Rainfall triggered landslides are common natural hazards with significant consequences all over the world, including Turkey. Available methods for predicting rainfall-induced slope instability are based on regional statistical data of past slope failures and rainfall records rather than a physically-based model that takes the mechanism of the problem into account. Current study aims to predict rainfall triggered landslides in a laboratory model study, by obtaining rainfall intensity-duration (I-D) thresholds. In a 2-m long laboratory flume setup, in fine sand, slopes are constructed having slope angles of 44 to 60 degrees, and are subjected to rainfall intensities in the range of 4 to 67 mm/hr. Some of the conclusions in this study are: (i) Rainfall intensity duration thresholds that would trigger a landslide (I-D plots) can be obtained in the laboratory. (ii) The shape of the I-D threshold is demonstrated to be mostly a linear relation in log-log plot for the soil used in this study. However, below a certain rainfall intensity landslides are not triggered

Rainfall threshold to trigger landslides in unsaturated soils: A laboratory model study
Ahmadi-adli, Mohammad; Huvaj Sarıhan, Nejan; Toker, Nabi Kartal (2017-09-22)
Rainfall triggered landslides are common natural hazards with significant consequences all over the world. In this study, laboratory model tests are conducted which aims to obtain the rainfall intensity-duration threshold to trigger landslides in a slope composed of unsaturated soil in a flume setup. Sixteen laboratory model tests are conducted to obtain the rainfall intensityduration threshold. Some of the conclusions in this study are: (1) rainfall intensity-duration (I-D) thresholds that would trigger a ...
Shallow landslides triggered by rainfall in nsaturated soils
Ahmadi-Adli, Mohammad; Huvaj Sarıhan, Nejan; Toker, Nabi Kartal; Department of Civil Engineering (2014)
Rainfall triggered landslides are common natural hazards with significant consequences all over the world, including Turkey. Majority of available methods for predicting rainfall-induced slope instability are based on regional statistical data of past slope failures and rainfall records rather than a physically-based model that takes the mechanism of the problem into account. Current study aims to define a numerical model for typical slopes in the region (Northern Turkey), use unsaturated soil properties an...
Numerical simulation of infiltration and evaporation for unsaturated infinite soil slopes
Kenanoğlu, Melih Birhan; Toker, Nabi Kartal; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2017)
Rainfall triggered landslides are common threat in many regions of the world and cause loss of lives and properties. These are shallow failures (typically 3-5 m depths from the ground surface) that occur along a plane parallel to the ground surface where the groundwater level is located at significant depths below, and they are triggered after a heavy rainfall in a short time or after days of lower intensity rainfall (Huvaj et al., 2013). Considering a failure plane oriented parallel to the ground surface, ...
Heyelan Hareketlerinin Fiber Optik Sistemlerle İzlenmesi ve Değerlendirilmesi
Arslan, Arzu; Koçkar, Mustafa Kerem; Akgün, Haluk (null; 2017-11-24)
Landslides are one of the most destructive natural hazards in Turkey. There are several contributing factors that cause landslides such as geological and morphological characteristics, precipitation processes, groundwater level fluctuations, daily temperature changes, snow melt and seismic effects. The purpose of this study is to develop an in-situ monitoring and early warning system by using optical fibers in order to evaluate the effect of contributing factors on the deformation characteristics and to dec...
Flood risk mapping using economic, environmental and sociadimensions
Yeğin, Murat; Kentel Erdoğan, Elçin; Department of Civil Engineering (2015)
Flood is one of the most destructive natural hazards in Turkey. It is unavoidable but its impacts can be minimized by taking necessary precautions. Flood risk mapping is a developing concept and it is used to determine economically, environmentally and socially risky areas. European Council stipulated the member countries to prepare flood hazard maps showing extents of low, medium and high probability flood events. These maps should also be prepared for Turkey during the European Union harmonization process...
