Rainfall triggered landslides in unsaturated soils a numerical sensitivity analysis for rainfall threshold Ahmadiadli, Mohammad; Huvaj Sarıhan, Nejan; Toker, Nabi Kartal (2012-04-27) Catastrophic precipitation-induced landslides have frequently hit villages, towns and roads in Black Sea Region in northern Turkey, causing extensive damage and many fatalities. Due to global climatic changes, the intensity and frequency of extreme rainfall events are expected to increase. In addition, due to limited available land on level ground, urbanization continue to increase on sloping ground which increases the exposure and elements at risk. Most available methods for predicting rainfall-induced slo...
Rainfall-triggered landslides in an unsaturated soil: a laboratory flume study Ahmadi-Adli, Mohammad; Huvaj Sarıhan, Nejan; Toker, Nabi Kartal (2017-11-01) Extreme and/or prolonged rainfall events frequently cause landslides in many parts of the world. In this study, infiltration of rainfall into an unsaturated soil slope and triggering of landslides is studied through laboratory model (flume) tests, with the goal of obtaining the triggering rainfall intensity-duration (I-D) threshold. Flume tests with fine sand at two different relative densities (34 and 48%) and at slope angle of 56.5 degrees are prepared, and rainfall (intensity in the range of 18 to 64 mm/...
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 ...
Drought analysis of Konya Closed Basin with the use of TMPA satellite-based precipitation data Yılmaz, Meriç (2017-01-01) Investigation of drought that has heavy sociological and economical costs to countries is very important to alleviate its adverse impacts and to take the necessary precautions. Konya Closed Basin, which has critical role in terms of agricultural yield for our country, is one of the regions where the impact of the drought is felt the most due to its semi-arid climate. For this reason, in this study, severity, duration, and impact area of drought is analyzed over Konya Closed Basin between 1998 and 2015. In t...
