Herd suffering with encroaching river given new shelter (8)
I believe the answer is:
rehoused
'given new shelter' is the definition.
'herd suffering with encroaching river' is the wordplay.
'suffering' indicates anagramming the letters.
'with encroaching' means one lot of letters goes inside another (inserted letters encroach into others).
'river' becomes 'Ouse' (Yorkshire river).
'herd' anagrammed gives 'rehd'.
'rehd' placed around 'ouse' is 'REHOUSED'.
(Other definitions for rehoused that I've seen before include "Put in new place" , "put in new shed?" , "given new home" .)
