Tools for estimating replenish from land management interventions and check dams
These calculators help quantify the impact of land management interventions on reducing runoff or increased infiltration. Whether you're implementing check dams, changing land use practices, or restoring catchments, these tools provide scientifically-based estimates of additional water infiltration and reductions in runoff.
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:
Each calculator requires climate data in CSV format. You'll need daily precipitation and potential evapotranspiration (PET) records for your project location. The tools will guide you through the upload process and parameter input.
Results include annual average recharge estimates, detailed daily outputs, and visualizations to help you understand the temporal dynamics of your intervention.
