The objective of this paper is to describe an autoregressive regression framework with respect to metered sewer flow and simultaneous rainfall data series. The main purpose is to produce more reliable estimates for rain derived inflow and infiltration RDII characteristics in a sanitary sewer basin. The discussion is centered at three specific points: 1 a justification for an autoregressive erro...

As one of major underground pipelines, sewerage is an important infrastructure in any modern city. The most common problem occurring in sewerage is leaking, whose position and failure level is typically identified through closed circuit television (CCTV) inspection in order to facilitate rehabilitation process. This paper proposes a novel method of computer vision, morphological segmentation ba...

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Impact of dry weather discharges on annual pollution from a separate storm sewer in Toulouse, France. • Dry weather discharges from storm sewers have an impact on annual pollution load. • The more urbanized the outlet is, the more important the pollution i...

INTRODUCTION The aim of this study was to determine the problems encountered during investigations into causes of death in corpses found in wells, sewer systems and pits, and to seek solutions to the problems. In fact, wells, sewer systems and pits have some common characteristics which may cause the problems. They contain water, have a hypoxic/anoxic environment and prevent corpses from being ...

Urban pluvial flooding occurs when the capacity of sewer networks is surcharged due to large amounts runoff produced during intense rain events. Rapid urbanization processes and changes in climate increase these events frequency. Effective sustainable approaches for reduction urban floods are necessary. Although several gray, green hybrid measures have been studied, influence network structure ...

In order to investigate the characterization of runoff in storm sewer from various urban catchments, three monitoring systems at different spatial scales have been installed separately. They have been held since July 2010 in urban area of Beijing (China). The monitoring data revealed that chemical oxygen demand (COD), total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP), and...
