Examples include modular seawalls that can be raised as needed; prefabricated highway bridges that can be elevated as peak flows beneath them rise; and floating intake systems at water treatment plants, designed to rise and fall as reservoir levels change.

Heightening river dykes reduces the probability of overflowing thus minimizing the floodplain storage and increasing the magnitude of peak flows downstream.

Olson says the increase in Mississippi River peak flow placed additional river pressure on levees and led to increased flooding, especially during the floods of 1927, 1937, 2011, and 2015 - 2016.

The identification of these controls on annual peak flows in the region may be of use in the context of seasonal prediction or future projected streamflow behaviour.

The effect is greatest at lower elevations (where snowfall is more marginal)(Jasper et al., 2004; Knowles and Cayan, 2004), and in many cases peak flow would occur at least a month earlier.

Glacier Peak flow occurs when non glacier flow is approaching minimum values.

More specifically, rooflite soil systems do a few different things to manage stormwater: retain water in the soil for the plants, return water to the atmosphere through evapo - transpiration, dramatically reduce peak flows, and significantly delay any remaining run - off.

And some of Europe's rivers could experience peak flows 80 % higher than any today, which means ever - greater flood hazards, in particular for north - west European cities.

A peak flow meter is a small device that your child blows into and, based on the number they blow, can help parents gauge if the child is having asthma trouble or is in good control.

Peak flows can help you monitor your child's asthma once they are five to six years old.

Since some baby boomers have a diminished awareness of how well or poorly they are breathing, and seem to have a harder time overcoming their perception of breathlessness, self - monitoring with a peak flow meter is strongly recommended during an asthma attack.

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.

However, it also had the unintended consequence of increasing the peak flow of Mississippi River water south of Cape Girardeau through the Thebes gap and south to Helena, Arkansas, a distance of approximately 360 river miles.

Large changes and trends in seasonal streamflow rates for many of the world's major rivers (Lammers et al., 2001; Cowell and Stoudt, 2002; Ye et al., 2003; Yang et al., 2004) should be interpreted with caution, since many of these streams have been affected by the construction of large dams and reservoirs that increase low flow and reduce peak flow.

He encourages his patients to use a peak flow meter to monitor their lung function on these sweltering days.

Half of the year, the Macal can be paddled upstream, except during the peak flow months of June to October.

Measures include the rise of flood protections, reduction of the peak flows through water retention, reduction of vulnerability and relocation to safer areas.

Even the smallest, were it to drain completely, would tip a peak flow of 600 cubic metres of water a second down the hillside.

After a flood had hit, a recurrent case of flood management was to reinforce and rise flood protections up to a level that would safely confine the peak flow of the river in case a similar event occurred again in the future (see e.g., Fenn et al. 2014).

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).

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.

The benefits of methods relying on reducing the exceedance of flood thresholds (i.e., rising flood protections, reducing peak flow) heavily depend on the future climate scenario.

In real world applications, peak flow reduction rates rarely exceed 50 % (Pasche et al. 2008; Reinhardt et al. 2011) and tend to decrease with the event magnitude and with the catchment area.
