Identification and modelling of dry weather processes in gully pots

摘要

This paper presents the results of a monitoring and modelling programme, carried out to study the processes occurring in gully pots during dry weather. The monitoring programme involved estimation of the change in gully pot liquor quality, under field and laboratory conditions. The contents (i. e. liquor and sludge) of pots draining five different types of roads were monitored over dry periods in the winter and summer. A bench scale study was carried out to study the influence of temperature variations and sludge digestion by-products on gully liquor quality.
