Belgharia is situated near BT Roadand the study area is under Kamarhatimunicipality.Extension of Belgharia :Latitude : 22 39'00'' Longitude : 88 23'00'' . The temperature ranges fromabout 10 to 20 degrees Celsius in winterseason and 30 to 40 degrees Celsius insummer season.

The prime focus of this work is the problems of drainage channels in

Belgharia which an urban environmental setting.

1. Nature of drainage channels,

2. Problems of the drainage channels,

3. Compositions of materials blocking the drainage channels.

4. Techniques for managing the blocked drainage channels.

1.Nature of Drainage Channel:-

The geometry of the drainagechannel in the study area hasbeen observed to be of variousdimensions.

The dimensions of drainage channels in Belgharia

2. Compositions of materials blocking thedrainage channels :-Various materials are blocked the drainagechannels and result is water overflow in theroad. As is expected with the dimension of thedrainage channels in Belgharia,However, mostof the drainage channels have been blockedfollowing the anthropogenic activities in theBelgharia. Composition of material are nylon ,sand and stone , waste papers , tarpaulin ,plastics , tree roots and branch ,glass bottle andwaste materials

3.Problems of drainage channels :-

Many problems of diverse dimensionshave been observed in associationwith the incidence of drainageproblems in Belgharia and these areas follows.

4. Techniques for managing the blocked drainage channels :-

In spite of the seemingly intractable problems of drainage channelsand their effects in the urban area of Belgharia, a number of measureshave been suggested for minimizing the incidents of the problems ofdrainage systems as follows:

a. Drainage systems should be cleared with shovels on regular basis.

b. The need to avoid dropping waste materials into drainage channels.

c. The need to accentuate efforts on the construction of concretedrainage systems, which should be made very functional by ensuring,that waste are not dumped into them.

d. The need for environmental education with an emphasis on thetechniques for interacting with drainage systems .

Generally, for a very long period of time, Belgharia has beenwith serious drainage problems. However, once in a while, it isoften observed that blocked water drainage systems are beingcleared at irregular intervals. Indeed, such effort comes upwhen reports of drainage problems frequently comes up in theoffices of the authorities concerned. But, it is hoped that thiswork will stimulate a renewed interest in improvingenvironmental standard with a view to improving the well-being of man and his environmental setting
