  abstract = {{R}iver meander migration is a process that maintains biodiverse riparian ecosystems by producing highly sinuous rivers, and oxbow lakes. {H}owever, although the floodplains support communities with fish and other practices in the region, meandering rivers can directly affect the life of local communities. {F}or example, erosion of river banks promotes the loss of land on community shores, while sedimentation increases the distance from house to the river. {T}herefore, communities living along the {J}urua {R}iver, one of the most sinuous rivers on {E}arth, are vulnerable to long-term meander migration. {I}n this study, the river meander migration was detected by using {L}andsat 5-8 data from 1984 to 2020. {A} per-pixel {W}ater {S}urface {C}hange {D}etection {A}lgorithm ({WSCDA}) was developed to classify regions subject to erosion and sedimentation processes by applying temporal regressions on the water index, called {M}odified {N}ormalized {D}ifference {W}ater {I}ndex (m{NDWI}). {T}he {WSCDA} classified the meander migration with omission and commission errors lower than 13.44% and 7.08%, respectively. {T}hen, the number of riparian communities was mapped using high spatial resolution {SPOT} images. {A} total of 369 communities with no road access were identified, the majority of which living in stable regions (58.8%), followed by sedimentation (26.02%) and erosion (15.18%) areas. {F}urthermore, we identified that larger communities (>20 houses) tend to live in more stable locations (70%) compared to smaller communities (1-10 houses) with 55.6%. {A} theoretical model was proposed to illustrate the main impacts of meander migration on the communities, related to {I}nundation, {M}obility {C}hange, and {F}ood {S}ecurity. {T}his is the first study exploring the relationship between meander migration and riverine communities at watershed-level, and the results support the identification of vulnerable communities to improve local planning and floodplain conservation.},
