Proceeding of the Joint International Symposium on Deformatuon Monitoring. 2-4 November, 2011. Hong Kong. China. Report. Soil erosion has become one of the most serious environmental problems all over the world. This is as a result of the fact that a large volume of land area which would have been used for development of infrastructure and residential area is lost in urban areas while large agricultural land is lost in rural environment. Gully erosion removes large volumes of soil from an area. Gully erosion is attracting great interest by scientific communities. In this study the position of all major rill and gully sites were located and Georeferenced using Hand held GPS receiver. Based on severity rating and geopolitical considerations, six of the erosion gully sites were selected for monitoring and Control points were established around each of the gully sites by method of Differential GPS (DGPS) surveys and detailed topographical survey of gully sites carried out using reflectorless total station instruments. Using SPOT imageries in combination with GIS and total station data, the location maps, contoured maps along with DEM were generated using ARCGIS 9.2 software. The morphological parameters of the gullies including depth, width, length and areas of the gullies were then determined. Volumetric estimate of the amount of soil loss from gully erosion was also carried out. Soil samples were recovered from the gully sites to determine their erodisivity and other properties to be used for soil loss modeling. The result of the studies was used as an indicator for determining the gully initiation point slope-Area relationship, and threshold of gully initiation was also established. The maximum volume of soil loss occurred in gully No 2 (Queen Ede College). The minimum AS2 value was 345 while the maximum was 3,267. This shows that the results lie within the two boundary layers of 41 and 814 (m2) and 500-4000 m2 established by Poesen et al , Montomery and Dietrich respectively.
