Nuclear attenuation of the leading ({ital x}{sub {ital f}}{gt}0) hadron and the nuclear enhancement of target fragmentation ({ital x}{sub {ital f}}{lt}0) hadrons in lepton-nucleus reactions are calculated via a (3+1)-dimensional string-parton model. A (1+1)-dimensional string model is used to investigate the dependence of rapidity distributions on the lepton energy loss, {nu}=10--100 GeV, the atomic number, {ital A}=1--200, the effective string tension, {kappa}=0.5--2 GeV/fm, the string decay constant, {tau}{sub 0}=0.5--2 fm/{ital c}, and the string flip cross section, {sigma}{sub {ital l}{ital q}}=0--30 mb. The (3+1)-dimensional string-parton model includes inelastic final state cascading of produced hadrons in the nucleus. We show how the {ital A} dependence of hadronic production in lepton-nucleus collisions, especially in the {ital x}{sub {ital f}}{lt}0 region, may be used to extract information on quark propagation and hadronization in nuclei.
