Getting better at predicting this kind of extreme rainfall would
help water managers plan for the future.
In consultation
with water managers, research organisations and government agencies, priority research themes and four research sites have been identified.
As climate change and population place further pressure on tight water resources, the researchers found that policymakers and
water managers need to take a regional and global perspective on local decisions.
We work to ensure that green infrastructure becomes the preferred mechanism by which
water managers meet a range of water management goals for people and wildlife under changing climate conditions.
Considering that the drought is ongoing in many of the districts,
water managers fear the findings for 2012 and perhaps even 2013 will be similarly severe.
By then, she'll have an even better idea of the extent of the problem to present to
state water managers.
It is critical to understand what is causing it
so water managers can make realistic water use and conservation plans.
Their findings, which also aim to shift how flood risks are communicated, could have fundamental implications
for water managers, agricultural interests and the people who live in flood - prone regions.
Climate change is likely to influence rainfall patterns in the Sierra Nevada as well as the amount of dust that makes its way into the atmosphere, so the hope is that a better understanding of how aerosols affect precipitation will help
water managers in the future.
Andy, I've been engaged in understanding this drought event, having just returned from Sacramento where I briefed a group
of water managers and emergency responders on the drought.
Urban water managers in Australia have been forced to put in place aggressive strategies to curb water use and to expand sources of new and unconventional supplies.
«We identify long - term and annual priorities to help environmental
water managers target water to where it will have the best impact,» Mr Binning said.
That is still well below the long term mean of just above 7 maf for April through July, but given the slim margins
facing water managers right now the bonus water provides a crucial boost.
Precipitation declines combined with booming urban populations will present a significant challenge to
Western water managers in the near future.
Report of the Expert Meeting
on Water Manager Needs for Climate Information in Water Resources Planning (Geneva, Switzerland, 18 - 20 December 2006)
Hot weather and low snowpack are a historically bad combination that worries
water managers across the West.
As farmers in the American West decide what, when and where to plant, and urban
water managers plan for water needs in the next year, they want to know how much water their community will get from melting snow in the mountains.
South Florida
water managers use a variety of techniques to help control the plant after people toss it into canals, she said, but none of them does a good job of killing the plants.
«There will be a series of recommendations that will be coming out this summer to try and help
water managers better understand how to do this.»
And whereas standard solutions might have been good enough when there were fewer pressures on water quality and demand on water as a shared community resource,
today water managers have to design to a much tighter and demanding sustainability brief,» he says.
«
As water managers, we need to be prepared to actively manage our water holdings to get the best outcome from every drop - whether that is through using the water for environmental flows or by trading it.»
Since water managers are largely following the West's rigid planning model, these countries are going to have difficulty adapting to changes in water availability.
New Delhi's endemic shortfalls occur largely
because water managers decided some years back to divert large amounts from upstream rivers and reservoirs to irrigate crops.
Previously,
many water managers in the region had believed that the algae blooms of the diatom Didymosphenia geminata — which resemble blobs of wet toilet paper or shag rugs — resulted from an invasive species problem starting in the mid-2000s that could be fixed by regular washing of fishing gear and other sanitation measures.
The project studies water resources in the Phoenix area with the goal of understanding decisions about scarce water resources and their impacts: How do
water managers think about climate uncertainty?
The two researchers wanted to
provide water managers with insight into how future projections of temperature and precipitation for the Colorado River Basin would affect the river's flows.
Melissa Haeffner, a PSU environmental science professor and the study's principal investigator, said that residents who received communications from their local water bureaus or served on a city water system advisory board or committee had perspectives and concerns that were more aligned with those of political leaders and
professional water managers.
Drought conditions during most of the 21st century have
forced water managers to plan for a day when the region's vast system of dams and reservoirs no longer have enough water to store.
Increasing water
supply Water managers are looking to replace the projected losses of snowpacks, which serve as natural reservoirs, with new and expanded ways of storing water.
In states like California, which is currently in the midst of a crippling drought, the
more water managers know about how much snow is in the mountains, the better they can plan for the summer to come (Greenwire).
«The idea is to make it available in near real time and be able to give it to
[water managers] one, two, five days after,» said Argus.
She adds that the study «proves twice over» how much of the change is due to climate change versus human consumption — vitally important for helping
water managers predict water needs.
The answer couldn't be more important for
regional water managers — planning for a «return to normal conditions as the cycles progress» could be the most disastrous plan ever — but if you read the press, you won't find any coverage of it.
The Northwest Climate Toolbox is a suite of free online applications designed by CIRC researchers and intended to help foresters, farmers, and
water managers respond to and prepare for climate variability and change.
That in turn could be achieved by adjusting the way they apply water to the fields, the kind of crops they grow and the way that state and
federal water managers deliver the water.
In the face of more extreme climate change - induced droughts,
water managers often underestimate worst - case scenario low flows because the most extreme naturally occurring events are rarely captured within short instrumental records.
In my own work, I have observed urban
water managers around the country experimenting with incentives to promote water - conscious landscaping alternatives, rebates for lower water use appliances, better leak detection systems, and re-use systems.
