Environmental Health Perspectives, 1997 Once a sign of modernization and growth, dams are often seen today as symbols of environmental and social devastation. Over 800,000 dams have been built worldwide to provide drinking water, flood control, hydropower, irrigation, navigation, and water storage.

Comparison Study of Two Methods Used to Estimate Surface Runoff Hydrograph for Small Basins
Journal of Engineering and Sustainable Development, 2014 In this study Rainstorm hydrograph peak discharge and unit-hydrograph peak discharge in small basins were calculated and evaluated using various methods for peak discharge assessment applying 6-hour storm rainfall duration. Rainfall-runoff models: HEC-

Safety Assessment of Concrete Gravity Dams: Hydromechanical Coupling and Fracture Propagation
GeosciencesFor the safety assessment of concrete dam–foundation systems, this study used an explicit time-stepping small-displacement algorithm, which simulates the hydromechanical interaction and considers the discrete representation of the foundation ...

Assessment of Contact Laws Accounting for Softening in 3D Rigid Concrete Particle Models
BuildingsTo obtain predictions closer to concrete behaviour, it is necessary to employ a particle model (PM) that considers contact softening. A bilinear softening contact model (BL) has been adopted in PM studies.
