Flood hazards, their impact, and the resilience of communities have been assessed here on three spatial scales – national at macro level, watershed at meso level, and village development committee/municipality at micro level. At national level, the impacts from different environmental hazards have been assessed, whereas at watershed level the focus was on hazard, risk and vulnerability mapping. The Ratu watershed in the central Terai (Mahottari and Dhanusa districts) was selected for mapping. At micro level, the focus was on enhancing the resilience of local people to cope with and recover from flood hazard. Rajbas in the upstream area and Jaleshwor Municipality in the downstream area were selected for micro level activities. A geomorphic approach (GIS and RS), measurement of rainfall-runoff processes using the hydrological engineering corporations river system analysis (HEC-RAS) model, and social flood hazard mapping based on local experiences, were used. The main sources of information were maps, aerial photographs, satellite image, household survey and group discussions, field observations, and published and unpublished documents. GIS based software’s, such as Arc view, The Integrated Land and Water Information System (ILWIS), and the Hydrological Engineering Corporation’s River System Analysis (HEC-RAS) were used for data processing and analysis.
