โœฆ Synopsis


Hydrological and water-quality measurements were made on a 44 . 3 ha watershed under forest cover and following deforestation and conversion to an agricultural land-use. Under secondary tropical rainforest, water yield ranged from 2 . 2 per cent to 3 . 1 per cent of annual rainfall. Deforestation of 7 per cent of the watershed area increased water yield to 7 . 0 per cent of annual rainfall. Baseยฏow increased with deforestation, and increased progressively with time after deforestation. It was 5 .

Field runo plots were established in 1984 to evaluate the eects of slope length on runo, soil erosion and crop yields on newly cleared land for four consecutive years (1984ยฑ1987) on an Alยฎsol at Ibadan, Nigeria. The experimental treatments involved six slope lengths (60 m to 10 m at 10-m increments)
