Respected sir,

As a part of the students' project , it is proposed to study the effect of floods
(in coastal regions) on structures ( RC buildings / Pre Engineered Buildings).
 
It is hereby requested to please share your advice(s)/ thoughts on 'how to model flood loads on to the structures'.
.
Thanks & Regards

Just a layman view :-

Floods are generally related to Rivers flowing from upper reaches of Mountains , flowing towards plains and finally merging into sea.
Mountainous reaches , during flood season,, see rise of water levels, with water flowing through narrow gorges , steep bends  ,taking heavy boulders with them downstream. The modelling on structures is in form of rise of water level to HFL plus afflux effects. Structures are also acted upon by heavy boulders hitting piers, abutments,, and protective covering (MS) plus floor protection of barrages is also needed.

In plains flood discharge needs to pass through structures across rivers and modelling is again  in form of water upto HFL plus afflux effects.

Coastal areas are characterised with High tides /Tidal waves of sea plus High wind speeds. According Modelling needs to take care these effects concurrently.

But any sea storms with high winds to be treated separately as wind speeds and wave pressures are very very high.

👆 was lay man view

Hope some modelling / software expert may enlighten, wiseman view .
