\begin{abstract}
Tectonically beheaded valleys represent strain markers that can be used
to constrain the geometry and kinematics of dip-slip faults. Quantifying
the cumulative deformation they have recorded requires introducing
several assumptions that are difficult to test, which limits their
practical utility. Here we present a new method which eliminates some of
these assumptions by focusing on pairs of beheaded valleys and analyzing
them in the chi (horizontal channel coordinate normalized by drainage
area) -- elevation space. This approach allows tectonic deformation to
be retrieved without using any information from the lost upstream
catchment, and has therefore the potential of reducing uncertainties
associated to the tectonic reconstruction of beheaded valleys. We
demonstrate the power of this method by applying it to an outstanding
beheaded stream network preserved across the Wadi-al-Akhdar Graben (NW
Saudi Arabia). This methodological contribution is expected to revive
the use of beheaded valleys by morpho-tectonic studies, and stimulate
the exploration of its potential for long-term tectonic reconstructions%
