Hello dear forum members
Can someone tell me What is the predictor corrector algorithm used by WEAP to solve the mass balance equations in the of soil moisture method ?
Greetings and thanks

WEAP uses a fourth-order Runge-Kutta algorithm ( https://en.wikipedia.org/wiki/Runge%E2%80%93Kutta_methods ) in the predictor corrector loop to solve the mass balance equations. For more information, please read our Water International paper:
