In urban drainage systems (UDS), a proven method for reducing the combined sewer overflow (CSO) pollution is real-time control (RTC) based on model predictive (MPC). MPC methodologies RTC of UDSs in literature rely computation optimal strategies deterministic rain forecast. However, reality, uncertainties exist rainfall forecasts which affect severely accuracy computing strategies. Under this c...

The principal sources and pathways of pharmaceutical and personal product (PPCP) compounds within an urban drainage system are identified with combined sewer discharges from households and infiltration from landfill/land sludge applications constituting major routeways. Illicit connections, sewer exfiltration and reclaimed domestic wastewaters comprise potentially significant other contaminant ...

The City of Houston has been facing flood problems of a serious nature, some of which occurred in 1989, 1992, 1994, 1998, 2001, and 2003. Tropical Storm Allison in June 2001 created the most extensive urban flood damage in U.S. history ($5 billion). Urban flood problems have repeatedly brought attention to the need for improved urban drainage design and flood prediction, as in the case of the T...

To evaluate the performance of Real Time Control (RTC) urban drainage systems (UDS) a comparison is made with pre-RTC situation, making RTC dependent on functioning th...

Abstract. Increase of population in the current climate change scenario requires to ensure quality groundwater available as well control possible incomes pollution into subsurface system. The objective this work was evaluate and risk infiltration surface contaminants aquifers customizing DRASTIC method including potential flood areas with high pollution. Hydrogeological, hydrochemical isotopic ...

Reducing the hydrologic effects and pollutant loadings from urban drainage systems and restoring aquatic habitats to improve the health of our aquatic ecosystems presents many unique challenges. These challenges can be categorized as technical, institutional, financial, and cultural. This paper will examine each of the challenges and the tools that have and are being developed to overcome them....
