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).
