Gravity and magnetic field datasets coupled with Shuttle Radar Topography Mission (SRTM) digital elevation data over north-western Nigeria were interpreted to delineate subsurface and surface structures, and determine their influence on the drainage system within Sokoto Basin and its surrounding environment. The Improved Logistic Filter and Euler Deconvolution techniques were applied to the residual fields of the gravity and magnetic data to delineate lineaments and their depths of occurrence, respectively. The lineaments mapped from gravity and magnetic data revealed a major N–S and NE–SW, and W–E trend respectively and in several cases were aligned with surface lineaments from the SRTM digital elevation data. The results revealed that the drainage channel of Rivers Niger, Sokoto, Rima, Zamfara, Ka, Kasanu, Gagere, Kuromoni, Malendo and Kontagora are closely aligned with several lineaments emanating from the underlying basement. The 2-D forward models confirmed the presence of these lineaments and delineated intrusives within Sokoto Basin. This study concluded that the drainage system of north-western Nigeria is structurally controlled.
