Continuous rainfall patterns are currently simulated by approximating them by stair‐stepped (piece‐wise) patterns. The effects of this approximation on infiltration and runoff processes are not well known. A new technique for simulating smooth‐variable intensity rainfall patterns is presented. This technique is based on the fundamental principles of a moving water head in a container. The proposed technique is general and capable of simulating any rainfall pattern. However, as the rainfall pattern gets more complicated, the equipment required for simulation becomes more involved. The proposed technique has been tested experimentally. A close agreement was found between the theoretical and experimental simulations. It is concluded that the proposed technique might be very useful in studying the infiltration and runoff processes under variable intensity rainfall, especially for simple convex patterns.
