The strategy is simple: Maybe a challenger could win in the primary, but the chances could be better in a runoff
where only the most active voters turn out.
Interestingly, insurance runoff
isn't that much different.
The concentration of phosphorus (P) in runoff
from agricultural land is assumed to have two components, an 'incidental' loss that relates to management, such as the application of manure and fertiliser, and a 'systematic' loss that relates primarily to the concentration of soil P and P-buffering capacity (Hart et al.
But Moore has conducted a number of studies over the past 10 years showing that drainage ditches where plants are allowed to flourish are strikingly effective at keeping agricultural pollutants in field runoff
from reaching surrounding surface waters.
Phosphorus (P) contained in runoff
from agricultural land contributes to a decline in surface water quality.
This model is a distributed, cell-by-cell, event-based watershed model that predicts surface runoff
(including total runoff
volume and peak runoff
rate), sediment yield, and nutrient loading of phosphorus, nitrogen, and chemical oxygen demand (COD) on the basis of 22 input parameters derived from soil, land cover, and elevation data (Young et al.
Under pressure to take steps to clean urban runoff
and improve water quality, the Los Angeles City Council on Wednesday approved spending more than $230 million on projects ranging from cleaning up lakes to dealing with storm-drain runoff
2 percent made the runoff
, defeating Mike Schofield with 19.
agreed to settle three lawsuits that address stormwater runoff
into Potash Brook--a tributary of Lake Champlain.
from roads and storm drains--non-point source pollution--is also a significant issue.
Hydrologic changes including increased impervious area, soil compaction, and increased drainage efficiency generally lead to increased direct runoff
, decreased groundwater recharge, and increased flooding, among other problems (Booth 1991).
To gauge the relative importance of the transpiration change to global freshwater flow, Stott and his colleagues compared actual river-runoff
data from the past century with runoff
calculated in models that take account of climate change, solar radiation, deforestation, and carbon dioxide--driven changes in transpiration.
