4. Study Area CEB

5. Role of Groundwater in Namibia´s water supply

6. History of data management
• Started with Spreadsheets in the late ´70s
• Early ´90s DOS based server was introduced,
breakdown 1998 with huge data loss
• Since 2004 GROWAS I, breakdown with data loss in
2009
• Since 2011 development of GROWAS II

7. Improved Database GROWAS II
 Userfriendly  Spatial Queries, adaptable multiple parameter
display, Google Earth
 Adapted to Namibian requirements: Workflow analysis, Water
Act  Modules
 High Quality Management Standards (Look-up tables, Google
Earth, “Fosterage” – temporary data  confirmed, Reliability
“traffic light”)
 Regional conformity (Lithological Keys)
