Abstract:
Water scarcity is an alarming problem that we face now-a-days. Even though we
have abundant sources of water, good quality water is not available when needed. Here
comes the relevance of water conservation structures. Allocation of water in case of multi-
purpose projects among various competing needs such as drinking water, irrigation, industrial
demands, downstream release etc. is a matter of great concern. Hence reservoirs must be
subjected to thorough analysis to see that each drop of water impounded is utilized in the best
possible manner. So a study was undertaken for analyzing the impact of Regulator cum
Bridges at Chamravattom and Kootayi in Malappuram. The study conducted at
Chamravattom with the specific objectives of determining the impacts of RCB on water
quality, soil characteristics, ground water recharge, agriculture sector, tourism possibilities,
transportation and ecosystem. And the study conducted at Kootayi with the specific objective
of determining the impact of RCB on water quality.
Chamravattom regulator cum Bridge have number of positive impacts in terms of
prevention of saline intrusion, increase in ground water table, improved irrigation facilities,
increase in area of production, better socio-economic status, improved transportation and
communication facilities and also promising future in tourism. Chamravattom Bridge has
provided some disadvantage along with advantage. The main disadvantage comes under the
narrow roads on this route. The benefit of reduction of duration actually gets to people only
after the development of the route. And also water near to Chamravattom Bridge has a foul
smell after closing the shutters, which is also reported in the case of Kootayi RCB. The
results of the present study reveals that a thorough EIA of the RCB‟ s are to be conducted to
assess the negative impacts on the upstream side and appropriate corrective / remedial
measures are to be taken to over cum the negative impacts. Finally, there is a need for
increased education and awareness programs to improve the conservation needs and profile
of the Bharathapuzha River system.
