Presentation Transcript

  1. Hydrological networks A.I. Shiklomanov (AARI, UNH), V.S. Vuglinsky (SHI), SAON workshop, 7 July, 2008, St.Petersburg

  2. Hydrological network is the main part of surface water inventory. Hydrological observation data are required for many branches of the national economy, scientific purposes, environmental requests and others. Therefore, the requirements for this information are diverse with time. Main components of hydrological network

  3. Main types of observations on swamps: • Heat balance • Meteorological observations • Water discharge • Water level • Water quality • Ice regime • Peat and soil properties THE SYSTEM OF HYDROLOGICAL OBSERVATIONS IN RUSSIA • Main types of observations on lakes: • Meteorological observations • Water level • Water temperature • Water quality • Waves • Currents • Ice regime characteristics • Ice thickness • Main types of observations on rivers: • Water discharge • Water level • Sediment discharge • Sediment composition • Water temperature • Water quality • Ice regime characteristics • Ice thickness

  4. Dynamic of hydrological network

  5. Shiklomanov et al. (2002) EOS Transactions, AGU, 83(2):13-17. EOS Paper Fig 1 The monitored part of pan-Arctic (red outline) is shown with the density of river discharge gauges in the Regional Roshydromet office (UGMS) responsibility zones in Russia, the provinces in Canada, and Alaska. Values within each administrative unit represent the number of active discharge gauges in 1986 and 1999. The red hatched areas show the loss in monitored area in the 13 years from 1986 to 1999. Shiklomanov A.I., R.B. Lammers, C.J. Vorosmarty (2002) Widespread Decline in Hydrological Monitoring Threatens Pan-Arctic Research, EOS Transactions, American Geophysical Union, v. 83, no. 2 (January 8, 2002), pages 13-17.

  6. Network density of hydrological stations within the territories of Regional Offices of Hydrometeorological Service (ROHS) of Russia on rivers discharging to the Arctic Ocean

  7. Reduction of the hydrological network in different regions of Russia and Canada within the Arctic Ocean drainage area

  8. Gauges and gauge density by permafrost type for the Russian pan-Arctic drainage system

  9. DATA DISSIMINATION AND COLLECTION

  10. Long-term mean annual runoff in the pan-Arctic based on observational data from data available in 1998 (UNESCO/UNH (1996): Global River Discharge Database RivDis v1.0) and from data available in 2006 (UNH R-ArcticNET v4.0 (2005). A Regional, Hydrometeorological Data Network For the pan-Arctic Region. Shown only gauges and watersheds larger 5000 km2).

  11. Time Series End Arctic Runoff Data Base in GRDC 2405 stations 1024 stations with daily data 2193 stations with monthly data

  12. Arctic Runoff Data Base in GRDC Summary statistics of river discharge data kept in the ARDB by country 8 countries earliest record from 1877 (RU) latest record from 2003 (US) average time series length of 35 years (Status: April 2005)

  13. http://www.r-arcticnet.sr.unh.edu/v4.0/index.html

  14. RIMS Real-Time Gauges Real-Time River Discharge Monitoring - Real-Time data - monitoring (first look at hydro cycle) - source of comparison for near-real time models

  15. Russian Data Flow Russian Data Flow to the Arctic and Antarctic Research Institute (AARI) - data collected and passed on to regional Roshydromet offices - FAX, email or teletype to AARI - AARI then does data harmonizing QC data, winter corrections and puts data on web - UNH scoops it and harmonizes with RIMS

  16. Eurasian Arctic River Discharge to the Arctic Ocean and Maximum Sea Ice Extent in the Arctic Ocean R= - 0.7

  17. SAON Hydrology • Hydrological networks to monitor river inflow to the Arctic Ocean • Reference hydroclimatic network to track hydrological response on climate change
