General description

Overview of Challenge

5

What is the nature of the challenge? (What is not adequately addressed at present?)

Engineering or survey crews can be caught out in large river basins when flash floods occur upstream.  They receive no warning and only know about it when the water is actually on them.

6

Thematic information requirements

3. Obtain detailed vegetation information,  4. Obtain detailed land-use information,   6. Identify inland water bodies and determine water quality,    9. Obtain detailed imagery of assets,

7

Nature of the challenge - What effect does this challenge have on operations?

If they were given better notice they could ensure that equipment and personnel are clear of the danger area.  This would improve H&S and reduce damage to equipment.

8

What do you currently do to address this challenge?/ How is this challenge conventionally addressed?

Local knowledge is used where possible, together with met forecasts.

9

What kind of solution do you envisage could address this challenge?

Very high to medium resolution EO data can provide timely images of the changing flood waters.

 

10

What is your view on the capability of technology to meet this need? – are you currently using EO tech? If not, why not?

EO could be a useful complimentary technology
