Modelling Impact of Extreme Rainfall on Sanitary Sewer System by Predicting Rainfall Derived Infiltration/Inflow
Extreme climate events are becoming more intense in Melbourne in recent years. This increasing intensity of excessive rainfall has an adverse effect on the sewer network by causing sewage overflow hazards. Extreme rainfall events increase flow into the sewer system, both directly (inflow) and through infiltration into sewer. As a result of this Rainfall Derived Infiltration and Inflow (RDII), S...
متن کاملHyetograph Simulation of High-Intense Rainfall Events
Hyetographs (rain-intensity curves) picture the time distribution of point rainfall and are important for hydrologic and hydraulic design issues. In the study of soil erosion, specifically on movement of soil particles by raindrop impact, kinetic energy is a commonly suggested indicator of the raindrop's ability to detach soil particles from the soil mass. The kinetic energy of raindrops can be...
متن کاملIntense Rainfall Events over the West coast of India
The west coast of the Indian peninsula receives very heavy rainfall during the summer monsoon (June-September) season with average rainfall over some parts exceeding 250 cm. Heavy rainfall events with rainfall more than 15 cm day −1 at one or more stations along the west coast of India occur frequently and cause considerable damage. out during the monsoon season of 2002 to study these events. T...
متن کاملLayout and size optimization of sanitary sewer network using intelligent ants
The incremental solution building capability of ant algorithm is exploited in this paper for the efficient layout and pipe size optimization of sanitary sewer network. Layout and pipe size optimization of sewer networks requires that the pipe locations, pipe diameters and pipe slopes are optimally determined. This problem is a highly constrained mixed-integer nonlinear programming (MINLP) probl...
متن کاملShort-term forecasts and scaling of intense events in turbulence
Large fluctuations in complex systems from earthquakes to financial markets, though infrequent, are particularly important because of their disproportionate impact. Our ability to forecast them is quite poor at present. Large fluctuations occur also in intermittent features of turbulent flows. Some dynamical understanding of these features is possible because the governing equations are known a...
