Abstract
Stream discharge and soil characteristics were
evaluated on an experimental field for ten months. Calibrated
rectangular weir was used to monitor stream discharge and sieve
analysis was used to characterize the soil. Findings indicated a
sandy loam, clay loam, and clay soil types at 0-60cm, 60-90cm, 90-
120cm profile depths respectively .A range of 6.29 - 27.75%, 1.04 –
1.80g/cm3 , 15.19 – 49.42% and 8.38 – 34.74% were established for
moisture content, bulk density, porosity and available moisture
content respectively down the profile ( 1 – 120cm) .Infiltration
decreased from 0.2 to 0.07 cm/min and 0.25 to 0.025 cm/min at
lower and upper fringe of the valley respectively. Stream
discharge is highest in October with peak value of 41.897l/s and
monthly average of stream discharge was 12.641l/s with only
67.7% of the storm depth translating to stream discharge. The
discharge hydrograph exhibits a close nested multi-peak. These
finding therefore, are viable information system for irrigation and
drainage practices on land and also useful in land and water
resources planning.
