Information theory applied to evaluate the discharge monitoring network of the Magdalena River
The acquisition of good hydrologic information is an important issue in water management since it is the basis of decisions concerning the allocation of water resources to different users. However, sufficient data are often not available to describe the behaviour of such systems, especially in developing countries, where monitoring networks are inappropriately designed, poorly operated or are ...

MCerts: The Fuller Picture
The introduction of MCerts for self-monitoring of discharge flows focused attention on areas of flow measurement that had been long overlooked. But the story is far from complete. WRc’s Andy Godley reports. It is more than two years since the Environment Agency’s MCerts scheme for self-monitoring of discharge flows became mandatory. This meant that those discharging treated water to the ...

Case study - Continuous discharge monitoring in Mecklenburg - Germany
The Wallensteingraben was originally constructed as a channel and is almost 20 km long. In the context of implementing the European Water Framework Directive, goals include improving ecological passability. At the same time a measurement site for the continuous monitoring of discharge quantities was installed. Products used include OTT SLD, OTT CBS and OTT LogoSens. Monitoring Solution ...

Project - Lobsterman’s Wharf
Lobsterman’s Wharf is a seasonal restaurant serving seafood and meat dishes. Fried as well as grilled food is on the menu. There is also a 14-room inn as part of the property. All kitchen wastewater flows through an automatic grease removal unit prior to entering an existing grease trap. Sanitary and kitchen flow enters a pump station that pumps the influent to the treatment plant located ...

Hill Biscuits, Ltd. - Case Study
Wastewater issues from solidified palm oil combined with flour resulting in high operating costs and surcharges. Plant had conventional grease trap to capture the fat. The two sections of the existing grease trap were isolated and the primary section utilised as the influent source via a dip tube. A 100 GPM Fogbuster Jr, with automated control system was installed with a low shear Moyno pump for ...

Similarity, difference and correlation of meteorological and hydrological drought indices in a humid climate region – the Poyang Lake catchment in China
Based on the estimation of standardized precipitation–evapotranspiration index (SPEI) and standardized runoff index (SRI), this study investigated the variability and correlation of hydrological drought and meteorological drought in a humid climate region – the Poyang Lake catchment in China. Results indicate that the occurrences of hydrological droughts in the catchment are different from ...

No Nonsense Guide to Wastewater Treatment
Thanks to Dendra Best at Wastewater Education - She encouraged and supported us to put together this Webinar in which we discuss how our ASP-Con is used to monitor rogue discharges, reduce aeration costs by up to 50%, increase plant control and throughput, size blowers etc etc etc. Please hear from our supported Paul Banfield of Veolia and Mikel Goldblatt of Solenis on how these are all achieved ...

Lagoon Discharge Flow Monitoring - Case Study
Open Channel Flow Monitoring without a Flume or Weir Township operators liked the Greyline AVFM 5.0 datalogger reporting system where formatted flow reports (total, minimum, maximum and average) could be downloaded automatically to a USB memory stick without carrying a laptop to the site. The Township of South Glengarry in Eastern Ontario discharges continuously from their 72,000 m3 sewage ...

Online discharge measurement with horizontal doppler-flow sensor
Background The regional authority responsible for the barrages in the Free State of Saxony is in charge of the water management of the Rötha. Reservoir. This reservoir is situated close to the river Pleiße, from which the water is led over a weir into the reservoir.. Knowledge about the inflows of the reservoir is important for the water management there. So far, the rate of flow at the ...

Influence of local calibration on the quality of online wet weather discharge monitoring: feedback from five international case studies
This paper reports about experiences gathered from five online monitoring campaigns in the sewer systems of Berlin (Germany), Graz (Austria), Lyon (France) and Bogota (Colombia) using ultraviolet–visible (UV–VIS) spectrometers and turbidimeters. Online probes are useful for the measurement of highly dynamic processes, e.g. combined sewer overflows (CSO), storm events, and river ...

Comparing grey formulations of the velocity-area method and entropy method for discharge estimation with uncertainty
Two methods, namely the velocity-area method and the entropy method, for assessing with uncertainty discharge measurements at gauged river sites are analysed and compared; uncertainty is represented through the grey number technique. Two different approaches for the ‘greyification’ of both methods are presented. In the first approach, the uncertainty affecting each measurement ...

Efficiency of a turbidity-based, real-time control strategy applied to a retention tank: a simulation study
This paper compares several real-time control (RTC) strategies for a generic configuration consisting of a storage tank with two overflow facilities. Two of the strategies only make use of flow rate data, while the third also introduces turbidity data in order to exercise dynamic control between two overflow locations. The efficiency of each strategy is compared over a wide range of system ...

A grey-based method for evaluating the effects of rating curve uncertainty on frequency analysis of annual maxima
A grey-based technique for characterizing the rating curve uncertainty due to discharge measurement errors and its effect on flood frequency analysis is here presented. On the basis of river stage and discharge measurements, the grey parameters of the rating curve are estimated by using a grey non-linear regression. Commencing with this grey rating curve and a set of annual maximum stages, we ...

Model-based monitoring of stormwater runoff quality
Monitoring of micropollutants (MP) in stormwater is essential to evaluate the impacts of stormwater on the receiving aquatic environment. The aim of this study was to investigate how different strategies for monitoring of stormwater quality (combining a model with field sampling) affect the information obtained about MP discharged from the monitored system. A dynamic stormwater quality model ...
