Abstract EN

The study area which extends over the hydrological basin of Wadi Fuada and the Lower reach of Wadi Al-Ubaiydh covers an area of (8400) km .

It represents part of the discharge zone of a much wider Razzazah depression basin.

The area is recognized by a low topographic relief with an inclination towards the east.

the geological stratas have also a small dip less than one degree west-east.

Field activities which took place between September (2011) and March (2012), during many visits, included water points inventory of (30) wells and the collection of models for a number of water wells penetrate formations.

Umm Er Radhuma and Dammam for choose Index Wells.

Those models were analyzed for water Hydrochemical data.

For the purposes of reducing the time and cost we can keep a small number of control points (wells, for example) to represent a much larger number of them through relationships relational statistical and this process needs from a number of readings or data that enable the creation of those relationships.

The Hydrochemical data of wells was Modeling and two ways have been used in building the model the relative and relational.

When applying the model show that he effectively with a relative error of less than (10%).
