Technical Abstract: A book on mathematical models of small watershed hydrology and applications was recently published by Vijay P. Singh and Donald K. Frevert. This review article summarizes the content of this book and provides an opinion on the book's appeal for students and practitioners engaged in hydrologic modeling and applications of such models. The book is organized into five sections with a total of 23 chapters, covering a range of model types. The book is an excellent reference for students engaged in model development and application. It showcases how basic classroom hydrologic concepts are integrated into powerful application tools of watershed hydrology. A practitioner will also find this book useful as it provides theoretical foundations and model conceptualization for a wide range of models including distributed, parametric, real-time forecasting and environmental models. On the down side, many chapters lack a discussion of the strengths, weaknesses, capabilities and limitations of the models. A discussion of these attributes would have provided a fuller appreciation of the value of a model and helped in the assessment of model suitability and implementation potential for practical applications.
