Özet

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
