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. |
