Chapter 4 Hydrogeology CHAPTER 4 HYDROGEOLOGY
The Development study on water resources development and management for Lake Kyoga Basin Final Report -Supporting- Chapter 4 Hydrogeology CHAPTER 4 HYDROGEOLOGY 4.1 Collection of Existing Data Existing data about hydrogeology managed by Directorate of Water Resources Management (DWRM) are Groundwater Database, Mapping Project data, and Groundwater Monitoring data. Others are the MIS database which is water supply facilities database managed by Directorate of Water Development, including the items of location, water source, functionality, and so on. 4.1.1 National Groundwater Database (NGWDB) This database was established by DWRM with contracting to a local consultant in 2000. DWRM had been compiled database based on the “Borehole Completion Report” which is submitted by drilling company after completion of drilling. In 1990s, it was managed by database software on MS-DOS, and before 1990s, it was borehole ledger described on paper book. Now it was compiled by Microsoft Access database management software on the Windows base again. Figure 4-1 shows the initial display of the database. The database has been input the data based on the completion report submitted by drilling company every year. It is including the well specification, geological information, pumping test data, water quality test result, and so on. This database is very sophisticated. DWRM gave to the study team the Source: DWRM data which are related to the Lake Figure 4-1 Initial Display of National Groundwater Database Kyoga Basin. In the obtained data, the number of data which described the registered well number is 11,880, the number of data which described the well construction information is 9,672, the number of data which described the hydrogeological information is 5,902, the number of data which described the pump information is 1,095, and the number of data which described the water quality is 2,293.
