Abstract
The hydrological characteristics of this small catchment
basin which is essentially an agricultural land are described
and the available climatic data examined. One of the methods
by which climatic picture may be created is by the averages of
the several climatic elements particularly thost. on precipitation
and temperature. This picture is presented in the form
of histograms. The analysis of the characteristics, origin
and distribution of the important elements which comprise the
climatic complex are presented.
During the rainy season the catchment basin is vegetative
providing protection from the impact of rainfall for the soil.
The soil cover and land use studies show that they are essential
factors in analysing the hydrological components. Owing to the
present system of land use, the observed surface runoff is low
though the runoff potential on the basin is high.
Determination of the changes in ground water storage was
accomplisaed from an adequate knowledge of the behaviour of the
water-table in the basin. The dry and wet season contour maps
prepared provide direct visual information relating to the
slope of the water-table. Depth to dry season water table can
be estimated at any point on the oatchment basin using a
simple formula evolved. It is only during the dry season
that the entire population of Bomo village appreciate fully the
ground water resources for their needs.
In solving the equation of the hydrologic equilibrium,
advantage was taken of the basin' s ground water and climatic
characteristics
