The　one-dimensional　steep　slope　shallow　water　equations　are　used　to　model　the　dam-break　flow　down　a　uniform　slope　with　arbitrary　inclination,　and　analytical　solutions　are　derived　by　the　hodograph　transformation　and　the　Riemann＇s　method　in　terms　of　evaluated　integrals.　An　implicit　analytical　solution　is　obtained　to　evaluate　the　spatio-temporal　distributions　of　dam-break　flood　hydrographs　along　the　slope.　For　convenience,　the　solution　for　representative　wave　profiles　and　velocity　distributions　is　shown　in　charts.　Comparing　with　the　Dressler＇s　solution　and　WES　experimental　data,　the　analytical　solution　is　seen　reasonable.　©　2015　Publishing　House　for　Journal　of　Hydrodynamics.
