Abstract:
The present study aims at the investigation of the
1ysico—chemical features of a tropical tidal river viz.
we Muvattupuzha river. This river is expected to receive
Jderate to heavy pollution loads in years to come, from
we lone industrial unit, already set up on its bank.
ilike other rivers, the geographical disposition of this
Lver attains unique importance as regards its dynamics for
3) availability of natural runoff water from catchment
:eas, which becomes very heavy during the monsoon season
3) regular steady availability of tail race water from a
/dro—electric power station throughout the yearThe study also aims at arriving at the balancing
forces of inherent self~purification of the river verses
pollution loads from the factory effluents. The investigation
period falls ahead of actual pollution occurrence
and so the ambient conditions for a period of nearly
one-and-a—half years were investigated, the analyses of which
providflz to formulate the inter-relations of parameters
varying with seasons. Tracer experiments were carried out
which revealed the dispersion and dilution characteristics
of the river in the vicinity of effluent outfall. The
studv covers the trial—cum-capacity production periods
of the factory during which effluents of various strength
and quantity were discharged into the river; a few computed
values arQ’cjmpgrQdl ... with the observed values. The
base data along with the profiles of Oxygen sag equation have
been utilized fb develop a mathematical model of the
river with regard to its water quality
