StateWB was developed to calculate a basin-wide water balance and generate a consumptive use (CU) and losses summary.

Major Features:
  • Uses a Microsoft Access database to calculate an area’s water budget and generates CU and losses reports
  • Relies on a mass balance equation in which inflows minus outflows equal changes in storage
  • Calculates the water budget on a monthly, annual, or average annual time step
Common Uses:
  • Calculate the water budget on a basin-wide scale
