<p>The paper focuses on the application of gabion structures in river control and particularly on transversal gabion weirs and spillways in flood storage projects. Storage has the general effect of attenuating the flood hydrograph, reducing its peak flow rate ...

<p>The original design of a dam may be reevaluated for a number of reasons, including the occurence of an incident or unusual load, the availability of new information, the refinement of certain design requirements or guidelines, the adoption of risk-based ...

<p>This study was carried out in selected districts of Mashonaland, East and Central provinces of Zimbabwe in 2011 to determine the environmental impacts of earth dam failures and spillway malfunctions with regards to soil erosion. A total of 14 earth dams ...

<p>Scour of rock is a complex process and can be very problematic for dams when excessive scour threatens dam stability. Removal of individual rock blocks is one of the principal mechanisms by which scour can occur, particularly in unlined spillways and on ...

<p>This ongoing research will help answer the questions that continue to arise as Reclamation is faced with detailed analysis and modifications of spillways and other earth-retaining structures subjected to significant seismic loading. The objective of this ...

New Zealand is located in the area of active seismicity on the boundary between the Australian and Pacific plates. Most dams in New Zealand are in the close proximity to active faults and some dams have been built across active faults. The paper describes ...

<p>Up to now the investigations developed about the hydraulics of stepped spillways in RCC dams, are focused in analyzing the flow over an uncontrolled spillway. There isn&rsquo;t much information about the behavior of gated stepped spillways. For this reason ...

The Department of Environmental Conservation receives many requests for detailed information about designs for dams requiring a permit under Article 15, Section 0503 of the Environmental Conservation law. This brochure has been developed by the department ...

<p>Little information is provided on the energy dissipation that occurs in stepped spillways with slopes less than or equal to 22&deg; (slopes commonly found among NRCS constructed spillways). Renwick Dam in North Dakota falls in this unique class of planned ...
