Soil and water conservation issue is one of the most
important environmental challenges for climate
change and land degradation processes in arid and
semi-arid regions of the century. Many waterharvesting
techniques have been developed so far to
face these challenges. In this technique, the
components of constructions directly affect the water
runoff and water quantity and indirectly affect the
soil loss amounts by water erosion.
In this study, we tried to find out that the most
important constructional parameters of the jessour
which is a traditional water harvesting technique
known from the Roman occupation for soil and water
conservation attempts in the arid regions. This study
was performed in the micro-watershed of El-Jouabit
in Matmata mountains in the southeast of Tunisia
Totally, 620 Jesr and 9 construction parameters were
evaluated, such as; length of the terrace of the Jesr
(m); width of the terrace of the Jesr (m); height of
retention (m); height of the tabia (m); length of the
tabia (m); capacity of retention (m3); surface of
retention (m2); surface of the impluvium (m2) and
number of planted trees). As a result, 4 parameters
were found as the most important to ensure the best
performance of this technique which is the height of retention, the capacity of retention, the surface of
retention and surface of the surface of the impluvium
