metadata.value: The article is dedicated to the issues of investigating the impact of off-channel reservoirs on the environment,
  as well as setting seepage losses for working out measures for improvement of the ecological
  situation and land-reclamation condition in the Nakhchivan Autonomous Republic (AR) of Azerbaijan.
  According to the investigations conducted, after putting into operation 16 off-channel reservoirs,
  the hydrogeological conditions and land-reclamation state have changed fundamentally. The ground
  water level has risen from 30–40 m depth to surface, mineralization has increased in 2–10 times at
  the reservoir affected zone, soils were subjected to re-salinization. Seepage losses from off-channel
  reservoirs are one of the signifi cant factors leading to negative features indicating a deterioration of
  the environment. It has been found experimentally that the value of seepage losses under active pressures
  changes from 9 up to 13 per cent per reservoir general capacity. This is connected with the fact,
  that the reservoir’s base consists of permeable rocks, the aquifer lies at 30–40 m depth, dam embankment
  (without impervious barrier) consists of solid loamy soil. That’s why the main part of seepage
  losses come from the reservoir base. Application of anti-seepage measures, for example, artificial mudding
  and catchment of seepage water by the intercepting drainage are needed for seepage prevention.
