Nepal is the birth place of Bagmati river. The river flows from north to south direction in Nepal and to east direction in Bihar. Drainage patterns also display in the structural and litho logical control on the evolution of landforms. Drainage Pattern refers to the particular design which the stream course collectively form channel patterns such as meadering braided, straight etc. The study of drainage pattern assets in the interpretation of the nature of the terrain. "The pattern of drainage is one of the most refeiling features of a landscape that cast light on the rocktype Geological structure stage in drainage evolution etc." The pattern of developed over an extensive area in Bihar region mostly in the specific areas of granite, mica, shale and phyllite offering relatively uniform resistance. The pattern of drainage that then ensures in dendritic, having stem, branches, limbs and twings, it is like an oak tree in the organization of its part. The drainage pattern generally discards structural control. But the trunk like courses of the lower Bagmati for more than 25 Km. The lower courses of the tributaries and many independent tributaries run parallel to the other before their conflux with the master stream and tributaries are so small as to make the major and subsidiary stream nearly parallel.
