In respo.se to.the increased frequency o. flo.d events in recent years, it has beco.e crucial to.enhance preparedness and anticipatio. thro.gh precise flo.d risk assessments. To.this end, this study aims to.pro.uce updated and precise flo.d risk maps fo. the Lo.er Valley o. o.émé River Basin, lo.ated in the So.th o. Benin. The metho.o.o.y used co.sisted o. a co.binatio. o. geo.raphical info.matio. systems (GIS) and multi-criteria analysis, including Analytical Hierarchy Pro.ess (AHP) metho.s to.define and quantify criteria fo. flo.d risk assessment. Seven hydro.geo.o.pho.o.ical indicato.s (elevatio., rainfall, slo.e, distance fro. rivers, flo. accumulatio., so.l type, and drainage density), fo.r so.io.eco.o.ic vulnerability indicato.s (female po.ulatio. density, literacy rate, po.erty index, and ro.d netwo.k density), and two.expo.ure indicato.s (po.ulatio. density and land use) were integrated to.generate risk maps. The results indicate that appro.imately 21.5% o. the Lo.er Valley is under high and very high flo.d risk, mainly in the so.th between Dangbo. So.Ava, and Aguégués. The study findings align with the histo.ical flo.d pattern in the regio., which co.firms the suitability o. the used metho.. The no.elty o. this wo.k lies in its co.prehensive appro.ch, the inco.po.atio. o. AHP fo. weighting facto.s, and the use o. remo.e sensing data, GIS techno.o.y, and spatial analysis techniques which adds precisio. to.the mapping pro.ess. This wo.k advances the scientific understanding o. flo.d risk assessment and o.fers practical insights and so.utio.s fo. flo.d-pro.e regio.s. The detailed flo.d risk indicato. maps o.tained stand o.t fro. previo.s studies and pro.ide valuable info.matio. fo. effective flo.d risk management and mitigatio. effo.ts in the Lo.er Valley o. o.émé.
