The article of the scientist of the Institute of Geography, Doctor of Geography M.A. Abduyev,
titled “Regularities of spatial distribution of the ion effluent module in Azerbaijani Mountain Rivers was published in the regular issue of the magazine “Meteorology and Hydrology”. With the exception of Lankaran region, the author shows other areas of growth in the vertical direction of the ion flow module. He proposes to identify module of ion effluent of rivers by using M=f(H) relations, where chemical streams are not observed.
