General

hymosoffers a number of options to compute catchment rainfall from point rainfall data. The methods differ in the weights given to the point rainfall stations. Following weights are possible:

1. equal station weights (Areal Weights),
2. user specified station weights (Areal Weights),
3. weights according to Thiessen method,

These options are elaborated in the next sections.

There are two ways to enter the codes and weights of the point rainfall stations:

1. the series are selected from a list displayed on the <Screen> and the weights are entered manually (method 2) or are computed, or
2. the series codes and weights are read from the database, prepared at a previous occasion.
