"For the past five years, the writer has been engaged either directly or indirectly in the investigation of water supplies. Studies and observations made in Texas, Oklahoma, Colorado, and New Mexico, have brought to his attention the importance of geology to hydrology. This is especially true in reference to the relation between rainfall and run-off. In all texts and other publications relating to hydrology, the importance of geology to the subject is hardly more than mentioned. In the absence of actual stream flow records, many engineers resort to either the "direct comparative method", or the "rainfall percentage method", in estimating the average annual yield of drainage basins ... The writer is of the opinion that a combination of the two above mentioned methods is the most practical method for the average engineer to employ when estimating yields of basins in the absence of actual stream flow records. Furthermore, the writer believes that a careful comparison of the topographic, climatological, as well as other physical features, is not sufficient for comparative purposes, unless, a careful study of the geology of the areas is also included"--Introduction, pages 4-5.
