Engineering geology 2019 v.258 pp. 105151
ISSN:
0013-7952
Subject:
dams (hydrology); disasters; earthquakes; floods; friction; landslides; rain; roughness; transportation
Abstract:
... Large-scale landslide dams triggered by earthquakes or rainfall can cause disasters due to inundation upstream and outburst floods downstream after dam failure. Landslide dams formed by rock/debris avalanches are loose in structure and have a lack of stability; thus they are more susceptible to breaking. The morphological and structural features of landslide dams directly depend on the formation p ...

Abstract:
... Dam breach has catastrophic consequences for human lives and economy. In previous studies, empirical models are often, to a limited extent, due to the inadequacy of historical dam breach events. Physical models, which focus on simulating human behavior during floods, are not suitable for fast analysis of a large number of dams due to the complexities of many key parameters. Therefore, this paper p ...

In order to evaluate the recurrence of toxic cyanobacterial blooms and to determine the survival capabilities of the resistance cells through time, a sedimentary core spanning 6700 years was drilled in the eutrophic Lake Aydat. A multiproxy approach (density, magnetic susceptibility, XRF, pollen and non-pollen palynomorph analyses), was used initially to determine the sedimentation model and the l ...

Abstract:
... Nonlinear weirs are regarded as important hydraulic structures for water level adjustment and flow control in channels, rivers and dam reservoirs. One example of non-linear weirs is shaped as curved-zigzag. The crest axis of these weirs is non-linear. At a given width, the crest length is greater than that of the conventional linear weirs. Thus, they achieve a higher flow rate for an identical hyd ...

The geology of SW Turkey comprises Southern (Çine) Submassif of Menderes Metamorphic Massif and the Lycian Nappes. These geological units are unconformably overlain by lignite-bearing Miocene deposits, Upper Miocene–Pliocene conglomerates and Quaternary alluvial deposits. The aim of this s ...

Abstract:
... Siphon turbines are an attractive type of small-scale hydropower turbines because they can be retrofitted into existing structures where there is already a drop in water elevation. A siphon turbine conveys water from an upper reservoir to a lower reservoir through the use of a siphon structure that goes over the top of the dam. A small, neutrally buoyant autonomous sensor package known as a Sensor ...

Abstract:
... In many wetlands the timing and duration of inundation determine ecological characteristics and the provision of ecosystem services; however, wetland conservation decisions often rely on static maps of wetland boundaries that do not capture their dynamic hydrological variability and connectivity. The Amazon River basin contains some of the world's most extensive wetlands, many of which are floodpl ...

Abstract:
... PURPOSE: The sediment yield and erosion rate in an area can be estimated by calculating the volume of sediment retained by check dams. However, results can show unrealistic and imprecise conclusions if the sediment volume is not measured accurately, as tolerable erosion rates are usually below 10 t ha⁻¹ year⁻¹. MATERIALS AND METHODS: Our previous research developed a topographic method (the Sectio ...

Abstract:
... Check dams can modify local channel and sedimentological characteristics through sediment deposition in upstream sedimentary wedges and scour processes downstream of individual check dams. However, research focusing on the channel reaches between subsequent check dams (referred to here as intermediate reaches) is limited. We evaluated channel complexity and its selected dimensions (longitudinal an ...

Abstract:
... Management of water resources is an important issue for better use of water. In this study surface water quality in two stations, located upstream and downstream of Jare Dam in Zard River, was investigated. Water quality was assessed 5 years before and after constructing the dam by using principal component analysis (PCA). To realize the influence of precipitation on water surface quality, standar ...
