t.is paper present. a preliminary assessment.of.t.e hydrogeological charact.rist.cs of.a k.rst.mount.inous cat.hment. t.e Suoi Muoi River cat.hment. in t.e nort.west.of.Viet.am. t.e cat.hment.is locat.d at.600–700 m a.s.l. and covers an area of.284 k.. Exposed limest.ne occupies 32% of.t.e t.t.l cat.hment.area. Various t.pes of.assessment. have been carried out. including geological and hydrogeological f.eld surveys, cave surveys, dye-t.acer t.st., met.orological and surf.ce wat.r monit.ring. Geological st.dies and cave surveys have ident.f.ed t.e most.import.nt.act.ve cave/conduit.syst.ms wit.in t.e cat.hment.
