  abstract = {{I}n this study, an assessment of similarity relationships across runoff measurements at various spatial scales was carried in a typical {S}ahelian landscape, under semi-arid climate in northern {B}urkina {F}aso (west {A}frican {S}ahel). {T}he scales of observations considered are the plot scale (1 m2, 50 m2, 150 m2) and the sub-catchment scale (6.1 ha, 33.8 ha), with various soil surface conditions and slopes. {T}hese scales were monitored during six years (2010-2015) under natural rainfall. {B}ased on monitoring data, a runoff potential index {I}1 and an effective runoff index {I}2 are developed, encapsulating the physical characteristics of the observation scale into dimensionless forms, hence reducing their sensitivity to the scale effects. {T}hese indices help in assessing hydrological similarity across measurement scales. {R}esults showed that runoff decreases with the increase of the observation scale size. {B}esides, dimensionless indices vary following a logarithmic decay relationship with the scale size ({R}2 > 0.98). {S}uch results highlight the non-linear nature of runoff processes and also promotes similarity analysis as a means to model hydrological processes through soil surface conditions and landscape descriptors.},
