✦ Synopsis

In this paper we derive Lagrange's equations for a rigid body rotating about its centre of gravity. We base our calculations on the balance law of angular momentum and refrain from the use of the customary and deficient model in which a rigid body is regarded as a limiting case of a rigid system of mass points. After some kinematical preliminaries we proceed in two ways. First we apply coordinates to achieve our goal, and in a second approach we do without them. The latter analysis is seen to be very simple.

The basic aim of this paper is to formulate rigorous conservation equations for mass, momentum, energy and entropy for a watershed organized around the channel network. The approach adopted is based on the subdivision of the whole watershed into smaller discrete units, called representative elementa
