Population density in the Malaprabha (K4) sub-basin area. The dataset, calculated as number of people per hectare, is derived from the WorldPop datasets (https://www.worldpop.org/)

Total Flow (calculated for the Malaprabha (K4) sub-basin area. The total flow (tf) is the sum of surface runoff (sro) and the base flow (bf). More information can be found on the IHE Delft Water Accounting report of Karnataka.

Precipitation calculated in the Ghataprabha (K3) sub-basin area, derived from the Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) (ftp://ftp.chg.ucsb.edu/pub/org/chg/products/CHIRPS-2.0/). Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) is a 35+ year quasi-global rainfall data set. Spanning 50°S-50°N (and all longitudes) and ranging from 1981 to near-present, CHIRPS incorporates in-house climatology, CHPclim, 0.05° resolution satellite imagery, and in-situ station data to create gridded rainfall time series for trend analysis and seasonal drought monitoring.

Population density in the Middle Krishna (K2) sub-basin area. The dataset, calculated as number of people per hectare, is derived from the WorldPop datasets (https://www.worldpop.org/)

Reference Evapotranspiration calculated for the Malaprabha (K4) sub-basin area. The reference evapotranspiration (et_ref) is defined as the evapotranspiration from a hypothetical reference crop and it simulates the behaviour of a well-watered grass surface. The value of each pixel represents the total monthly reference evapotranspiration for that specific month. Reference evapotranspiration is derived using the Penman-Monteith equation. The following data is used to calculate RET: daily incoming solar radiation and weather data (temperature, humidity, wind speed).

Total flow (calculated for the Middle Krishna (K2) sub-basin area. The total flow (tf) is the sum of surface runoff (sro) and the base flow (bf). More information can be found on the IHE Delft Water Accounting report of Karnataka.

Number of rainy days calculated in the Middle Krishna sub-basin area. For every pixel, the number of rainy days in a month is reported. This dataset is created by using daily rainfall data from the Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS).

Leaf Area Index calculated in the Ghataprabha (K3) sub-basin area. The Leaf Area Index or LAI is a dimensionless quantity which is used to characterize plant canopies. It is defined as the one-sided green leaf area per unit ground area in broad leaf canopies and as one-half the total needle surface area per unit ground area in coniferous canopies. In Water Accounting is used to compute Interception. This data was collected from NASA's Land Processes Distributed Active Archive Center (LP DAAC).

Base flow calculated for the Malaprabha (K4) sub-basin area. Base flow (bf) or slow flow is the component of the total flow that is due to groudwater discharge. It mainly occurs during dry months. The calculation of base flow is based on a pixel-based soil water balance model. More information are available in the IHE Delft water accounting report of Karnataka.

Percolation calculated for the Malaprabha (K4) sub-basin area. The Percolation (perco) is the amount of soil moisture in the root zone that leaks deeper contributing to groundwater recharge. The calculation of Percolation is based on a pixel-based soil moisture balance model. More information can be found on the IHE Delft Water Accounting report of Karnataka.
