Abstract
Water is a fundamental element in the economic and social development
of any country.
A survey of surface water development in the Upper Benue Basin is
made here in and availability of necessary data for water resources
development discussed.
A set of average monthly Temperature and Rainfall data have been
used to estimate monthly streamflow values at three gauging stations by
the Book keeping technique of the Climatic VJater Budget analysis. After
a few trials, each time using a set of values for VJater Holding Capacity
of soils and other factors of the Budget analysis, monthly streamflow
values were arrived at which compare favourably with corresponding
observed (measured) strcamflows at the gauging stations.
Another set of Temperature and rainfall data is then used in
conjuction with the final set of values of VJater Holding capacity and
other factors like overland runoff (Direct Runoff) and channel conveyance
coefficients to estimate monthly Runoff for three consecutive years
at one of the gauging stations.
The result of this exercise shows that the Climatic VJater Budget
method can be reliably applied to the various sub-basins of the Benue
River to estimate streamflows from rainfall data
