a$.$ A mine dump in a small mining town is located next $($and along$)$ the main access road into town. The dump is $300m$ long and divided into $5$ sections of varying heights: $8m,12m,20m$ and $25m.$ The internal friction angle of the dump material is $30$ degrees, density $2\mathrm{.}5\frac{g}{c}m3$ and the internal cohesive strength of $5$kpa. Average angle of repose of the dump material is $60$ degrees.The town experiences heavy rainfall throughout the year.

Investigate the safety of motorists driving along this route throughout the year and provide recommendations where necessary.
