Modelling Rivers


Rivers are natural water courses. They have vital contributions to the social and economical welfare of societies living along their course. They provide continuous, usually dependable, flow and supply of water. Accordingly, centralised civilisation began emerging independently along number of river valleys; e.g. the Nile, Tigris and Euphrates, the Indus and the Yellow Rivers. Since then, mankind has been in continuous struggle to understand and live in harmony with this gift/force of nature. Modelling rivers is the modern way to understand their behaviour and is an essential tool to tackle several river problems.

How to use matlab tool vs_let() get the Ux and Uy, not velocity in M and N

I want to fastly get the velocity direction though Matlab. So I use function vs_let() to get the U and V, then arctan(U,V) to get the direction.

U=vs_let(Nfs,'his-series',{0},'ZCURU',{0 0});
V=vs_let(Nfs,'his-series',{0},'ZCURV',{0 0});

Since I hope I could fast process this data, I prefer not to use Quickplot. Howver, I could only get the velocity in M and N direction, rather than velocity in X and Y direction. How could I get the latter ones?

Anybody could give some advice?
