ENVIRONMENTAGENCY Conveyance Estimation System
• Practitioners using the CES results - training to understand results and their inherent uncertainties
• Modellers - training, support and licences
• Academics - training, support, source code, upgrade
• Software Developer - source code, uptake
• Funders - uptake, upgrade
Stakeholder needs

ENVIRONMENTAGENCY Conveyance Estimation System
Product Analysis• Stand-alone CES
- Roughness advisor- Conveyance generator- Uncertainty estimator- Backwater calculation
• CES implemented as a 1-D modelling package in iSIS (or other commercial models)
• CES implemented in bespoke modelling systems
• Supplying Conveyance Estimator algorithms on Open-source basis

The Impact of the CES• A new culture is emerging on best practice in
conveyance estimation
• Relevant to this culture are: software licences, training, support, upgrading the software, sharing experience, improving practice
• The new culture reinforces “preventing the reinvention of the wheel” - open Source
• I flag the need for a policy to cover these issues

CES and similar Initiatives• MDSF, RASP, PAMS, AES
• EPSRC Consortium on Flood Risk Management
• One common thread is opening up source codes
• Not to forget HarmonIT and NFFS, ARION
• All of these put an emphasis on opening up
![Page 9: The Presentation on the Roll Out of the Conveyance Estimation Method](https://reader031.fdocuments.us/reader031/viewer/2022030401/58ae492d1a28abad338b6251/html5/thumbnails/9.jpg)
ENVIRONMENTAGENCY Conveyance Estimation System
Open Source - 1
• ‘Open source’ is defined as the software source
code freely shared and improved
• Only viable through institutional Arrangement
referred to as Free Software Foundations - the
analogy of peer-reviewed journal papers
![Page 10: The Presentation on the Roll Out of the Conveyance Estimation Method](https://reader031.fdocuments.us/reader031/viewer/2022030401/58ae492d1a28abad338b6251/html5/thumbnails/10.jpg)
ENVIRONMENTAGENCY Conveyance Estimation System
Open Source - 2• It encourages widespread interoperability
and rapid development
• It gives a new meaning to competitions by preventing the reinvention of the wheel - no more cold starts
• Interconnectivity among software modules
• Who pays? a viable enterprise for upgrading
• It is not the full solution
![Page 11: The Presentation on the Roll Out of the Conveyance Estimation Method](https://reader031.fdocuments.us/reader031/viewer/2022030401/58ae492d1a28abad338b6251/html5/thumbnails/11.jpg)
ENVIRONMENTAGENCY Conveyance Estimation System
Towards PolicymakingWe looked at:
• Diversified new applications: CES/AES, RASP, PAMS
• Interconnectivity of these new applications
• Diversified stakeholders
• Lifecycle management with a focus on upgrade
• Gaps and the need to forming FSF
• So a policy is needed to bring these under its umbrella

Strategy
• Everyone should play their role
• The Agency is formulating its modelling strategy for flood risk management
• The Whole System Modelling Theme of the EPSRC Consortium on FRM can take up the issue of Free Software Foundation
![Page 13: The Presentation on the Roll Out of the Conveyance Estimation Method](https://reader031.fdocuments.us/reader031/viewer/2022030401/58ae492d1a28abad338b6251/html5/thumbnails/13.jpg)
ENVIRONMENTAGENCY Conveyance Estimation System
Conclusion• The CES is moving from proof-of-concept to rollout
• Elements have emerged to form policies/strategies at the rollout stage
• Working in partnership in an evolving background
• A repertoire of open-source based software products have emerged flagging the need for FS Foundations
• FSF solves the problem of public organisations in contributing towards towards developing best practice
