High frequency temperature measurements along the in-sewer cable create a detailed representation of temperature anomalies due to illicit discharges. The detection limits of the monitoring equipment itself are...

Voor het ontwerp van rioolstelsels wordt gebruik gemaakt van hydrodynamische modellen. Met deze modellen worden stelsels zo ontworpen dat alleen bij buien die eens per 2 of 5 jaar optreden niet al het water wordt afgevoerd. Door deze modellen wordt de waterbeweging in de riolering goed beschreven en het is goed mogelijk om te bepalen hoe vaak er...
