ROAD AND RIVER TRANSPORT IN CENTRAL YAKUTIA,

EAST SIBERIA, RUSSIA

 

DATA PRODUCTION

Climate impact indicators
Global essential climate variables/indicators used

Climate forcing data from the climate data store (CDS) will be used to produce CIIs for historical and future periods representing river ice break-up and freeze-up dates, river ice thickness at the Lena River at Yakutsk as well as ground thawing depths in several dominant landscapes based on model simulations.

Regional/local indicators used and produced

Local meteorological measurements, ground thawing and freezing depths, river ice break-up and freeze-up dates, river ice thickness, ground temperature, water and ice content, landscape, land use, soil and vegetation information will be used to produce the above-mentioned local CIIs.

Global data to regional/local scale

Step 1: Local data collection will include meteorological measurements, ground thawing and freezing depths, river ice break-up and freeze-up dates, river ice thickness, ground temperature, water and ice content, landscape, land use, soil and vegetation cover maps, digital elevation model and user needs

Step 2: Climate model results for historical and future periods will be collected from the CDS.

Step 3: Data analysis will include identification of trends in river ice break-up and freeze-up dates and ice thickness, analysis of ground thawing and freezing, water and ice content in typical landscapes, quality control of climate data and defining future climate scenarios.

Step 4: Local applications of the Hydrograph and HYPE models set-up and estimation of model parameters, simulation and result evaluation, model experiments, model adjustments and future model simulations

Step 5: Model projection, CIIs production for historical and future periods, recommendations for optimal operational period of ice road and ferry at Yakutsk, assessment of road stability due to ground thawing and freezing in typical landscapes will be communicated with the client.
