The essential requirement for designing of Storm Water Drainage system is the proper estimation of storm runoff to downstream drains or the point of disposal. It has a bearing on optimizing the cost of infrastructure as well as its performance. […]

In storm water drainage system design, estimation of runoff from the tributary catchment reaching various inlets of the drain is important. This can be estimated if Intensity Duration Frequency (IDF) curves are available. The IDF curve is drawn based on […]

Important factors responsible for present status of poor urban drainage system in India 1.The natural drainage systems in most of the cities are in jeopardy, and the problem of flooding is worsening with time due to non-availability of properly engineered […]

Using this runoff data, the storm water drains should be designed following the aspects of design as mentioned in CPHEEO manual Chapters 5, 6 & 7. Reduction in storm runoff by constructing retention/detention ponds / Rooftop rainwater harvesting etc. as […]
