Estimating transmission losses in an arid region--a realistic approach

Transmission loss in ephemeral streams in arid regions is important not only in its obvious effect on downstream flow reduction, but it also forms a part of water balance. Three regression equations were developed for relating transmission loss to channel characteristics for an arid region in north-west India. Two equations utilizing log-transformed data are a better predictor of transmission losses. Although there was some scatter, the transmission loss data are generally consistent with that previously published for other regions. This paper also adds to the database of published data on transmission loss.
