The application was envisaged for providing irrigation to Kanjikode -
Kozhijampara area. The project was conceived 2 decades ago but did not
materialize due to objection from forest department. Scenarios were run for
different levels of submergence using DEM. Mike Basin was used to analyze the
amount water conveyed through tunnel and the hydropower generated.
The unutilized capacity of Parambikulam reservoir is made use of for
supplying water to Palakkad region in the summer months.
The process of supplying the water to Contour canal in the monsoon
months and receiving back a lesser amount in summer months is
equivalent of having a new reservoir of capacity 90Mm3 up in the
Western Ghats without any cost. (Capacity of the proposed Karapara
reservoir is only 28Mm3.)
The most suitable option appears to be the 2nd scenario in which
maximum water (164.3Mm3) is transferred to Contour canal from
Karapara and Upper Kuriarkuty and getting back a stable flow of
88.6Mm3 in summer months for power and Irrigation.
The water availability at Moolathara will be doubled from 7.5 TMC (as per
PAP agreement), if the project is implemented.
Forest submergence will be minimum in this proposal.
The power generated will be around 15 MW from Karapara and 30MW from
Main tunnel. Power can be produced in the summer also.
The power generated from the project will be more than 200MW if only peak
hour generation is followed.
During heavy rainy season, the main tunnel can also be used for transferring
flood water from Chalakudy basin to Bharathapuzha basin, where flood does
not cause much damage.
Artificial Recharge Viability Analysis
A project proposal amounting to 7.5 crores was submitted before the Kerala State Ground Water
Authority which in turn has recommended to the Government for the final nod.
Inter Sub Basin Transfer
This application was to study the viability of inter sub basin water transfer during
monsoon season to rain shadow regions and there by to augment the ground
resource of the area.
Water Availability of Bharathapuzha Basin

Simulated data of seven reservoirs in the Study Basin was integrated using DSS
(P) Software. Inflow (including dependability), Water level, Demands etc. can be
viewed and exported to MS Excel. This will help Officers involved in Water
Resources planning to take decisions on Water allocation.

mentioned earlier was carried out on such directions.
Detailed documentation on all the developed
applications is in progress.

also focuses on the extension on HP…
1. License issue for model tools
Now no network License for modelling………
2. TOT Training and Training in MIKE HYDRO
No body is trained in MIKE HYDRO (New Modelling Software). In House training
programme is needed for DSS team Members and other officials.
TOT Programme originally planned for the state was not materialized.
3. Less training in DSS(P) Software
An exhaustive training was lacking.

Findings of the Study
The major water quality problem associated
with rivers of Kerala is bacteriological pollution.
The study also revealed that industrial pollution of
surface water is not much in Kerala compared to
other States of India.
In some of the rivers viz Periyar, Muvattupuzha etc
which directly receive untreated industrial effluents,
the pollution is in an alarming rate.
Salinity is another problem observed in the coastal
In general the water quality deterioration is
reported to be mainly due to anthropogenic
Large scale urbanization, indiscriminate disposal
of solid and liquid waste, changes in land-use
and agricultural practices contribute
significantly to the water quality deterioration
Bacteriological contamination is mainly due to
poor sanitation practices
There is an urgent need to make integrated efforts by
different Government as well as Non-Governmental
organizations in order to address issues related to large
scale contamination of fresh water resources to provide the
desired quality of water to various stake holders in Kerala.
A regular water quality monitoring program covering the
Adequate and well trained technical staff is required for
carrying out the analysis utilizing advanced equipments in
the WQ laboratories.
Appropriate Scientific interventions and management practices
are required to be evolved for proper disposal of solid and
liquid waste as these lead to the contamination of the available
fresh surface as well as ground water resources.
Scientific, cost-effective and environmental friendly Mitigation
activities are to be practised.
Establishing Web based water quality information System.
Mass awareness programs to manage water quality and related
Water Quality related studies to be continued with extended
objectives and scope to address the water quality problems of
Kerala State in a Holistic Manner.
