Online Engineering Tools
Practical calculators and utilities built for engineers, students, and professionals.
SPI Calculator: Standardized Precipitation Index from Monthly Rainfall
Paste a monthly rainfall series and get the SPI at 1 to 24 months using the standard McKee et al. (1993) gamma method, the drought category of every month, a list of drought events with duration and severity, and a multi-scale heatmap that shows how short dry spells grow into long droughts.
Flood Frequency Analysis Calculator (Gumbel, Log-Pearson III, Normal & Log-normal)
Paste annual maximum floods and get the 2- to 1000-year design floods from four distributions side by side, Gumbel confidence limits, a Gumbel probability plot with your data, a goodness-of-fit ranking, the return period of any given flood, and the full step-by-step
SCS Curve Number Runoff Calculator
Estimate direct runoff depth and volume from a storm with the SCS-CN (NRCS curve number) method. Build a composite curve number from the complete TR-55 tables,
Mann-Kendall Trend Test Calculator with Sen's Slope Estimator
Paste a time series and get the Mann-Kendall S statistic, variance (with tie correction), Z, p-value, Kendall's τ and Sen's slope with its confidence interval. Includes the Hamed-Rao and trend-free pre-whitening corrections for autocorrelated data,
Asphalt Calculator: Tonnage, Cost & Quantity
