The rivers flow across the plain in broad, level valleys, only a few hundred or even only a few dozen feet lower than the watersheds; they separate into many branches, enclosing islands, forming creeks, and drowning wide tracts of land during inundations.
The loess covers both the watersheds and the valleys.
This chain may be regarded as a single geographical feature, forming one of the principal watersheds of the peninsula, the waters to the north draining chiefly into the Nerbudda and the Ganges, those to the south into the Tapti, the Mahanadi, the Godavari and some smaller streams. In a meteorolgical point of view it is of considerable importance.
They are provided with well-proportioned watersheds and rainfall, and being nearly all more than 500 ft.
In the neighbourhood of the Sahyadri hills, particularly towards the northern extremity of the range, the country is rugged and broken, containing isolated peaks, masses of rock and spurs, which, running eastward, form watersheds for the great rivers of the Deccan.
