A landslide is a natural disaster that occurs when a mass of rock, earth, or debris moves down a slope. Landslides can be caused by a variety of factors, including earthquakes, heavy rainfall, and human activity. In 2013, the Indian state of Uttarakhand was hit by a series of landslides that caused widespread damage and loss of life. This essay will provide a case study of the Uttarakhand landslides, including their causes, impacts, and efforts to prevent future landslides.
One of the main causes of the Uttarakhand landslides was heavy rainfall. In June 2013, the region experienced unusually heavy monsoon rains, which caused the soil on steep slopes to become saturated and unstable. This, combined with the fact that many of the slopes in the region are steep and prone to landslides, made the region particularly vulnerable to landslides.
The landslides in Uttarakhand had severe impacts on the local population and the environment. The landslides caused widespread damage to infrastructure, including roads, bridges, and buildings. Many people were left homeless and without access to basic necessities such as food and water. In addition, the landslides caused significant loss of life, with over 5,000 people being killed or reported missing. The landslides also caused environmental damage, including soil erosion and the destruction of forests.
In the aftermath of the landslides, the government of Uttarakhand and other organizations took steps to prevent future landslides in the region. These efforts included the construction of retaining walls and the stabilization of slopes, as well as the implementation of better land use and development practices. In addition, the government implemented measures to improve the preparedness and response to landslides, such as the establishment of early warning systems and the development of evacuation plans.
Overall, the Uttarakhand landslides serve as a reminder of the devastating impacts that natural disasters can have on communities and the importance of taking steps to prevent and mitigate such disasters. While it is not always possible to completely prevent landslides, by implementing appropriate measures and taking a proactive approach, it is possible to reduce the risk of landslides and their impacts.
Uttarakhand Landslide Case Study: Monitoring of Narendra Nagar Landslide
The analysis has been done using Mohr-Coulomb constitutive model. Elevation ranges from 380m to 2180m above the standard sea level. The Uttarakhand landslide case study suggests that fragile geology, heavy downpours and critical slopes are significant factors responsible for Uttarakhand landslides. Settlement calculation is an important part in the design of shallow foundations resting on granular soils. Uttarakhand has the highest number of unstable zones in northern India. Rise of ground water level is believed to increase the settlement significantly and had been a topic of research for many years.
A total of 84 square km area was mapped by the scientists and experts for research on this. Some hazard adjustments that could be conducted by the local government would be to update the drainage system so that it can improve the flow of rain water during storms. Presently, statistical approach is the most popular for landslide susceptibility assessment. The Cedar River is an important part of the city but it also puts the city at high risk for flooding creating another devastating disaster to the people in Cedar Rapids. The development of these applications is still ongoing, not only on the evaluation of the performance, but also on expanding the applications of these advanced and continuously developing geo-engineering materials.
Landslides and the road network in Uttarakhand, India
The temperature in this region varies from 1. Environmental Earth Sciences, 2010. It is known as subjective approach to produce reliable results. Large pieces of mountains are cut and removed using heavy machinery coupled with explosives to create wider roads. In this report, it will document infrastructure affects, stormwater management, Climate Whiplash and thoughts from the geologist on the desert-flood relationship. Besides, CBRI Roorkee has been asked to suggest safe building designs keeping in mind land subsidence in Joshimath. Examples of natural disasters are Earthquakes Haiti 2010 , Tornadoes, Tsunami, Hurricanes, Wild Fires, Winter Storms, Heat waves, Mudslides and Floods.
Uttarakhand govt orders geological study of 'sinking Joshimath'
Landslide is a complex phenomenon thus researchers all are trying to understand its mechanism in order to mitigate their harmful impaction. Higher AUC values indicate better performance of the FR model. . Often, potential landslide areas are perpetual danger zones as they create havoc everywhere and are highly capable of destroying our place of shelter. Soeters, Landslide hazard and risk zonation-why is it still so difficult. These analyses contribute not only to the evaluation of the dynamic response of soil reinforced structures, but also to the identification of the developed failure modes.

So the indiscriminate road widening without paying attention to geology, lithology, slope etc are invitation to landslides. Geological composition of some well known areas of Bhataghat, George Everest, Kempty fall, Khattapani, Library road, Galogidhar and Hathipaon in and around the hill town has 'Krol' limestone as a major component, which is considered to be fragile. Farmers are forced to move farther and farther out into the delta, triggering them to face the perilous monsoon season, which is from June to October. DEHRADUN: A recent Landslide Susceptibility Mapping LSM study carried out by Wadia Institute of Himalayan Geology, Dehradun has revealed that Mussoorie is 'highly susceptible' to landslides. It can be observed that the AUC of success-rate curve is 0. Environmental Earth Sciences, 2011.
Lee, Regional landslide susceptibility analysis using back-propagation neural network model at Cameron Highland, Malaysia. Considering the value of the preparatory behavior, governments, local, national and international institutions and non-government organizations made some efforts in promoting disaster preparedness. How many landslides occur in Uttarakhand? Terrain surface of the study area is very steep with slope angles ranging from 0 to 70 degrees. Thus, there is need for further investigation in this field, analytically, numerically and experimentally. Various hotels, lodges, and resorts are constructed without proper planning or mindset to attract and accommodate more tourists. Journal of Asian Earth Sciences, 2012.

What is the situation of Nainital today? The results of the present investigation provide a valuable insight into the seismic behavior of geosynthetic reinforced geostructures. Presently, the total of six landslide conditioning factors slope, aspect, elevation, curvature, land use, and rainfall has been selected for analyzing the spatial relationship with landslide occurrences. There are numerous images online of landslides on the Char Dham highways, such as these:- A landslide on the Char Dham highway network at Devprayag. It shows degree of susceptibility of area to landslide occurrences. The real-time monitoring of the Narendra Nagar landslide prone hill slopes involved a monitoring plan for immediate warning of landslide activity.
What are the causes behind landslides in Uttarakhand?
Monitoring Solutions by The Encardio-rite Group In keeping with the sensitivity of the Narendra Nagar Landslide site, the Encardio-rite Group offered a real-time monitoring plan of landslide-prone hill slopes. Eight years since the Kedarnath floods shocked the nation, Uttarakhand is still struggling with various landslides and floods every year. Also, the fact that the entire area of The flood disaster of 2013 is attributed to continuous heavy rainfall in the state from 15th June, 2013 to 17th June, 2013. The detailed article is available as: Yes agreed that Himalayan inherent character is fragile but if one compares the genesis of the landslides along those roads which is being widened and those roads which are not being widened in Uttarakhand the answer is human intervention has generated hundreds of landslide along Chardahm roads while the unwidened road having less than 5% landslides created in the monsoon period. For this, landslide inventory map was firstly constructed with 430 landslide locations identified from various sources with the help of GIS technology. Landslides are inevitable even without the action of humans.
Uttarakhand's Mussoorie 'highly susceptible' to landslides, finds study
Moreover, the illogical planning and utter ignorance of the people leave the land completely defenceless. A landslide occurred on the Rishikesh-Badrinath National Highway as heavy rainfall continued to lash parts of Uttarakhand for the third consecutive day. The detailed article is available on: In a recent study by Nath et al. Journal of Asian Earth Sciences, 2013. Whereas, the AUC value of prediction rate curve is 0.
Moreover, the creation of barriers or levees could help protect the communities that live near rivers or lakes when overflow Management of Mitigation after a Calamity Under long-term community recovery options, after a disaster the federal government has possibilities of conducting and allowing mitigation processes to ensure compensation for the affected victims. Education is the first step to prepare you to deal with any major disaster. As an engineer safety is the number one priority, it is the engineer 's job to note every possible danger that could happen while designing and constructing, if this is not done, disasters will occur. Environmental Earth Sciences, 2010. Nainital is one of the most landslide-prone areas in the state. . But in the fragile conditions of this area many landslides are inevitable during road construction unless high quality road engineering is adopted.
