Aymen

lot of information is readymade available on net/ web. Two important points I would like to put before you,

1. average infiltration rate is not so good to get used, rather better you opt either for steady state infiltration rate or for rates during initial few minutes duration; else it becomes a kind of phi-index which improperly reflect this important hydrological loss function.

2. The exact location, land use , and other location specific physiographic conditions are extremly important , hence better you reflect these attributes , to get appropriate sets of asked values. Infiltration is highly variable in space and time domain.

wish you all the best

Dr Gaur 

Information from Somnagouda are very good to start with...

Somanagouda,

As you are going to carry out a simulation, I dont recommend to use tabulated values. As Gaur has mentioned,  infiltration rate is one of a highly varied soil physical parameter, especially lands which are highly exposed to human activities.  Best way is get the field measurements using double ring infiltro-meter. you can find detailed methodology of it from FAO inline of previous technical papers on irrigation and drainage from same agency. Anyway, if you dont like to do so, use "NRCS - surface" or SURMOD 111" software that you can freely download from USDS NRCS web site. it has included typical infiltration curves for different soil texture types. if you cannot find the software, i can provide you which I downloaded few years back. probably it will not be the updated version. 

best regars

Dear respected Aymen Al Al Baaj,

I have article on average infiltration rate for soil exposed to different tillage operations. The soil analysis for the infiltration rate is sandy soil. You can check this article.

Hope it would help.
