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.
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.
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.
M., and includes the greater part of the vast plateau of Old Castile, between the watersheds of the Cantabrian Mountains, on the north, and the Guadarrama, Gredos, Gata and Estrella ranges, on the south.
The loess covers both the watersheds and the valleys.
45 0; then an irregular line partly determined by watersheds and rivers divides Canada from Maine, coming out on the Bay of Fundy.
Broad, in which the chief watersheds are those of the Garonne, Dordogne, and their confluent the Gironde.
Watersheds are rarely used as boundaries for any distance; but, although slightly overlapping the watershed on all sides, Yorkshire is very nearly coincident with the basin of the Ouse.
The boundaries of the parishes, the fundamental units of English political geography, are very often either rivers or watersheds, and they frequently show a close relation to the strike of the geological strata.
They are provided with well-proportioned watersheds and rainfall, and being nearly all more than 500 ft.
Its rivers flow easterly into the Atlantic and drain a triangular-shaped area of the plateau lying between the northern frontier and the southern and western watersheds of the Araguary, whose extreme limits are about o° 30' N.
Where the Nile, Congo and Shari watersheds meet.
By its vicinity to the watersheds of the Eurotas and Alpheus, and its command over the main roads from Laconia to Argos and the Isthmus, Tegea likewise was brought into conflict with Sparta.
The great central area of Canada is drained towards Hudson Bay, but its two largest rivers have separate watersheds, the Mackenzie flowing north-west to the Arctic Ocean and the St Lawrence north-east towards the Atlantic, the one to the south-west and the other to the south-east of the Archean protaxis.
Thus the figure and area of a surface watershed may not be coincident with that of the corresponding underground watershed; and the flow in any watercourse, especially from a small watershed, may, by reason of underground flow from or into other watersheds, be disproportionate to the area apparently drained by that watercourse.
The surface is undulatory; marshy meadow lands no longer exist on the flat watersheds, and only a few in the deeper and broader river valleys.
