green Su...

Iron- and manganese-depositing bacteria occur in many soils and all water systems, and their biogenic depositions of ochre in technical systems may cause severe clogging problems and monetary losses. "Candidatus Viadribacter manganicus" is a small coccoid, iron- and manganese-depositing bacterium isolated from the Lower Oder Valley National Park, Germany.

Collection of storm water runoff and forcing it into the groundwater is the need of the hour to sustain the ground water table. However, the runoff entraps various types of sediments and other floating objects whose removal are essential to avoid pollution of ground water and blocking of pores of aquifer. However, it requires regular cleaning and maintenance due to problem of clogging. To evalu...
