Projects With Foreign Collaboration

 

Sri Lanka being a vulnerable small island is becoming more and more prone to various hazards. Localized extreme rains during monsoons and pre-cyclonic rains during storms in Bay of Bengal bring heavy downpours that trigger landslides and slope failures and cause floods in lower plains and sometimes even in areas where floods are very uncommon. Due the effect of climate change impacts, their occurrence has been observed as in an increasing trend. This necessitated proactive actions to minimize their adverse impacts and NBRO is pioneering in soft and hard mitigation activities in view of building disaster reselience in the country. Given below are some of the major long term projects NBRO implements in collaboration with international donor agencies and foreign institutions.

 

 

  • Technical Cooperation for Landslide Mitigation Project (TCLMP)

  • Projects of Climate Resilience Improvement Program (CRIP)

  • NBRO – Norwegian Geotechnical Institute Technical Cooperation Project

  • NBRO – Vanderbilt Institute for Energy and Environment Technical Cooperation Project (ADAPT-SL)

  • NBRO-UNDP Technical Cooperation Project for Enhancing Real Time Landslide Forecasting and Early Warning Capacity of NBRO

  • NBRO – Asian Disaster Preparedness Centre Technical Assistance Project

  • NBRO - International Consortium of Landslides Technical Cooperation Project

  

Technical Cooperation for Landslide mitigation Project [TCLMP]

 

NBRO has been working in collaboration with Japanese International Cooperation Agency (JICA) in landslide risk management in the country for a considerably long period. JICA often extended their technical and financial assistance to NBRO. The technical assistance received from JICA became very important to NBRO especially through two recent projects namely Technical Cooperation for Landslide Mitigation Project (TCLMP) and Landslide Disaster Protection Project (LDPP), to which the Government of Japan provides both the technical and financial assistance through JICA.

 

Objective of the TCLMP is to enhance the capacity of NBRO in structural mitigation of landslides and of LDPP is the stabilization of unstable roadside slopes in the national highway network in the hill country done in collaboration with the Road Development Authority.

 

However, the landslide threat in the country is real and more counter effort will be necessary to lower landslide threat. Hence continuation of JICA assistance will be critical necessity. NBRO proposes to continue more projects with JICA collaboration and with JICA assistance in the future. Proposed activities will address both structural and non-structural mitigation measures to counter landslide threat in the country.

 Landslide Mitigation under TCLMP

In TCLMP, the JICA had an office at NBRO staffed with a team of Japanese technical experts in landslide risk management, of which some members were resident in Colombo whereas the others frequently visited Sri Lanka. The JICA experts under the leadership of Mr. Kenichi Handa, professional landslide engineer and expert from the Government of Japan, worked at NBRO Head Office and in the field. They designed and implemented the mitigation measures of four major landslides in Nuwara Eliya, Matale, Badulla and Kandy districts successfully. Financial and technical assistance of this project is given by the Japan International Cooperation Agency. They trained NBRO staff especially the geologists and geotechnical engineers. Implementation of planned mitigation measures is almost complete whereas post-project monitoring activities are now in progress.

Projects of Climate Resilience Improvement Program [CRIP]

 Climate Resilience Improvement Project (CRIP) is a joint effort of Government of Sri Lanka and World Bank with the hopes of reducing the adverse impacts of climate change in the country and adopting to the stock of infrastructure to extreme climate shocks. The Project as a whole is being executed by Ministry of Irrigation and Water Resources Management (MIWRM) with the financial assistance of International Development Association (IDA) – World Bank. A main component (ensuring the transport continuity – CRIP Road Project), and a subprogram (CRIP School Protection Program) of the Project is being implemented by National Building Research Organisation. The Project is executed in two phases.

CRIP Components Implemented by NBRO

  • CRIP Transport Continuity Project

  • School Protection Subprogram

  • CRIP Provincial Road Project – Uva Province

CRIP Transport Continuity Project

Project Background 

The Road Development Authority (RDA) implements the Transport Continuity Project component of the CRIP Project, which includes the stabilization of landslides and slope failures observed along several selected roads. Therefore, National Building Research Organisation (NBRO) as the national focal point in landslide disaster management, was entrusted to (i) investigate the sites affected by landslides or slope failures along the selected roads, (ii) design structural measures to stabilize the investigated unstable sites, and (iii) to supervise the implementation of designed stabilization measures.

During the recent years the country has observed an increased trend of occurring landslides and according to the NBRO’s records, most of the recent landslides are associated with the slope cuts along the sides of the roads in hilly areas. Landslides at Paradeka along Kandy – Gampola road, Between culverts 50/2 – 50/50 along Thennekumbura - Ragala road, landslide at Moragahamula on Kandy - Mahiyangana road, landslide at Nuwaraeliya – Welimada road and the rock fall threat on Beragala - Wellawaya road among many. During the rainy seasons, the road users are frequently interrupted by the sudden road closures while facing a risk on their lives as well.  The interruptions to transportation often cause negative impacts on the livelihoods, health, education, and economy of the country.

NBRO’s 30 years’ experience in executing landslide disaster risk reduction measures and related studies has paved the way to undertake the investigations, designing and supervision of slope stabilization along the roads selected under the Transport Continuity project. NBRO is currently involved in investigating, designing and construction supervision of the landslides observed along the following roads:

 

  • Landslides along the Kandy - Mahiyangana – Padiyathalawa road (A026)
  • Landslide at Haggala along the Peradeniya - Badulla – Chenkaladi road (A005)
  • Landslide at Ginigathhena along the Nuwara Eliya – Hatton road (A007)
  • Landslide at Beragala (Mahagalagawa) along the Colombo – Ratnapura Wellawaya road (A004)
  • Landslide at Beragala along the Colombo – Ratnapura Wellawaya road (A004)
  • Landslide at Kithulgala along the Awissawella – Hatton Nuwara Eliya road (A007)
  • Landslide at Kaluaggala along the Colombo – Ratnapura Wellawaya road (A004)

 Landslide along Hanguranketha – Ragala road  Landslide along Kandy – Gampola road at Paradeka
 Landslide  along Nuwaraeliya - Welimada road  Landslide  along Kandy – Mahiyangana road

A few of the roadside landslides occurred during the recent years

 

Current Progress

Landslides along the Kandy - Mahiyangana – Padiyathalawa road  

Landslides, rock failures and cut failures along the Kandy - Mahiyangana – Padiyathalawa road have been of a constant threat and source of headache to the road users over the past years. By considering the national interest and as per the request made by Road Development Authority (RDA), National Building Research Organization (NBRO) has investigated the affected areas and identified appropriate mitigation measures to minimize the associated risks.

 One of the locations with high threat of rock fall before mitigation
 Rock fall observed at one location between culverts 55/3 and 55/6
Slope failure observed another location between culverts 55/3 and 55/6

 

Altogether 18 locations were selected for rectification work along the Kandy – Mahiyangana -Padiyathalawa road. The mitigation works included soil nailing, retaining wall construction and drainage improvement. Mitigation work at 17 of these locations are completed while the construction work are still being carried out at Location 8. This project has successfully increased the safety of the road users as well as reducing the constant disruptions due to closure of different sections of the road due to cut slope failures and rock fall threats.  

Mitigated locations

Mitigation works in progress

 

Haggala Landslide

Tilted wall by the Nuwara Eliya - Badulla road in between culvert 75/6 and 75/7

 

Several landslides have taken place along the Budulla – Nuwara Eliya main road between Culverts 75/5 and 76/5. The location is in close proximity to the Haggala Botanical Garden. These locations are identified to have a very high possibility for further failures. Therefore, appropriate stabilizing measures are to be adopted at these locations to ensure that further progressive failure is prevented and safety margins of all existing slopes are enhanced to an acceptable level. 

 

Ginigathhena Landslide

Numbers of cutting failures have been occurring at the  no. 48/2, near Ginigathhena area at Avissawella-Hatton-Nuwara Eliya Road (A007), affecting the transportation activities. Further, a mass movement had occurred on 22nd June 2014 followed by the excavation works at the toe of the soil slope in question. Further, it was reported that there was no rain at the time of failure, but it has been further activated with continuous heavy rain received later into the area. In order to prevent further failures and obstructions to one of the major transport routes in the country, this location was selected to be mitigated under the Project.

School Protection Program

Project Background 

Since 1986, the government of Sri Lanka has undertaken various preparedness and mitigation measures to minimize the landslide disaster risk in the central highlands of Sri Lanka. Landslide hazard zonation mapping, regulation of landuse and development activities in hilly terrains, capacity building of stakeholder agencies, public awareness and education can be highlighted among such measures implemented and carried out by the Government through National Building Research Organisation (NBRO).

During the recent years of 2003, 2007, 2010 and 2011, several schools in the Central Province had been affected by landslides and slope failures causing trauma among the school communities as well as the concerned general public.  In the light of this situation, in February 2011, NBRO submitted to the government a proposal for mitigation of the most critical landslides in the hilly districts. The proposal also emphasized the need for mitigation of 30 locations where schools are affected by landslides including 18 schools in the Kandy district, 06 schools in the Matale district, and another 06 schools in the Nuwara Eliya district.

A number of those schools identified in NBRO’s year 2011 proposal were repeatedly affected by landslides during the rainy seasons in successive years also. Considering the landslide threat on the lives of thousands of young children, school staffs, parents, and related many others, there was an urgent need of mitigating the landslides located in the above mentioned school premises. Therefore, NBRO and the Ministry of Disaster Management separated out the issue on the landslide risk reduction in schools and submitted a new technical proposal in the year 2013. Considering the high cost involved, rectification of landslides in school premises was proposed to be carried out in a phased out approach, and under the technical proposal submitted, “Mitigation of Landslide Impact on Schools in the Kandy District” is addressed.

In October, 2013 NBRO was informed by the Government of the acceptance of NBRO’s proposal for Mitigation of Landslide Impact on Schools in the Kandy District for funding by the World Bank under the School Protection project of the Sri Lanka Comprehensive Climate Risk Mitigation Program.

The School Protection Program is a $7 million investment on 18 schools from Kandy district identified to be highly vulnerable to landslides threat (benefiting approx. 30,000 students). This project is expected to address the occasional interferences to the education these schools have to face annually during the rainy seasons.

NBRO – Norwegian Geotechnical Institute Technical Cooperation Project

 

 

NBRO in collaboration with the Norwegian Geotechnical Institute (NGI) continues the project "Institutional Cooperation on Mitigation of Natural Disasters due to Climate Change".

Geological Survey of Norway also assists in the interpretation of INSAR satellite imagery and aerial maps in the trend analysis of ground subsidence in affected areas.

Norwegian Geotechnical Institute (NGI) is a world-renowned geotechnical institute with extensive experience in global studies.

NGI donated several automated rain gauges coupled with instruments to measure soil moisture, connected to the rain gauge network of the Landslide Early Warning System of NBRO.

NGI donated Ground Penetration Radar (GPR) equipment to NBRO that is used by NBRO in ground subsidence studies.

NGI sent a team of NGI experts and assisted NBRO in 2015 to conduct a study on the suspected oil contamination of ground water in Jaffna Peninsula.

Another NGI team visited NBRO and conducted aerial 3D mapping exercise with NBRO staff using a camera drone.

NGI also donated a latest camera drone and a state of the art computer with fast multiple processors for image processing to obtain the orthomap & digital elevation models. This equipment is now used by NBRO in many applications ranging from landslide mapping, settlement mapping, land use mapping and other related work.

A team of NBRO staff were trained by the NGI in Norway on ground penetration studies, land subsidence and ground remediation.(For more details please refer: NBRO Newsletter Vol 35 of October2016,Technical Co-operation for Mitigation of Natural Disasters Due to Climate Change in Sri Lanka).

 

NBRO -Vanderbilt Institute for Energy and Environment (VIEE) Technical Cooperation Project

 

Field survey in progress

 

NBRO’s collaboration with Vanderbilt Institute for Energy and Environment (VIEE) of USA started in 2010.

 

The two institutions initiated a five year study "Agricultural Decision-making and Adaptations to the Precipitation Trends in Sri Lanka" (ADAPT-SL) from 2012.Climate Research Unit (CRU) of NBRO was established to conduct the study. This project concludes in August 2017.

 

Project Brief: Water scarcity is a reality especially in the past few years to farmers in the North Central Province. They depend on either rain or irrigation water to grow paddy and find them challenged by this situation and understand that adaptation to new farming practices such as crop diversification is required without relying on traditional practices to manage water. Information gathered on farmer decision-making and perceptions of the challenges will be analysed to facilitate farmer decision making and making policy recommendations for the benefit of agricultural communities.
