在干旱和半干旱地区，短河流的水文过程线通常在下游显著减小，除非支流流量增加。这一过程被称为传输损失，其重要性不仅在于其对流量减少的明显影响，而且还在于它是地下水补给到下伏冲积含水层的一个来源。以前的大部分传输损耗研究都是在美国的半干旱地区进行的。在本文中，三个回归方程的相关传输损耗的通道特性在沙特阿拉伯西南部的干旱地区。其中一个方程似乎是可靠的预测与小上游量相关的小损失。另外两个方程是更好的预测大损失与大上游量。传输损耗数据也与一些以前公布的。虽然有一些分散，但数据与以前公布的数据基本一致。本文还对D…
Hydrographs of ephemeral streams in arid and semiarid regions usually decrease significantly in magnitude downstream, unless augmented by tributary flows. This process, termed transmission loss, is important not only in its obvious effect on flow reduction, but also as a source of ground water recharge to underlying alluvial aquifers. Most of the previous work in transmission loss was carried out on the semiarid regions of the United States. In this paper, three regression equations were developed for relating transmission loss to channel characteristics for an arid region in southwest Saudi Arabia. One of the equations seems to be reliable predictor of small losses associated with small upstream volumes. The other two equations were better predictors for large losses associated with large upstream volumes. Transmission loss data were also compared with some previously published. Although there was some scatter, the data is generally consistent with that previously published. This paper also adds to the d...
