摘要

The elements of water budget equation were analyzed for the Agulu lake area and underlying aquifers. The water budget implications for soil and gully erosion were evaluated in relation to the geological formations and hydrogeotechnics. Results show that rainfall constitutes the main source of precipitation. It ranges from 1714.04mm to 1995.53mm annually. The potential groundwater aquifer volume is 1.5 X 10~7m~3. Discharge from aquifers contributes 7.4 X 10~7m~3 water annually. The amount of 1.72 X 10~5m~3 that is 60% of precipitation is lost to evaporation; 17 to 21% to infiltration. The quasi steady state of the lake water level and volume shows surface and groundwater continuity as explained by the small difference between total input and output values of the computed water budget of the lake and the aquifer. Flood studies indicate that 19.5% of the annual precipitation constitutes runoff, the main agent of gully and soil erosion, flooding and landslides. The other factors that control the distribution and location of gullies arc tithologic and strati graphical, while topography/gcomorphology controls gully distribution within various geologic units. A typical gully is about 500m X 50m X 30m long, wide and deep respectively. The destruction to life and property by runoffs/floods demands joint and sustained efforts by the community dwellers.
