Tools for estimating replenish from land management interventions, check dams, and wastewater treatment systems
These calculators help quantify water stewardship benefits from different types of interventions. Whether you're implementing check dams, changing land use practices, restoring catchments, or treating wastewater, these tools provide scientifically-based estimates of water benefits including additional infiltration, runoff reduction, and water quality improvements.
Evaluate the runoff reduction due to land use and land cover changes using the NRCS Curve Number method.
This calculator uses the Natural Resources Conservation Service (NRCS) Curve Number method to estimate runoff generation before and after land management changes. By comparing pre-project and post-project scenarios, it quantifies the reduction in runoff (which becomes additional infiltration).
Best for:
Calculate the additional annual infiltration from check dams using detailed water balance and Green-Ampt infiltration modelling.
This calculator simulates the daily water balance of a check dam, accounting for inflow from catchment runoff, evaporation from the water surface, and infiltration through the dam bed using the Green-Ampt equation. It tracks storage volume, spillage, and cumulative infiltration over time.
Key processes modelled:
Calculate volumetric water benefits from wastewater treatment projects using the VWBA 2.0 methodology for water quality improvements.
This calculator quantifies the effective volume of water improved through treatment by analyzing water quality improvements across multiple parameters. It calculates a quality factor based on how much each parameter (BOD, COD, TSS, nutrients, DO, etc.) improves toward meeting environmental standards.

Features:
For Curve Number and Check Dam Calculators: Upload climate data in CSV format with daily precipitation and potential evapotranspiration (PET) records for your project location. Results include annual average recharge estimates, detailed daily outputs, and visualizations of temporal dynamics.
For Volume Treated Calculator: Upload water quality data in CSV format or manually select parameters to evaluate. Enter inlet and outlet concentrations for parameters like BOD, COD, TSS, nutrients, and dissolved oxygen. The calculator quantifies volumetric water benefits based on water quality improvements toward environmental standards using VWBA 2.0 methodology.
Each tool guides you through the data upload process and parameter input to generate comprehensive reports of your water stewardship benefits.
