The
Western Ghats provides a principal geographical barrier in the path of the
Arabian Sea branch of the Southwest monsoon, and is principally responsible for
the heavy rainfall over the western coastal belt. The Southwest monsoon season
(june to september) is the principal rainy season, over 90 % of annual rainfall
is realised in this period.
The
rivers in the Western Ghats region generally originate at an elevation ranging
from 400 meters to 1,600 meters above the mean sea level, close to the Western
Ghats ridge. The rivers generally flow westward and meet the Arabian Sea after
a short run varying from 50 kms to 300 kms. the
rivers are very steep in the upper reaches and fairly steep in the middle
reaches. It is only near the sea that they have relatively flat gradients and
some sort of flood plain.
The
list of west flowing rivers, their important tributaries and the states through
which these are flowing are given in the following table. There are a number of
free catchments, between the identified river basins, which have small streams
directly draining into the Arabian Sea. These free catchments are close to the
sea and are at lower elevation.
