We consider the entropy solution u of a scalar conservation law in one-space di- mension. In particular we prove that the entropy dissipation is a measure concen- trated on countably many Lipschitz curves. This follows from a detailed analysis of the structure of the characteristics. We will introduce a few notions of Lagrangian representations and we prove that characteristics are segments outside a countably 1-rectifiable set.
