Water is the most important resources for any developmental activities and management of these water resources is of high priority. Water resources evaluation will be done using hydrological parameter as a primary input. SCS -CN methods is a core concept in the subject of hydrology and play a vital role in the evaluation and development of water resources. In the civil Engineering curriculum, the concept of SCS-CN in Hydrology occupies a significant position. 

The present book is intended to serve as a conceptual course in the engineering hydrology at the undergraduate level in the civil engineering discipline. Students specializing in various applications of SCS-CN method such as agricultural engineering etc. will find this book useful. This book also serves as a source of useful information to professional students working in the area of water resources evaluation as a well as development.

The subject concept has been developed in a logical and coherent manner and covers the application part of SCS-CN method. More emphasis is placed on the applicability to field situation. This aspect may be useful to many professional working in the water sector.
