Thiessen Polygon Method for Average Rainfall:
Rain gauges measure rainfall at points, but floods, water budgets and hydrological models need the average over an area. This guide explains the three classical methods, lets you drag gauges on a live catchment and watch the Thiessen polygons
Rational Method (Q = CiA): Formula, Runoff Coefficient Tablle
The rational method is the most widely used way to size storm drains, culverts and gutters for small catchments. This guide covers the formula in SI and US units, where each term comes from, how to pick C, how to compute the time of concentration and
Hydrograph: Complete Theory, Unit Hydrograph & Derivation
A hydrograph is a graphical representation of the variation of discharge (or stage) of a stream at a given gauging station plotted against time. In hydrology, it is the single most important tool for understanding and quantifying the rainfall-runoff response of a catchment. Every flood estimate, reservoir design, culvert sizing, and floodplain mapping exercise depends either directly on a measured hydrograph or on a model capable of reproducing one.
3-Point Bending Test Equations
The 3-point bending test (also written as three-point bend test or flexure test) is a standardised mechanical test that measures the flexural properties of a material by loading a beam specimen at its midpoint while it rests on two supports
