availability in a river basin is summarized using indicators of water availability for a) humans
b) environment c) agriculture and d) other uses:
• Water Availability Per Capita (m³ per capita): This indicator shows the amount of
freshwater available for each person in a region, assessing a region's ability to meet
population, economic, and environmental needs. This metric is presented on monthly
and annual timescales, with annual values displayed in horizontal bar plots and
monthly averages in vertical bar plots.
• Water Availability for Further Use (MCM): Highlights the volume of water remaining
for further development after meeting all basin demands, such as natural
evapotranspiration, rainfed agriculture, and domestic and industrial needs. This
measure indicates the potential for future development projects.
• Managed Evapotranspiration Fraction: This fraction shows the part of ET that can be
managed by adjusting land use, cultivation, and water withdrawals to support
effective water conservation strategies.
• Agricultural Evapotranspiration Fraction: Represents the portion of ET from
agriculture, focusing on water consumption in farming and supporting sustainable
water management.
• Irrigated Evapotranspiration Fraction: Reflects the share of agricultural ET from
irrigated agriculture, assessing water use specifically for irrigated crop production.
• Basin Closure (%): Calculates the proportion of water utilized within the basin relative
to total available water. Higher values (closer to 100%) indicate near or complete
usage of water resources in the basin, while lower values indicate additional water
availability.
• Climate Impact: This tab analyzes the potential impact of climate change on rainfall.
Three water drop containers represent different rainfall volume scenarios (8 km3/yr,
7 km3/yr, and 6 km3/yr) compared to the baseline. Four additional area graphs
illustrate trends in ET, rainfall, outflow, and water availability (MCM) for the period
2000-2045 under these scenarios. Assess future water security challenges and inform
adaptation strategies.
