Q$2$ Figure $1$ shows a rectangular rural catchment $(100km4km)$ whose catchment outlet is at $C($i$.$e one corner of the catchment$).$ Two raingauges are located outside the catchment at A and $B.$ The location of the raingauges with respect to the catchment is also shown in Fig. $1.$ During a storm, the raingauges A and $B$ recorded $60mm$ and $40mm$ respectively over a period of $24$ hours.

$(2)$ Determise the catchment rainfall for this storm using the Thiessen Polygon Method.

$($b$)$ Datarmine the temporal rainfall depth distribution of this storm for the o catchment, asuming the temporal distribution $(\%)$ given below for a

$24.$kr storm in terms of $4kr$ time intervals. Tabolate your revilts.
