Homotopy based methods in water engineering Exploring the concept of homotopy from topology different kinds of homotopy based methods have been proposed for analytically solving nonlinear differential equations given by approximate series solutions. Homotopy Based Methods in Water Engineering attempts to present the wide applicability of these methods to water engineering problems. It solves all kinds of nonlinear equations namely algebraic transcendental equations ordinary differential equations (ODEs) systems of ODEs partial differential equations (PDEs) system of PDEs and integro differential equations using the homotopy based methods
