An SDUH model was developed using digital DEM elevation data and land use data collected during a field survey. The SDUH model was applied to a 5km2 agricultural watershed in the Upper Athi river region of the entire Athi river basin. The USGS DEM (30-m) resolution was used to estimate the slope, aspect, flow distance and upstream area for each cell. The watershed was divided into "overland" and "channel" flow cells based on the area upstream ...

Sampling, which is supposed to provide adequate and unbiased representation of a study interest, is often faced with challenges such as choice of the minimum cost-effective sampling size, accurate location of sampling sites and statistical justification of both location of the sites and accuracy of the sampling process. Although there are many statistical sampling protocols in the literature, they largely emphasize on accuracy tests for unbias...
