Abstract:
Rwanda is rapidly developing after the 1994 genocide. This development is highly
concentrated in the Nyabugogo catchment where Kigali City is located. Water resources
planning and management is an important component of development processes and
therefore its integrated management is required to assure effective long term development as
regards to social and economic development; however there is limited knowledge in
assessment of the Integrated Development and Management of Water Resources for
Productive and Equitable Use in the Nyabugogo wetland.
The main objective of this study was to assess the alternative means for increasing
productivity of water, through better management of multiple water uses in the Nyabugogo
catchment. Precipitation, evaporation data were obtained from Meteorological office in
Kigali, Flow/ discharge used were computed and were obtained from integrated water resources management department of Rwanda natural resources authority and run –off data
estimates were computed and used and a delineated map using ArcGIS was used to calculate
the wetland area.The percentage of land use in the catchment is distributed as follows:
agriculture 88.65%, forest 3.99%, urban area 1.93%, wetland 3.39%, and Lake 2.04%and this
is almost the same in the wetland area of the studya digitized land use map and hydrological
soil group classification of the catchment were used to estimate the runoff coefficient of
nyabugogo wetland.
Storage capacities, increased water losses from increased evaporation, increased surface run
off were found to be the dominant features of the wetland.
