Samenvatting
For a senior- or graduate-level first course in water-resources engineering offered in civil and environmental engineering degree programs. A prerequisite course in fluid mechanics and calculus up to differential equations is assumed.
Water-Resources Engineering provides comprehensive coverage of hydraulics, hydrology, and water-resources planning and management. Presented from first principles, the material is rigorous, relevant to the practice of water resources engineering, and reinforced by detailed presentations of design applications.
