Dam Failure Concepts and Modeling
This lesson provides an in-depth case study to illustrate principles of dam failure modeling and examines some of the critical data inputs and outputs. Output is provided from the U.S. Army Corps of Engineers HEC-RAS model for simulated failures of a large dam. Several simulations are presented that show the impact from varying the size of the breach and the time it takes the breach to fully develop. The lesson also summarizes several infamous large dam failures from around the world and the impacts from other factors are such as reservoir shape and size, the age of the dam, and the material u ...

Overview of Watershed and Channel Sedimentation
This lesson provides an overview of the primary influences of watershed and channel sedimentation. In a short narrated portion of the lesson, we explore a section of the Rio Grande watershed and channel in New Mexico using Google Earth imagery, river profiles, and graphic animations. We highlight features of the upland catchments, the river channel, and the Elephant Butte Reservoir. We then demonstrate how environmental factors (climate, geography, land use changes, reservoirs) impact the supply and movement of sediments for the Rio Grande and other rivers. The focus is on the three primary pr ...

We highlight features of the upland catchments, the river channel, and the Elephant Butte Reservoir. We then demonstrate how environmental factors (climate, geography, land use changes, reservoirs) impact the supply and movement of sediments for the Rio Grande and other rivers. The focus is on the three primary processes in sedimentation: generation, transport, and deposition. The lesson then addresses natural climate and weather influences along with some observed and projected trends associated with climate change.

Bivariate analysis and synthesis of flood events for the design of hydraulic structures – a case study for Argentina
A bibliographic review of the state of art of flood estimation techniques shows the importance of studying floods as multivariate events. The aim of this work is to discuss whether a multivariate analysis is necessary for designing dams or for assessing the adequacy of spillways belonging to existing dams. A multivariate approach offers a range of possible events associated to a joint return period, which can be used in a design stage. The multivariate criterion includes information related with the dependence structure linking the flood variables. This dependence is involved in the generation ...

A bibliographic review of the state of art of flood estimation techniques shows the importance of studying floods as multivariate events. The aim of this work is to discuss whether a multivariate analysis is necessary for designing dams or for assessing the adequacy of spillways belonging to existing dams. A multivariate approach offers a range of possible events associated to a joint return period, which can be used in a design stage. The multivariate criterion includes information related with the dependence structure linking the flood variables. This dependence is involved in the generation of random flood samples, which are used for risk assessment of existing dams.

Operational hydrology report (OHR), 26. Methods of measurement and estimation of discharges at hydraulic structures
A review of methods for the measurement and estimation of discharges at hydraulic structures and pressure conduits with the aim of using such facilities, where they already exist, as an alternative to the construction of discharge measurement stations. Focus is on methods of flow estimation at structures commonly installed in reservoirs, dams and canals as well as standard methods for the measurement of open-channel and pipe flow. Mention is also made of the use of pumping stations and navigation locks.

IUGG Yearbook
The IUGG Yearbook is a reference document of IUGG members, administrative officers, and Association and Union Commission officers that is updated annually and distributed free of charge. Each issue endeavors to update the contact information for hundreds of persons who are actively participating in IUGG scientific activities. Information is complied throughout the year until early December. The print-ready copy is sent to the publisher in late December, and the Yearbooks are distributed as soon as possible thereafter.
