Climate scientists predict that many parts of the world will be increasingly prone to floods.
气候科学家预测,世界许多地区将越来越容易发生洪水。
This is a serious risk to human lives and property.
这是对人的生命和财产的严重威胁。
So understanding and accurately forecasting flood risks is a key challenge for vulnerable cities around the globe.
因此,了解和准确预测洪水风险是全球各地脆弱城市面临的一个关键挑战。
In 2017, Derek Loftis of the Virginia Institute of Marine Science started a project called Catch the King.
2017年,弗吉尼亚海洋科学研究所的德里克·洛夫蒂斯(Derek Loftis)启动了一个名为“抓住国王”的项目。
It uses a smartphone app to collect the data of ordinary citizens during high tides.
它使用智能手机应用程序在涨潮时收集普通市民的数据。
He'll use those data to validate and improve his mathematical flooding model, called TideWatch.
他将使用这些数据来验证和改进他的数学洪水模型,称为潮汐观察。
Loftis's mission is to know where the water goes before it goes there.
Loftis的任务是在水流到哪里之前就知道它去了哪里。
But collecting necessary data and then processing that information quickly enough to make usable forecasts is anything but easy.
但是,收集必要的数据,然后足够快地处理这些信息以做出可用的预测绝非易事。
Accurate flood forecasts require an understanding of the situation on the ground.
准确的洪水预报需要对实地情况的了解。
By the early 2000s, supercomputing had advanced enough that scientists could integrate weather forecasting models with such measurements.
到21世纪初,超级计算已经有了足够的进步,科学家可以将天气预报模型与这样的测量结合起来。
But they still didn't have the critically important ability to forecast fast-moving floods in real time.
但是他们仍然不具备实时预报快速移动的洪水的重要能力。
So, in 2017, Loftis and colleagues set up a group of 28 Intemet-connected water-level sensors throughout the flood risk community of Norfolk, Virginia.
因此,2017年,Loftis和同事在弗吉尼亚州诺福克的洪水风险社区建立了一组28个与互联网连接的水位传感器。
The new sensors relayed rough measurements about water height and movement to a computer at the Virginia Institute.
新的传感器将水的高度和运动的粗略测量值传送到弗吉尼亚研究所的计算机上。
Along with those sensors, hundreds of local citizens take photos of rising tides and transmit them in real time to the institute.
与这些传感器一起,数百名当地居民拍摄涨潮的照片,并将其实时传输到研究所。
Scientists hope that the data collected by these citizens can help sharpen the ability to forecast exactly when and where damaging floods will occur.
科学家希望这些公民收集的数据可以帮助提高准确预测破坏性洪水将在何时何地发生的能力。
