氘组成的深度剖面，表示为三角洲值，已被用来使点估计蒸发从通常“干”湖弗罗姆，盐湖在北方南澳的地板。来自五个地点的数值在90 ~ 230 mm/年之间变化，用于获得170 mm/年的湖泊平均蒸发率的相对粗略的近似值。假设这代表区域地下水系统的排水量，则流入湖泊的地下水流量计算为0.55 × 108 m3/年。两种可能的模型，描述地下水流入湖泊进行了讨论。
Depth profiles of deuterium composition, expressed as delta-values, have been used to make point estimates of evaporation from the floor of the normally “dry” Lake Frome, a salt lake in northern South Australia. Values from five sites, varying between 90 and 230 mm yr.−1, have been used to obtain a relatively crude approximation for mean evaporation rate from the lake of 170 mm yr.−1. Under the assumption that this represents discharge of water from the regional groundwater system, the groundwater inflow into the lake is calculated as ∼ 5 × 108m3yr.−1. Two possible models which describe groundwater inflow into the lake are discussed.
