Loss of Alkaline Earth Elements by Runoff from Agricultural Watersheds

Scale invariance of daily runoff time series in agricultural watersheds

Fractal scaling behavior of long-term records of daily runoff time series in 31 sub-watersheds covering a wide range of size were examined using the shifted box-counting method and Hurst rescaled range (R/S) analysis. These subwatersheds were associated with four agricultural watersheds of different climate and topography. The results showed that the records of daily runoff rate exhibited scale...

Statistical estimation of runoff characteristics of watersheds in central Chile

Estimation of monthly runoff statistical properties, such as monthly means and variances, is usually needed to design and evaluate water resource systems. If no local recorded data are available, a transfer of information through different alternative procedures can be used. In this paper, the use of linear Transfer Function (TF) models with precipitation series as inputs is proposed to estimat...

Offshore and nearshore chlorophyll increases induced by typhoon winds and subsequent terrestrial rainwater runoff

The response of phytoplankton chlorophyll to Typhoon Damrey in the South China Sea (SCS) in September 2005 was studied by remote sensing. Chl a concentration increased in 2 areas after the typhoon: (1) An offshore bloom along Damrey’s track exhibited a chl a peak (4 mg m–3) 5 d after the typhoon’s passage. It was preceded by sea-surface cooling (–5°C), mainly on the right side of the typhoon tr...
