And our soil does a few different things — retains water in the soil for the plants, returns water to the atmosphere through evapo - transpiration, dramatically
reduces peak flows, and significantly delays any remaining run - off.
Further adaptation measures to
reduce the peak flow should make use of natural retention capacity upstream, while rising flood protections should be seen as last resort, to compensate for the residual risk in areas where other options can not be implemented.
Not exact matches
Actions to
reduce stormwater runoff in ways that allow water to infiltrate and move more slowly through the ground can also ease flooding and
peak flows that otherwise threaten salmon redds.
«Many wetlands soak up runoff and floodwaters, which
reduces peak flood -
flows and avoids costly flood damage.»
A
reduced snow cover extent in the mountainous West changes the
peak river
flow, as does timing of increases in heavy and extreme precipitation reported in the United States, which is best reflected during the warm season.
Since the congestion charge was adopted, the daily
flow of cars and minicabs into central London during
peak hours has been
reduced by 70,000, a drop of 36 percent, while the number of bicycles has increased by 50 percent.
In addition,
peak flows are
reduced by reservoirs, sustainable urban drainage systems (SUDS, e.g., Pasche et al. 2008), retarding basins, infiltration basins, and through targeted land management plans such as afforestation and river renaturation (Reinhardt et al. 2011).
Heightening river dykes
reduces the probability of overflowing thus minimizing the floodplain storage and increasing the magnitude of
peak flows downstream.
But
peak water
flow is typically a seasonal event driven by snowpack melt, so the price -
reducing effect of hydropower normally lasts only a few months each year, typically in the spring and early summer.
Streamlined operations and work
flow, resulting in
reduced response times as well as greater efficiencies during increased
peak workloads.
