As the water scarcity problems is increased in arid and semi arid zones, the rainfall water harvesting is very important technology required to overcome water shortage and food security.
The selection of the best locations of water harvesting was affected by land use/land cover, and the soil infiltration rate. So it is very important to select the best method to find infiltration rate, among many methods like rainfall simulator, double ring device, .... etc.
Greetings!
Best method that could be practically applicable for such a design is Artificial intelligence models. However, you need to have valid & sufficient dataset of the investigated catchment in addition to the hydrometeorological dataset of the region. In this way, it can be easily implemented to identify the accurate infiltration rate.
your asking particularly arid and semi arid region, there are maximum loose soil and cannot store water in it and also receive less rainfall.my suggestion can you try to save rainwater in non porous area by constructing check dams and can use in summer
Please identify the area that have soils with more than 10 mm per hour saturated hydraulic conductivity(sHC). sHC can be conveniently determined in the laboratory using a constant head permeameter (Richards 1954).

There is no satisfactory method for all field conditions. The available supplies and the availability of suitable materials and equipment determine the method must be used.
