45“…The sustainability of large dams has been questioned on several grounds. One aspect that has been less explored is that the development of dams and reservoirs often enables agricultural expansion and urban growth, which in turn increase water consumption. …”

49“…This book aims to inform policy-makers, engineers and earth scientists about the current and emerging role of geophysics in addressing environmental processes, assessments, and policy directions related to new and existing dams and levees. Until now geophysics has concentrated on characterization and remediation of dams and levees, but now the field is changing our understanding on the influence of natural processes (e.g., floods, dissolution) and human activities in the design, and management of these structures. …”

50“…We argue that another important, yet understudied and unquantified, contributor to tribal land loss is through the construction of dams. By restricting water flow in rivers or lakes, dams submerge land under reservoirs and disrupt aquatic and terrestrial ecosystems. …”

59“…The flood propagation at a confluence of channels exhibits a unique routing pattern, while there are few studies on the routing of dam-break flow in confluent channels. In this study, we conducted physical experiments and a numerical simulation to investigate the influence of different confluence angles on the routing of a dam-break flood. …”

60“…To demonstrate that the thermal destabilization by hydropower dams can be managed while maximizing energy production, we modelled thermal change in downstream waters as a function of decision variables for hydropower operation (reservoir level, powered/spillway release, storage), forecast reservoir inflow and air temperature for a dam site with in situ thermal measurements. …”
