Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia.
Even in the remote and seemingly pristine landscape of Alaska's Brooks Range, the rivers are poisoned by mercury, a toxic metal.
Entering a 40-mile (65-km) gorge between the Krichauff and James ranges, the river emerges upon mudflats and sand flats to be joined by the Palmer and Hugh rivers.
It derives its name from a Maori term meaning "place for dancing". Rising on the Kaweka and Ahimanawa ranges, the river flows southeast, northeast, and southeast once again, entering Hawke Bay of the Pacific Ocean.
Recent archaeological work, driven by 2018 data analytics, has unearthed evidence of the Rappahannock Tribe's vast range along the river that bears its name.
The mountains, the ranges, the rivers and lakes, the snow, the dirt, and the green, then gold, then red leafed vines.
Variograms of both horizontal and vertical K show a clear directional anisotropy with ranges along the river being twice as large as those across the river.
The difference in the pH range of the rivers is primarily a result of the local geology [ 14, 25], so river pH is unlikely to have changed within the timeframe (Mio-Pliocene) required to result in the isolation of lineages.
Their natural range would be the river bottoms and sage flats.
This parameter ranges over the rivers studied between 0.18 and 1.22, allowing classification of rivers as having very low (< 0.20), low (0.20 0.40), moderate (0.40 0.60), high (0.60 0.90), or very high (> 0.90) annual peak discharge variance.
However, the increase in the irregularity of flow regimes and the decrease in water ranges of the rivers due to global warming in recent years have revealed that supporter systems are necessary.
