Incidence of flood has been on the increase in Ilorin for sometime; and this exemplifies the problem operating in most urban centres in Nigeria. Increase in runoff production in an urbanized catchment is a function, among other factors of to increase in percentage paved area brought about by deforestation activities and poor environmental attitude of the people. This study examines the relationship between runoff discharge and basin characteristics in Ilorin. Data used were collected directly from the field over a period of one calendar year. Rainfall data were collected in each basin using a standard rainguage of 20cm orifice while basin discharge was collected twice daily (8.00am and 6.30pm) using fabricated staff gauge graduated in centimeter. Basin morphometric attributes were compu...

His goal in the beginning was "to grow as diverse a variety of fruit trees as our climatic conditions would allow and those climatic conditions are evolving as we speak," he added. What is possible to grow is anything with a temperate Mediterranean or sub-tropical origin," said [Bob Duncan]. The dwarf fruit trees are growing at an angle along a framework, their branches spaced evenly to maximize their fruit-bearing potential. Duncan calls the setup "a fruity wall.
