  Increases in the frequency of large to extreme rainfall events are widely predicted with global warming, but evidence from the humid tropics is hampered by a paucity of long-term data. This paper assesses changes in daily rainfall magnitude–frequency and their geomorphological consequences in the equatorial environment of northern Borneo using (1) rare daily rainfall data series for 1906–2012 assembled from archival and current sources and (2) ge…

• Historical Changes in the Flood Hazard at Khartoum, Sudan

  The 1988 floods at Khartoum were frequently described as “unprecedented”. However, an examination of evidence for floods caused by the Nile and rain storms during the nineteenth and twentieth centuries leads to the conclusion that neither the Nile flood nor the rain storms nor their coincidence in one season were unprecedented and that similar situations will recur.We argue that most problems were created by complacency, lack of planning and mism…

• Flood Frequency and Impacts at Khartoum since the Early Nineteenth Century

  The nature and history of flooding problems at Khartoum since the early nineteenth century are examined using archival flow and river height records and historical documentary sources, putting the 1988 floods into historical perspective. Three genetically distinct types of flooding are identified: Nile floods; flooding of local ephemeral watercourses; and flooding of streets and houses by urban run off. The magnitude and frequency of Blue Nile fl…

  1980s, with 1984 the driest year on record and all annual rainfalls from 1980 to 1987 well below the long-term mean. In White Nile Province annual rainfall in 1965-84 was 40 per cent below 1920-39 levels; wet season length has contracted by 39-51 per cent; and the frequencies of both large and minor daily rainfalls have declined by up to 51 per cent. Hydrological consequences in North West White Nile have included reduced frequencies of wadi flow…
