PhD Research Theme

• The aim of my PhD is to assist water managers in semi arid regions by development of a seasonal hydrological forecasting system prototype. The prototype would forecast basin hydrology at 1 to 6 months lead time which would facilitate the water managers (mainly dam operators & farmers) in their decision making. My funding project - Seasonal Water Management (SaWaM) (https://www.ufz.de/index.php?en=43217) - encompasses eight basins in five focus regions (Brazil, Ecuador, Iran, Sudan, West Africa) across three continents.

• With large fluctuations in annual precipitation, one of the key anthropogenic feature of semi-arid regions is seasonal storage and use of water. A reliable hydrological forecast system at such regions require accurate representation of the existing and planned lake/regulated-hydrology systems. In this regard, the first objective of my PhD is improvement of the in-house mesoscale hydrological model (mHM, https://www.ufz.de/index.php?en=40114) with development of mHM lake module (mLM).
  

• Once mHM is equipped with mLM, calibration and development of validated models for each project regions is my second objective.

• Finally, the end product of my PhD research is envisaged to be the development of an end-to-end seasonal forecasting system. This model chain system will have mHM at its core, where ensemble of seasonal meteorology forecast is fed into mHM and the resulting ensemble of seasonal basin hydrology forecast is made available (online) for the water managers of the SaWaM regions.
