Sentences with phrase «m3 of runoff»

In August 1985, Lewis Glacier had an area of 0.09 km2 and released 0.15 x 106 m3 of runoff.

Glaciers alone provide 750 million m3 of runoff each summer (Fountain and Tangborn, 1985).

In fact in a dry year such as 1998 glaciers yielded 110 million m3 of runoff to Baker Lake, while other sources were below average, which amounted to 45 % of the total basin flow (Pelto, 2008).

Not exact matches

By August 1990, Lewis Glacier had disappeared, runoff from the former glacier basin was 0.04 x 106 m3, only 27 % of the glaciated flow, despite the presence of some relict glacier ice, and that total monthly precipitation was the same.

Mechanical thinning of ponderosa pine forests in the first analysis area of the 4FRI project — 6,190 ha / year for ten years totaling 61,900 ha (15,300 ac / year; 153,000 acres total)-- increased mean annual runoff from 3.13 million m3 (2,540 acre - feet) in a simulated drought to 7.27 million m3 (5,890 acre - feet) in a pluvial.

Depending on winter precipitation and the forest treatment schedule, mean annual increases in runoff from thinning of ponderosa forests across the Salt - Verde watersheds ranged from 4.76 to 15.0 million m3 (3,860 — 12,200 acre - feet) over a 35 - year treatment period, 6.18 to 23.4 million m3 (5,010 to 19,000 acre - feet) over 25 years, and 9.23 to 42.8 million m3 (7,480 to 34,700 acre - feet) over 15 years (Table 2).

Using a simulation model, Brown and Fogel [40] found that thinning approximately 9,300 ha (23,000 acres) of ponderosa pine per year over a 10 - year period produced increases in runoff that ranged from 0.28 to 11.8 million m3 / year (230 — 9,600 acre - feet / year).

Effects of increasing (a) pace and (b) extent of thinning treatments in ponderosa pine forests in Salt - Verde watersheds on increases in mean annual runoff (million m3 / year).
