  abstract = {{I}n the middle {S}enegal valley, the saline soil distribution is not related to the present faint topography. {T}he absence of a relationship is one of the major constraints in establishing new irrigation schemes. {T}he salt distribution was studied to understand its variability, and to describe its structure and spatial arrangement. {S}aline areas were delineated by measuring the electromagnetic soil conductivity ({EC}m), a rapid technique with a portable instrument ({EM}38). {T}he results indicate that the saline soils are distributed as strips. {A} detailed examination revealed that the major strip is actually composed of two parallel minor strips, and a comparison with aerial photographs showed that one lies in a former creek bed, and the other fringes it on the southern bank. {T}he strip is intersected by an actual creek bed, indicating that the salt distribution is ancient, related to previous geo-morphology, and does not result from a recent remobilisation of the marine salt deposits incorporated in the soil. {T}he identification of this relationship between the present saline soil distribution and previous geo-morphology allowed us to survey the whole {N}'{G}ualenka region (about 6000 ha) using {EC}m measurements on selected transects.
