(iii) Develop a modern and adaptive national WRIS adhering to international best practices. (vi) Support MOWRAM to establish sustainable O&M systems for the NWRDMC and WRIS Specifically, the Objectives of the contract include: (i) Conduct of a rapid assessment of the status of WRIS and NWRDMC development, clarify and confirm the WRIS and associated systems development strategy and establish clear deliverables that ensure no duplication of past or ongoing effort, (ii) Review and the water resources information needs of government agencies to inform the ongoing design of a modern NWRDMC and WRIS, (iii) Confirm outstanding design requirements of the WRIS and other data systems to be operated by the NWRDMC based on the review of work completed under IAIP to date, government consultations, and input to reflect international best practice. The scope of design will be formally agreed by MOWRAM and reviewed by ADB with a formal concurrence prior to work proceeding. (iv) Provides support to MOWRAM PMIC procurement and contract management specialists, support MOWRAM in the procurement of Goods packages related to the WRIS and NWRDMC information services (v) Support equipment suppliers in the installation of equipment, hydrometeorological instruments, accessories and related cabling within the spaces allocated to the WRIS on the first floor of the NWRDMC and at field monitoring sites. (vi) Develop a modern and adaptive national WRIS operated on the Delft-FEWS platform and incorporate the IAMS and FAO’s WAPOR software to the best international practice standard and transfer this to MOWRAM staff. (viii Develop to full operationalization and institutionalization of the water resource information system (WRIS) that is maintained and informs on IWRM for future sector investments, including increased climate change resilience to mitigate damages and losses from floods and drought to the economy, (ix) The consultant will prepare a detailed work plan and budget for the development of river modelling within economic pole 4 for identification of sector investments using the capability of the WRIS and NWRMDC (x) Develop and implement a capacity building program for the MOWRAM staff assigned to operate and maintain the WRIS and NWRMC including client interfaces and responses to requests for the provision of water resources information or modelling outcomes. (xi) Support MOWRAM to strengthen the hydrometeorology network and data interpretation for weather systems and early warning including the installation of procured instruments at identified monitoring sites, support to data recording and archive into the NWRDMC databases. (xii) Assist in connecting the Dopler radar building established under the existing IAIP project into the NWRDMC databases and decision support to improve early warning for rainfall events – including automatic data sharing with the Civil Aviation sector. (xiii) Support MOWRAM to establish and implement O&M systems for the WRIS and a wider data support system within NWRDMC including both hardware, software, databases and server records. (xiv) As part of the transfer of systems and building of the institutional role of NWRDMC as the whole of Government service provider, the consultant shall support MOWRAMs WRIS and NWRDMC staff to prepare and deliver end user awareness and user training to other Government and non-government data users.

Information Technology System Design and Operations Engineer (international 15 p-m)

The IT systems design and operations engineer fulfils the dual role of IT design engineer and IT operations engineer, focusing on (i) the planning and creation of IT systems (software and hardware), (ii) the maintenance and smooth operation of these systems.

The expert will have an engineering degree, a master's degree in information technology or an equivalent qualification and 10 years' experience in the planning, design and implementation of IT systems and networks (particularly with foreseen scalability requirements), deploying, maintaining, monitoring and troubleshooting IT systems, preferably in the field of water resource management, meteorology, watersheds and irrigation systems.

He/she has skills in server administration (Windows, Linux), as well as knowledge of network hardware routers and switches (Cisco, Huawei, Juniper, Arista, etc.) and firewalls (Fortinet, Palo Alto, Checkpoint, etc.). The expert is proficient in LAN, MAN, WAN, Wi-Fi and data centre networks, network protocols and standards (routed protocols, layer 2 protocols, static and dynamic routing, secure protocols, AAA, etc.) and some of the following software publishers or environments: Cisco, HP, Palo Alto and Infoblox. Finally, he/she has knowledge of virtualization tools (VMware ESXI, Citrix/XenServer), IT security (firewalls, authentication, secure protocols, etc.) and scripting languages (e.g. Bash, PowerShell, Python) to automate routine tasks and system processes.

The expert will have demonstrated the ability to work closely with stakeholders and have practical experience of working with cross-functional teams

The specialist will be responsible for:

(i)          Analyse the performance, security and reliability levels of the systems required to meet the functional needs of the WRIS (for both hydrology and meteorology),

(ii)        Define and document the network architecture (network architecture diagram) for the NWRDMC,

(iii)       Recommend appropriate technical solutions and providers, taking into account the performance/cost ratio,

(iv)       Design the communication system and supervise the construction of the network.

(v)        Design the functional and technical architectures of the WRIS to open and integrate the existing WRIS system based on Delft's FEWS with the Synergy Weather Forecaster Platform to enable continuity and consistency in the production of early warnings.

(vi)       Continue to develop the hydro component of the existing WRIS based on Delft FEWS, building on its architecture and design, including updating hardware, software, network and security components.

(vii)     Ensure the design and development of software tools for integrating the existing WRIS system based on Delft FEWS with peripheral systems such as FAO's IAMS and WAPOR, and the Weather Forecaster Platform in order to automate data flows within WRIS.

(viii)    Continue the development of existing WRIS systems based on Delft FEWS to ensure system security in accordance with best practices such as encryption, firewalls and identity management.

(ix)       Propose analysis and recommendations on cloud computing, cloud architecture, hybrid solutions and cloud migration strategies for the existing WRIS system based on Delft FEWS, including microservices, containers (Docker, Kubernetes) and serverless computing.
