settlement Floodplains and piedmonts North Bihar and the Nepal Tarai combine Himalayan piedmont, alluvial fans, active channels, wetlands, and older floodplain surfaces. Settlement opportunity and archaeological visibility are both conditioned by this geomorphology. A mound may preserve repeated occupation while nearby low surfaces are scoured or buried. The absence of exposed remains is therefore not equivalent to absence of past population. Mobility alongside village life Fishing, herding, seasonal movement, woodland use, and river transport continued alongside settled cultivation. Later administrative sources often treated mobility as disorder because it complicated taxation and surveillance. Prehistoric reconstruction should avoid the same bias: mobility can be a rational adaptation to variable water, pasture, and labour demand. The environmental caution Neither flood nor drought is purely 'natural' in its historical effects. Exposure is shaped by embankments, land tenure, settlement policy, transport, and unequal access to relief. This principle, documented clearly for the Kosi in the colonial and modern periods, also guides interpretation of earlier settlement without pretending that later institutions existed in prehistory. A connected river system The northern tributaries of the Ganga descend rapidly from Himalayan catchments, cross the piedmont, and spread across low-gradient plains. Their channels carry water and sediment while shifting through time. The result is a mosaic of active channels, levees, backswamps, abandoned courses, and older surfaces. Communities could benefit from fertile deposits, 53 fisheries, transport, and moisture while remaining exposed to erosion, avulsion, waterlogging, and crop loss. The historical importance of the Kosi, Gandak, Bagmati, Kamla, and related rivers lies not in a single unchanging course but in the opportunities and hazards created by a mobile system. Seasonality and the organization of work Monsoon rainfall and river regimes shaped calendars of sowing, harvesting, fishing, grazing, building, and movement. Labour demand could vary sharply across the year, encouraging households to combine cultivation with craft, transport, forest use, or seasonal migration. Archaeology rarely preserves this calendar directly, yet botanical remains, animal assemblages, storage, house rebuilding, and site location can provide
