  • Altitudinal zonation of selected geomorphological phenomena in an alpine periglacial area (Abisko, northern Sweden)
  • The objective of this study is the search for an altitudinal zonation of geomorphological phenomena in a small, alpine, periglacial area. Because the Abisko region shows a large altitudinal range, a variety of geomorphological phenomena and a minor

  • Declining groundwater level of the Minjur Aquifer, Tebrak area, Saudi Arabia
  • The Tebrak area affords a typical example of the country's agricultural expansion and groundwater management problems. Since irrigated agriculture in the Tebrak area, as well as in most of the country, is mainly dependent on groundwater, the purpose
  • of this paper is to highlight the problems of groundwater development in this desert area and the need for careful conservation and efficient use of this vital resource.
