Himalaya is youngest tectonic Active Mountain and northern boundary of India. Various infrastructure projects are under develop in Himalayan region for the better connectivity of peoples and national security of border line.  Widening of 295 km National Highway-44 in Jammu and Kashmir is an important developmental project. The highway passes through Outer Himalayan and Higher Himalayan sequences of rocks and is frequently affected by landslides at various places. The paper deals with 43 km Udhampur-Chenani and Nashri- Ramban section of the highway within sedimentary and metamorphic rock sequence. The area is prone to landslides on account of fragile geological, topographic and hydrological conditions. The study area has high rainfall intensity and numerous old landslides zones. During the project feasibility stage, project authority has identified the landslide prone area and suggested precautionary measures but during the construction work various unpredicted landslide and ground sinking events happened which given trouble in project construction cost and project completion time. In this paper, the challenges faced due to landslide and ground failure as failure of old slide adjutant to road construction, agriculture and residential ground failure at higher altitude due to road construction, collapse of high tension towers in cut slopes; its impact on construction activities; are discussed with  mitigation measures for unidentified landslide related challenges.

Abstract Novel Corona Virus “COVID 19” has affected worldwide. At initial stage the way out to curb the deadly virus was lockdown, isolating the symptomatic people, quarantining travellers and educate the people about the Corona virus so that precautionary measures are followed by people. local admistration has played vital role for highlighting the red zone areas and restricted the entry for people from outside to red zone areas in order to stop the infection from human to human transmission. The present research focus on application of Geographic Information System on mapping the Corona Virus cases in Jammu and Kashmir .The research attributes the role of dense Population and Urbanization are responsible for increasing the corona virus cases in the area. The districts like Srinagar and Jammu with high population and urbanization (census 2011) attributes high number of Corona cases in year 2020.The research experience that the Srinagar and Jammu attributes high population of 1236830 and 1529958 respectively than other districts of Jammu and Kashmir. This high population experiences highest number of Corona cases(Jammu 23339,Srinagar 24996), Deaths(Jammu 350,Srinagar 444) and COVID-19 recoveries(Jammu 22141,Srinagar 23957). The highly urbanised and populated area exposes the area towards infection. The high number of Corona Case experience heart related issues. The number of heart attacks in the state Jammu and Kashmir is rising which is alarming issue. This study will serve as replica study for managing COVID-19 in Jammu and Kashmir. The remote sensing and GIS was used to map the infected area and will be used for the future study in order to mitigate the impact of COVID-19 on life.

Hydropower is one of the cleanest, renewable and environmentally benign sources of energy. Nepal is blessed with immense source of water resources and huge hydropower potential. The Kali Gandaki ‘A’ (KGA) Hydroelectric Project is the largest hydropower project constructed so far in Nepal. The project is a daily pondage type scheme with an installed capacity of 144 MW. The KGA is one of the first largest hydropower projects that has been well studied environmentally and socially in the pre-project, construction and operation stages. A full team of multi-disciplinary professionals was involved during the construction phase to monitor environmental impacts and compliance with contract clauses, and to implement the mitigation measures. Implementation of KGA in what was once considered as a remote area, has resulted in multifold beneficial impacts to the local community. Improvement of public infrastructure, enhanced educational facilities and employment of local populations, including affected families during project construction and operation phase, have enhanced the quality of rural lives. The KGA operation has contributed significantly to Nepal’s power system and has boosted the economic development of the country.

PurposeThe study aims to find the causes of road projects implementation delays in Blantyre, one of the four city councils (CCs) in Malawi.Design/methodology/approachThe study followed a qualitative research approach using a Blantyre City Council (BCC) as a case study. This study combined in-depth, face-to-face interviews with councillors, secretariat staff, consultants, and contractors who worked on the city's road projects. Data gathered were analysed using thematic content analysis. Also, some road project documents were examined.FindingsThe findings from the case study revealed the primary cause of road project construction delays as the shortage of engineers in conducting detailed proposed projects surveys resulting in incomplete project scope definition before contractor's procurement. Other identified factors were service providers delaying the removal of existing public utility infrastructure from project sites, client funding issues, scope changes, and client delays in issuing instructions to the contractors during project implementation. Another factor was the shortage of construction equipment and construction materials experienced by some appointed contractors.Research limitations/implicationsOnly road construction projects and stakeholders operating from Blantyre city, Malawi, were contacted for the study; thus, the findings may not be generalizable.Practical implicationsThere is an urgent need to increase technical employees, especially engineers and other critical technical staff such as quantity surveyors in Blantyre. Employees' conditions of service should be conducive to attract qualified people to undertake effective management and assessment of projects before commencement to identify the feasibility of proposed projects to decrease the rate of road construction project delays.Originality/valueThe study has established Blantyre city's core challenges in implementing its road projects seamlessly and has provided mitigation measures for dealing with the shortcomings.

Landslides are one of the natural hazards that occur annually in Indonesia. A continuous geodetic observation in the landslide prone area is essential to support the precautionary measures. Because of its hilly topography, torrential rainfall and landslide history, the Ciloto district in Indonesia has been affected by ground deformation for an extended period of time. The purpose of our study is to detect significant movement and quantify the kinematics of its motion using the Interferometric synthetic aperture radar (InSAR) time series analysis and multi-band SAR images. We utilized the small baseline SDFP technique for processing multi-temporal SAR data, comprising ERS1/2 (1998–1999), ALOS PALSAR (2007–2009), and Sentinel-1 (2014–2018). Based on the detected deformation signal in the Ciloto area, the displacement rates are categorized as very slow movements. Two active main landslide zones; the Puncak Pass and the Puncak Highway area, which show the trend of slow movement progressively increasing or descreasing, were detected. The integration of the velocity rate between InSAR results and ground observations (e.g., terrestrial and GPS) was conducted at the Puncak Highway area from the temporal perspective. Using the polynomial model, we estimated that the area had cumulatively displaced up to −42 cm for 25 years and the type of movements varied from single compound to multiple rotational and compound.

<p>The floodplain of the Loire River around Orleans is a sinkhole-prone area due to the highly karstified calcareous Beauce Formation overlying by few meters of weathered materials and alluvial deposits. Such layout makes it necessary to carry out detailed geotechnical and hydrogeological investigations for any important building project.</p><p>This paper presents the first results of a study carried out by the French Geological Survey for a bridge project across the Loire River. The geological setting indicates that the study area is near the front door of a supposed-major cave system in which water, coming from the Loire River, not only provides drinking water for an important part of the region, but also supplies the main spring of the Loiret River, located a few kilometers further. The overview of past sinkhole collapses confirms that the study area is regularly concerned by ground collapses of several meters of diameter. Field investigations include microgravimetry (26 hectares), two electrical resistivity profiles (720 m and 470 m long), 149 cone penetration tests (around 15 m deep), a first sequence of 11 drillings (40 m deep) and videos, gamma-ray and sonar logs. A first sinkhole hazard assessment is now quite complete: very weak layers (possibly caves) of several decimeters to a few meters thick need specific mitigation measures to secure the construction project. Other investigations are still being analysed (a second sequence of drillings, dye tracing, injection of salt brine with resistivity profiling) and should help specify the area hydrogeological hazard.</p>

Precautionary Measures

Abstract. Building houses in inundation areas is always a risk, since absolute flood protection is impossible. Where settlements already exist, flood damage must be kept as small as possible. Suitable means are precautionary measures such as elevated building configuration or flood adapted use. However, data about the effects of such measures are rare, and consequently, the efficiency of different precautionary measures is unclear. To improve the knowledge about efficient precautionary measures, approximately 1200 private households, which were affected by the 2002 flood at the river Elbe and its tributaries, were interviewed about the flood damage of their buildings and contents as well as about their precautionary measures. The affected households had little flood experience, i.e. only 15% had experienced a flood before. 59% of the households stated that they did not know, that they live in a flood prone area. Thus, people were not well prepared, e.g. just 11% had used and furnished their house in a flood adapted way and only 6% had a flood adapted building structure. Building precautionary measures are mainly effective in areas with frequent small floods. But also during the extreme flood event in 2002 building measures reduced the flood loss. From the six different building precautionary measures under study, flood adapted use and adapted interior fitting were the most effective ones. They reduced the damage ratio for buildings by 46% and 53%, respectively. The damage ratio for contents was reduced by 48% due to flood adapted use and by 53% due to flood adapted interior fitting. The 2002 flood motivated a relatively large number of people to implement private precautionary measures, but still much more could be done. Hence, to further reduce flood losses, people's motivation to invest in precaution should be improved. More information campaigns and financial incentives should be issued to encourage precautionary measures.
