ology , ▁spo il ▁is ▁the ▁term ▁used ▁for ▁the ▁soil , ▁d irt ▁and ▁rub ble ▁that ▁results ▁from ▁an ▁exc av ation , ▁and ▁disc arded ▁off ▁site ▁on ▁spo il ▁he aps . ▁These ▁he aps ▁are ▁commonly ▁accessed ▁by ▁bar row ▁runs . ▁ ▁Spo il ▁management ▁ ▁Effect ive ▁management ▁of ▁spo il ▁is ▁necessary ▁because ▁its ▁volume ▁is ▁in ▁general ▁three ▁times ▁that ▁which ▁it ▁was ▁before ▁exc av ation . ▁Best ▁practice ▁involves ▁removing ▁the ▁spo il ▁away ▁from ▁the ▁exc av ation ▁site ▁by ▁mechanical ▁earth ▁moving ▁equipment , ▁or ▁the ▁creation ▁of ▁bar row ▁run ▁fed ▁spo il ▁he aps . ▁In ▁the ▁bar row ▁run ▁method , ▁a ▁r amp ▁is ▁built ▁using ▁spo il ▁transport ed ▁in ▁bar rows ▁along ▁the ▁bar row ▁runs . ▁The ▁spo il ▁heap ▁is ▁progress ively ▁en larg ed ▁by ▁t ipping ▁off ▁the ▁vertical ▁end ▁face ▁of ▁the ▁bar row - run . ▁This ▁method ▁is ▁efficient ▁in ▁storing ▁the ▁maximum ▁amount ▁of ▁spo il ▁in ▁the ▁minimum ▁area , ▁where ▁there ▁is ▁no ▁mechan ised ▁means ▁of ▁removing ▁spo il ▁a ▁long ▁distance ▁from ▁the ▁site . ▁ ▁References ▁▁ ▁The ▁Mo L AS ▁arch ae ological ▁site ▁manual ▁Mo L AS , ▁London ▁ 1 9 9 4 . ▁. ▁R b ▁ 1 2 8 pp . ▁bl / wh ▁ ▁Category : Methods ▁in ▁arch ae ology <0x0A> </s> ▁Ins pect or ▁Gan esh ▁V . ▁Gh ote ▁( pr on
