We use the geometric notion of a differential system describing surfaces of a constant negative curvature and describe a family of pseudospherical
surfaces for the KdV-Burgers-Kuramoto and nonlinear Schrödinger equations with constant Gaussian curvature . Travelling wave solutions for the above equations are obtained by using a sech-tanh method and Wu's elimination method.
