The Data of the Observations at the Kolyma Water
Balance Station the Potential of their
Application in Academic and Applied Problems and
the Need for the Resumption of Special Surveys
  • O.M. Semenova
  • State Hydrological Institute Gidrotehproekt Ltd,
    St. Petersburg, Russia
  • L.S. Lebedeva
  • St. Petersburg State University Nansen Centre,
    St.Petersburg, Russia
  • I.N. Beldiman
  • "Khotugu Oruster" (the North Rivers), Yakutsk,
    Russia

Water balance stations of the former USSR
  • 29 water balance stations covered main natural
    zones of USSR but the only one was situated in
    the permafrost environments

Kolyma water balance station (KWBS)
3
Natural conditions
  • Mean air temperature is -11,40?
  • Mean annual precipitation 320 mm
  • Elevation ranges 800-1700 m
  • Variety of landscapes
  • Continuous permafrost with the thickness up to
    400 m
  • Representative for the vast territories of Upper
    Kolyma River Basin

Scheme and instrumentation
  • 31 cryopedometers 25 precipitation gauges 8
    discharge gages 3 experimental plots 2
    meteorological stations 5 transects of snow
    surveys

Brief station history (from the heroic start in
1947 to the pity finish in 1997)
  • 1947 watershed Kontaktovy was chosen as a
    suitable one for organization of observations on
    the basis of extensive field studies of the
    several regions in the Upper Kolyma River basin
  • 1948, May - beginning of the meteorological (2
    sites) and hydrological (3 gages) observations
  • 1949-1960 development of precipitation gages
    network (20 gages). Extension of hydrological
    observation up to 6 gages. Start of measurements
    of evaporation from soil and snow, soil
    thawing/freezing, observation in experimental
    plots.
  • 1957 arrival of modern equipment, staff
    increase, construction of dwellings, partial
    electrification
  • 1968 start of the measurements in the Morozova
    Creek basin, that is
    covered by bare rock entirely

9
Brief station history (from heroic start in 1947
to pity finish in 1997)
  • 1969 renaming from Runoff station to Water
    Balance station that means increasing and
    deepening goals and objectives comprehensive
    experimental studies of land hydrological cycle
  • 1978 snow observations in surrounding avalanche
    catchments snow stratigraphy, temperature and
    mechanical properties at the 4 sites
  • 1980 - ice blister dynamics measurements
  • 1982 observations at the agricultural
    hydrological plots including soil moisture
    measurements
  • By 1989 there are

30 issues of observational material and
archive more than 100 scientific papers and
books dozens of Phd thesis
10
USSR USA collaboration
  • In May, 1977 American scientists Charles
    Slaughter and Michael Bilello from Fairbanks
    visited KWBS. Their impressions

Current state of the KWBS
  • According to information provided by Evgeniy
    Bojarintsev, former director of KWBS, who till
    now is in contact with people from Magadan
  • KWBS in itself have not existed for many years,
    since 1996. There are just three hydrologists
    for the whole Kolyma district and they are in
    administration. Only shortcut meteorological
    observations are conducted. Data repository
    burned in the fire in the station, its copy in
    local administration is lost after the building
    repair...
  • There is a catastrophic situation in the station
    the nearest village was liquidated 10 years ago
    and there is no transport in the station

What is the next? Are we able to continue the
mission of our predecessor? Who will continue
the series of observations?
17
Studies that have been conducted in the KWBS
  • Water balance components, rainfall runoff
    formation (Bojarintsev, Nikolaev , Suschansky,
    Nasybulin, Kuznetsov, Glotov, Glotova)
  • Contribution of ground condensation in the water
    balance (Bojarintsev, Kuznetsov , Bantsekina)
  • Vegetation its connection with hydrological
    regime (Korolev, Pugachev)
  • Thermal and water regime of macrofragmental
    deposits (Bantsekina , Mikhailov )
  • Surface-ground water interaction (Glotov,
    Glotova)
  • Modelling studies (Shmakin, Kuchment, Gelfan,
    Gusev, Nasonova, Semenova, Lebedeva)
  • And others

Prospects of use of the KWBS data
  • Developing and testing of different models
    runoff formation, climatic, environmental and
    vegetation dynamics
  • Climate change studies and assessment of its
    impact on the permafrost state and the
    hydrological regime of rivers for the last 50
    years
  • Experimental studies of specific permafrost
    processes
  • Developing and testing of calculation methods for
    the needs of construction as KWBS is
    representative for vast territories

20
Conclusions
  • The unique observational data collected at the
    KWBS are still not used enough and require
    further researches.
