Background and objectives of the position The Mekong River Commission (MRC) is the intergovernmental organisation established under the 1995 Mekong Agreement, mandated to promote and coordinate the sustainable management and development of the Mekong River Basin's water and related resources. The MRC facilitates dialogue and cooperation among its Member Countries, promotes joint planning and data sharing, and supports compliance with basin procedures to ensure equitable and sustainable development across the basin. The Mekong River Basin is experiencing increasing pressures from land-use change, hydropower development, irrigation expansion, and climate variability. These drivers are altering sediment transport, nutrient dynamics, and salinity intrusion patterns, which in turn affect aquatic ecosystems, agricultural productivity, and the livelihoods of millions of people who depend on the river system. Addressing these challenges requires sound scientific evidence and improved analytical tools to assess basin-wide water quality and its response to natural and human-induced changes. To support decision-making, the MRC has developed and recently upgraded the MRC's Decision Support Framework (MRC-DSF), which integrates hydrological and hydrodynamic modelling and scenario-based simulations using the MIKE suite of models. While the upgraded DSF provides simulations of flows, reservoir operations, and flood and drought conditions, it currently does not include water quality or sediment processes, creating a gap in the assessment of sediment transport, nutrient dynamics, and salinity intrusion. In order to address this gap, the expert will focus on extending the MRC-DSF to include comprehensive water quality modelling, covering on sediment budgets, instream sediment, nutrient, and salinity intrusion.The expert will also conduct the sediment budget assessment based on this devlopped modules and  training and capacity building to MRC and member countries to ensure effective use, interpretation and sustainable application of water quality models. Through these efforts, the expert will strengthen scientific evidence for transboundary water management, scenario analysis, policy formulation, and implementation of the MRC Strategic Plan 2026–2030.   Expected outcomes   The expert is expected to deliver the following outcomes: ·     A harmonized and quality-assured basin-wide water quality (WQ) data, including sediment, nutrient, and salinity parameters, is established and maintained. ·     Water quality modelling and simulation tools for the Mekong River Basin (e.g., MIKE+, ECOLab, or equivalent) are calibrated, validated, and integrated with hydrological and hydrodynamic models. ·     Analytical reports and model-based assessments inform regional and national decision-making on sediment and nutrient management and salinity control. ·     Enhanced capacity for both MRCS and MC  national modelling and monitoring teams to operate and maintain WQ models. ·     Technical inputs provided to basin indicators, the State of Basin Report (SOBR) and Basin Development Strategy (BDS).   Deliverables and responsibilities Under the management direction of the Division Director and technical advice of the Chief Hydrologist, and in close collaboration with the other Modeller, the expert shall be responsible for delivering the indicative outputs and tasks.

Background Delivering sustainable and reliable water in Afghanistan is increasingly challenging due to rising demand and declining availability. Population growth, unsustainable use, weak protection of water sources, and climate change are straining resources and increasing water insecurity for millions. Kabul's water crisis is one of the most striking cases. Currently 31.8% of Afghans lack access to basic drinking water. Erratic rainfall due to shifting climate patterns are reducing availability of surface water used for irrigation, pushing communities to rely more heavily on groundwater. This, combined with unregulated deep well drilling, is leading to widespread groundwater depletion, making monitoring a critical priority. Effective water management depends on reliable data. Yet , for the past 20–30 years, water monitoring has been limited due to insecurity and lack of access. Strengthening water data systems is essential for managing resources, reducing disaster risks, and supporting sustainable development. Since late 2022, UNICEF-Afghanistan has been actively working to strengthen groundwater monitoring. In April 2023, SDC began supporting this effort through a secondment of a hydrogeology expert. This collaboration has led to significant achievements: 1.   National assessment of Afghanistan's groundwater monitoring system; 2.   Development of the first national groundwater potential and vulnerability maps; 3.   Design and delivery of online and in-person training for UNICEF staff and sector stakeholders in GIS, remote sensing, and water resource mapping; 4.   Formulation of a National Strategy and Action Plan to strengthen water monitoring; 5.   Successful drilling of 49 new monitoring wells in the Helmand, Harirud-Murghab and Kabul River Basins, including capacity-building in drilling supervision; 6.   Installation of 100 dataloggers across six provinces and capacity-building for the related technicians in data collection, analysis and management ; 7.   Development of a methodology to identify areas suitable for Managed Aquifer Recharge and piloting of integrated climate-resilient water supply systems at the community level; 8.   Creation of a sector-wide Roadmap based on Integrated Water Resources Management (IWRM) principles.   Purpose Given the recognized need to continue supporting Afghanistan's water sector and to build on the progress achieved, UNICEF seeks to extend the collaboration through a new secondment.
