SUMMARY:Heavy Rainfalls in a Desert(ed) City – a climate-archaeological 
 case study from Naga\, Sudan - Dr Jonas Berking

DESCRIPTION:In the semi-arid region along the fringe of the north-eastern 
 Sahel and the eastern Sahara desert\, about 150 km north of Khartoum and 4
 0 km south of the Nile\, the remains of this Meroitic city Naga are locate
 d. During its heydays the city has been a highly developed central place\,
  with a high population and an economic culmination from about 300 BCE to 
 300 CE. Naga is the target of archaeological research since several decade
 s and since 2008 of geoscientific investigations. The main construction in
  Meroitic Naga\, the “Great Hafir of Naga”\, was built around the turn
  from BCE to CE to collect surface runoff. This study is an approach to in
 vestigate the ancient water harvesting measures\, focusing on the relation
  of the\nwater availability and the water storage capacity. Work on hydrol
 ogical and climatological questions in the regions involves typical proble
 ms of drylands: the catchments of the wadis are ungauged\, climate data ar
 e spatially and temporally fragmentary and information on the physical cha
 racteristics of the catchment is either scant or coarsely resolved. Moreov
 er\, rainfall and runoff are spatially and temporally highly variable\, so
  that quantitative estimations of present and to an even greater extent\, 
 past climatological and hydrological processes are problematic. The contri
 bution aims to present the concept\, background and results of an approach
  to cope with these challenges and to model the catchments' rainfall-runof
 f relationships including the behavior of the water supply systems of the 
 ancient city of Naga.
