description | The research carried out in alo-pohu watershed gorontalo province aims at
identifying the effect of watershed conditions and land use on the amount sheet
erosion, sediment yield and sediment delivery ratio. It is also intended to develop
them in a spatio-temporal distribution, and give recommendation for management
of environmental condition and land use in alo-pohu watershed to prevent damage
erosion and sediment. Data on environmental condition and land use were
collected by interpreting landsat images and topography map. Data on surface
erosion were obtained by means of direct measurement using 10 erosion plots
placed in the land units. Data on sediment were obtained by collecting water
samplesfrom the upper course, middle course, and lower course of the rivers. Data
on sheet erosion and.sediment yield were analyzed in a spatio-temporal manner
using geographic information systems (gis) and effect of watershed conditions and
land utilization on sheet erosion, sediment yield, and sediment delivery ratio are
tested using double regression analysis. The research results suggest significant
effect of watershed conditions and land use on sheet erosion. the largest amount of
erosion very likely occurred in wasteland (bero land) with steep slopes whereas the
least amount of erosion was found in undergrowth with flat slope (0-8%). the
amount of sheet erosion was 122.24 ton/ha/year. sediment yield in alo-pohu was
affected to a large extent by runoff rate, the width of watershed, percentage of
wasteland, and drainage density. |
