No consideration <br /> <br />has been given to physical parameters which might make a considerable <br /> <br />difference in the response mechanism and resultant damages. As an <br /> <br />. <br /> <br />example, it is well estahlished that soils in the Imperial Valley are <br /> <br />heavy in texture which leads to problems in drainage.
