The curve quantity (CN) approach for estimating direct runoff reaction from rainstorms was once built to fill a technological area of interest within the Nineteen Fifties. seeing that then, use of the CN technique has prolonged to different purposes, and person event and research have redefined quite a few gains of the unique know-how. In "Curve quantity Hydrology: country of the Practice", an ASCE/EWRI activity Committee investigates the starting place, improvement, position, software, and present prestige of the CN strategy. issues during this record comprise: an advent to curl quantity hydrology; the curve quantity procedure; findings and advancements; constitution of the fundamental equation; soil moisture modeling; calibration equipment; present utilization perform; and proposals. one of many Committee's techniques is assigning a keeper to function the critical resource for in charge details and updates. An appendix presents strategies to the curve quantity equation. This e-book can be worthy to water and environmental engineers eager about hydrology, specially the research of rainwater runoff difficulties.
