Hydrology Quotes (9 quotes)

All rivers, small or large, agree in one character; they like to lean a little on one side; they cannot bear to have their channels deepest in the middle, but will always, if they can, have one bank to sun themselves upon, and another to get cool under.
In 'Water', The True and the Beautiful in Nature, Art, Morals, and Religion (1872), 62.

I chatter over stony ways,
In little sharps and trebles,
I bubble into eddying bays,
I babble on the pebbles.…
And out again I curve and flow
To join the brimming river;
For men may come and men may go,
But I go on forever.
From 'Song of the Brook' (1842), collected in The Poetical Works of Alfred Tennyson (1873), 142.

My sense is that the most under-appreciated–and perhaps most under-researched–linkages between forests and food security are the roles that forest-based ecosystem services play in underpinning sustainable agricultural production. Forests regulate hydrological services including the quantity, quality, and timing of water available for irrigation. Forest-based bats and bees pollinate crops. Forests mitigate impacts of climate change and extreme weather events at the landscape scale.

Trees are great promoters of lakes and rivers…; for, since the woods and forests have been grubbed and cleared, all bodies of water are much diminished; so that some streams, that were very considerable a century ago, will not now drive a common mill.
Letter (7 Feb 1776) to Daines Barrington, collected in The Natural History of Selborne (1813), Vol. 1, 348.

Trees perspire profusely, condense largely, and check evaporation so much that woods are always moist: no wonder, therefore, that they contribute much to pools and streams.
Letter (7 Feb 1776) to Daines Barrington, collected in The Natural History of Selborne (1813), Vol. 1, 348.

We stand by the river and admire the great body of water flowing so sweetly on; could you trace it back to its source, you might find a mere rivulet, but meandering on, joined by other streams and by secret springs, and fed by the rains and dews of heaven, it gathers volume and force, makes its way through the gorges of the mountains, plows, widens and deepens its channel through the provinces, and attains its present majesty.
From Address (1 Aug 1875), 'The Growth of Principles' at Saratoga. Collected in William L. Snyder (ed.), Great Speeches by Great Lawyers: A Collection of Arguments and Speeches (1901), 246.

Where there are reeds, there is water.
In John Ray and Henry George Bohn (ed.), A Hand-book of Proverbs: Comprising an Entire Republication of Ray's Collection of English Proverbs (1860), 564.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
