Simultaneous magnetization, resistivity, and {ital I}-{ital V} measurements on YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} show the relationship of the thermodynamic and dynamic behavior near the vortex lattice melting line. We find a coexistence region of solid and liquid at melting, with a first order magnetization jump which is independent of the vortex velocity. Sudden jumps and time dependent hysteresis of the {ital I}-{ital V} curve in the vortex solid phase are interpreted as a relaxation-pinning effect. {copyright} {ital 1996 The American Physical Society.}
