Responses to selected questions that we did not have time to address during the live Q&A session are listed here.
The recent, devastating floods in eastern Australia have created a substantial, immediate need for engineers with water skills. Find out how to get involved here:
While this webinar focussed on WASH projects, many of our webinar attendees have a flood modelling background and have expressed a desire to help.
Flood modelling can only be accurate as the underlying LiDAR or survey details. In many low-income countries, no level of surface water modelling skills will be able to produce valid data, because there is insufficient terrain and bathymetric data available, limiting confidence in the results of any analysis. Also, in many cases, topographic data that has been acquired is held privately and not available for public use without substantial payments.
In many cases, the best return on investment for flood modelling would involve the capture or provision of accurate terrain data. Visit https://dronesforearth.org/ and the UNICEF supported African Drone and Data Academy to get involved in providing drone technology to areas in need.
HOW CAN SURFACE WATER SOLUTIONS HELP?
For our part, we are offering free hydraulic modelling advisory services for low income countries. If you are a water modeller or practicing/retired water engineer with flood modelling skills and would like to get involved in a supporting advisory or mentoring role, please send an e-mail to aid@surfacewater.biz.
We currently have more requests for support than we can accommodate, so we have to be selective in the projects we assist with. To help meet the demand, we welcome input from those with the means and skills to contribute. We’ll provide respondents with access to the projects for which assistance is needed.
[NOTE: Advice offered through this programme is strictly limited to software, analysis approach, methodologies, principles, background theory, and related conceptual material. Any advice involving project implementation, such as levee heights, spillway capacity, dam design, and related engineering guidance can only be provided with appropriate contractual and insurance details in place under agreed terms and conditions.]
