Covering the sites with a roof and building protective embankments and dams

rain will drop on the haritage site that can not stop

but as far as flood is concern, from where water is coming to heritage site is big concern,

for stoping/minimizing flood water depend upon site condition

1.divert water to other direction

2.shelter the whole place but it will destroy its look

3. make deep pond or trench around the building to collect outside as well as inside water

so it depends upon site conditions...

These sites should be protected with all care, concern and seriousness of those practices which we have to adopt in areas resided by rural poor. Both Heritage structures and homes of rural poor are very important but highly neglected, and require protection from natural calamities / hazards.

I think the effect is only through floods, but rain is difficult to control

Thank you for your answer .....

in terms of rain protection, on condition your site is not too large you might care to look at the protective measures introduced on the Turkish site of Catal Huyek which has attempted to address these issues.
