A scientific drainage system to catch the storm water is a long term ambition of the society, especially in cities. Increasing development activities have called badly for the necessity of discharging runoff safely in to environment. It is often being happened that over densification and modification of undeveloped land is also resulting increased flow with increased pollution. Irrespective of the city, most of our city’s face will be fractured, if a heavy storm with high run off is hit, due to improper drainage facilities. Most of our existing storm water drains are in dilapidated stages and not working properly, losing self cleansing, no proper maintenance, and incorrect design without any scientific base, the bottlenecks go so on. A proper storm water design means a proper knowledge of a collection of data like understanding the precipitation data clearly, know the infiltration indices, concentration time, intensity of rainfall, runoff details etc. It appears most of the time that many of the data may not be correct and thus the design of the storm water drains with these so called data will be a catastrophe. The present study is the work done for the drainage design in Palayam area of Calicut City in Kerala, India where the excess runoff is really a threat to the environment due to dense population. |
