DATABASE OF THE CHIRCHIK-AKHANGARAN-KELES
SUB-BASIN’S INTEGRATED MODEL

The database on water resources has been designed to store initial information necessary for hydrological model calculations.

The database contains the following information objects:

Point objects

• Gauging stations
• River and canal escapes
• Escapes for industrial and municipal wastewater
• Head water intakes at canals
• Hydroschemes
• Hydro power plants
• Thermal power plants
• Reservoirs

Linear objects

• Rivers
• Canals
• Collectors

Areal objects

• Planning zones (districts)
• Flow formation zones (sub-basins)

The key parameters

1. Hydrological and water-management information, energy sector

• River runoff and its salinity,
• Discharge from canals into rivers and idle discharge,
• Discharge into rivers and reservoirs from collectors (from irrigated land, with refer-ence to PZ and irrigation systems), household and domestic waste discharge (cities, villages), industrial wastes, salinity of waste discharges,
• Transfer flow at PZ boundaries – main canals and collectors (points of water trans-fer),
• Withdrawals from rivers and reservoirs,
• Reservoir operation regimes – water level, water volume and salinity at the begin-ning and the end of month, inflow, withdrawal and releases from reservoirs,
• Groundwater – usable groundwater resources, groundwater inflow and outflow, dis-charge, filtration losses in rivers and reservoirs, abstraction from groundwater sources per user,
• Water distribution:
  • Uzbekistan – total, including from: Chirchik, Akhangaran, small rivers (Ugam, Ak-tash, Aksakata),
  • Kyrgyzstan (Chatkal River),
  • Kazakhstan (VDK, etc.),
  • Uzbekistan’s irrigation systems (Tashkent main canal, “Bozsu” system, “Parkent-Karasu” system, “Akhangaran-Dalverzin” system) – irrigated farming, agricultural water supply, fishery,
  • Urban and industrial centers (Tashkent, Chirchik, Yangiyul, Almalyk, Angren) – household-drinking needs, industry (Chirchik chemical plant, Almalyk industrial system, Angren coal open-pit mine),
  • Internal use (with reference to irrigation systems): groundwater, CDW.
• HEPS parameters: gross and net storage volume of reservoirs, highest controlled water surface, maximum water surface, water head in HEPS under the highest con-trolled water surface and dead-storage level, HEPS capacity, installed power.
• Limitations:
  • Recreation demand – minimum level of Charvak reservoir drawdown (summer, winter),
  • Limitations for Charvak reservoir regarding seismicity – filling below the set level,
  • Limitations for Charvak reservoir regarding non-admission of dust storms – draw-ing off not below the set level,
  • Environmental demand for runoff: minimum flow along Chirchik river downstream of Charvak reservoir.
• Heat-power engineering – operation parameters and requirements of State rayon power stations.

2. Land resources and their use

• Land fund (arable land, perennial plants, fallow land, hayfields, pastures, agricultural land, other lands),
• Irrigated areas – total, including sources: river intake (transboundary flow, main riv-ers), sai, springs, wells, collector-drainage water (CDW),
• Area under drainage, drainage modulus,
• Distribution of areas per soil salinity, groundwater level and salinity, index of soil quality,
• Cropped area, including non-irrigated, cropping patterns and crop yields,
• Agricultural production in irrigated and dry lands (seeding dates, cultivation dates, gross harvest).

3. Ecology

• Water quality:
  • Physical and chemical characteristics,
  • Salinity and main ions,
  • Biogenic elements,
  • Organic matter,
  • Heavy metals.
• Parameters of ecological hydroecosystem assessment,
• Parameters of ecological landscape (natural, agricultural) assessment,
• Parameters of anthropogenic load on ecosystems and evaluation of load conse-quences (irrigated agriculture, livestock, fishery, industrial and municipal enterprises, etc.).

4. Socio-economic parameters

• Operational costs and net cost:
  • Costs of crop production per variety: total; machinery; labor costs; seeds; fertil-izer; fuel; other; administration; depreciation charges,
• Water and agricultural output prices
  • Purchasing and market prices of agricultural output,
• Productivity:
  • Irrigation water per irrigation system,
  • Industrial water use (per plant),
  • Household and drinking water use,
• Demographic and macro-economic indicators
  • Population trends, including urban, working population, occupied in economy and agriculture,
  • Industrial production volume,
  • Agricultural production volume,
  • Investments,
  • GDP, industrial and agricultural shares,
  • Population income,
• Water use norms – for crops, household and drinking water supply,
• Production volumes:
  • agriculture,
  • fishery,
  • livestock,
  • output of livestock farming,
  • allied industries,
  • power sector, including hydropower,
  • industry,
• Recreation and tourism

5. Climate data

• Temperature, precipitation, evaporation, relative humidity (per weather station).
