Taesam Lee, Ph.D., is an associate professor in the Department of Civil Engineering at Gyeongsang National University. He got a Ph. D. degree from Colorado State University with stochastic simulation of streamflow. He specializes in surface-water hydrology, meteorology, and climatic changes in hydrological extremes publishing more than 40 technical papers.Vijay Singh, Ph.D., D.Sc., D. Eng. (Hon.), Ph.D. (Hon..), P.E., P.H., Hon. D. WRE is a Distinguished Professor, a Regents Professor, and Caroline & William N. Lehrer Distinguished Chair in Water Engineering in the Department of Biological and Agricultural Engineering and Zachry Department of Civil Engineering at Texas A & M University. He specializes in surface-water hydrology, groundwater hydrology, hydraulics, irrigation engineering, and environmental and water resources engineering. Professor Singh has published extensively and has received more than 90 national and international awards. .

Statistical downscaling helps to obtain the required resolutions of hydrological variables. The book of Taesam Lee and Vijay P. Singh fills an important gap as to my knowledge no dedicated treatises on this particular topic are available so far.I find this book especially helpful for hydrological modelers who want to examine how to handle the scaling of hydrological events such as extreme rainfall, floods, and droughts at the local, watershed level. In addition, honours-level undergraduates with a decent grounding in environmental science should find the material accessible, and modern in its coverage of topics such as how to properly correct for significant biases with the observational data normally found in current Global Climate Models (GCMs). Especially the numerous tables with example data help to apply the methods to simple exercises. However, for easier access to the practical examples the tables should have been made available online. With the diverse applications of statistical downscaling methods the readers´ awareness of these scaling techniques on environmental simulation results is raised. It will be useful to researchers in hydrology, hydroclimatology, agricultural and environmental sciences, and watershed management. — Vadose Zone Journal, January 2019
