Book Description
Runoff coefficients for the rational runoff formula far seven combinations of cover and cultural practice were derived from single-crop watersheds at Coshocton, Ohio. The rational formula, using the derived coefficients, was evaluated by peak runoff rate frequency curves constructed for fourteen gaged watersheds in Ohio, Wisconsin, Nebraska, and Texas.

Book Description
Abstract: Rational runoff coefficients have been derived for seven combinations of land use and treatment on single-crop agricultural watersheds near Coshocton, Ohio. Runoff coefficient is the ratio of peak runoff rate to rainfall rate. The rational runoff formula has been employed to predict peak runoff rates from twelve experimental mixed-cover watersheds in Ohio, Wisconsin, Nebraska, and Virginia. These peak rates were estimated using the derived runoff coefficients and five different methods of estimating time of concentration. The computed peak runoff rates have been evaluated against runoff records of the watersheds. The SCS-Curve-No. method of estimating time of concentration gave relatively better results.

Book Description
This fully revised edition provides a modern overview of the intersection of hydrology, water quality, and water management at the rural-urban interface. The book explores the ecosystem services available in wetlands, natural channels and ponds/lakes. As in the first edition, Part I examines the hydrologic cycle by providing strategies for quantifying each component: rainfall (with NOAH 14), infiltration, evapotranspiration and runoff. Part II examines field and farm scale water quality with an introduction to erosion prediction and water quality. Part III provides a concise examination of water management on the field and farm scale, emphasizing channel design, field control structures, measurement structures, groundwater processes and irrigation principles. Part IV then concludes the text with a treatment of basin-scale processes. A comprehensive suite of software tools is available for download, consisting of Excel spreadsheets, with some public domain models such as HY-8 culvert design, and software with public domain readers such as Mathematica, Maple and TK solver.

Book Description
The book is designed to serve as a textbook for graduate and undergraduate courses on soil and water conservation engineering for students of agricultural engineering, civil engineering, environmental engineering and related disciplines. The book presents the basics of soil and water erosion, and describes the measures to control erosion, focusing on structures to prevent and control erosion. The chapters dedicated to erosion control structures provide a detailed view of each structural construction, covering the function, design and elements of each type of structure. Some common type of structures covered in the book are terrace, bunds, vegetated waterways, and gully control structures, including spillways. The book also covers wind erosion and control structures to prevent wind erosion. Each chapter includes pedagogical elements such as examples, practice questions, and multiple-choice-type questions to improve understanding and aid in self-study. Besides serving as a textbook university coursework, the book can also serve as a supplementary or primary text for professional development courses for practicing engineers engaged in soil and water conservation or watershed management. The book will also serve as a reference for professionals, environmental consultants, and policy makers engaged in soil and water conservation related fields.
