FEATURES OF NATURAL HYDRATION BY THE TYPES OF ARABLE LAND LOCATIONS OF THE SANAA BASIN

Abstract

The aim of the study is to study the possibility of obtaining agricultural products from dry lands in arid climatic conditions of mountain areas, depending on natural moisture availability. The concept of types of arable land locations was introduced. The entire variety of locations of arable land in the Sanaa basin is divided into five types of locations depending on the location of a particular one or another form and relief element. The characteristics of the types of locations of the main wadi, intermountain basin, plain and other forms of relief of the Sanaa basin are given. The methodology for assessing the natural moisture availability of the types of locations of arable land of the main landforms was developed. Based on the materials of experimental field work on drain-forming sites and literary sources, the values of the runoff coefficients of the exits of indigenous rocks, loose eluvial, deluvial-proluvial and alluvial sediments of arable lands were determined and adopted for the calculation of natural moisture availability.
