Tel : +94-112 665170 Fax : +94-112 665170 Content by : Photographs : Layout & Designing : Garvi Design Studio Printed by Garvi Design Studio 2 Sri Lanka Floods and Landslides - May 2016 | Post-Disaster Needs Assessment Foreword In the month of May 2016, parts of Sri Lanka were hit by the heaviest recorded rainfall in more than 18 years, which caused severe floods in 24 districts and also horrific landslides, one of which was the worst recorded in our country. The floods and landslides resulted in the loss of at least 93 lives and affected almost half a million people. The disaster damaged over 58,000 houses and caused a loss in income for over a million people dependent on agriculture, trade and industries. In the aftermath, extensive relief operations were conducted at national, provincial, district as well as divisional levels, significantly supported by the Sri Lanka Army, Navy and Air Force, civil society organisations, the private sector as well as individual contributions. As we now move on from the immediate relief phase, the subsequent recovery phase has been initiated by a Post-Disaster Needs Assessment (PDNA). This PDNA used a methodology, which was developed jointly by the United Nations, the World Bank and the European Union. -
Distribution of Cylindrospermopsis Raciborskii (Cyanobacteria) in Sri Lanka

Majority of these water Water heritage of Sri Lanka consist of 103 major resources are known to be contaminated with different river basins radiating from the hill country to the types of toxigenic cyanobacteria making water lowlands and over ten thousand operational unsuitable for human and animal consumption. reservoirs (Fernando, 1993). Historical evidence Cylindrospermopsis raciborskii, a toxin producing suggests that the origin of many of these tropical cyanobacterium, recently recorded at high reservoirs especially in the dry zone, date back to abundances in lentic waters of the country. This pre-Christian era during the period the country species is highly adaptive and exhibit different morphotypes: straight, coiled and sigmoid- shaped known to be self sufficient in agriculture trichomes under different environmental conditions. (Arumugam, 1969). In contrast, reservoirs Distribution and abundance of the species is mainly constructed during the recent history are used depending on the environmental factors and therefore mainly for hydroelectric power generation, remedies can be proposed to keep the populations irrigation and domestic use, though few under control. This preliminary study was conducted reservoirs are used exclusively for drinking. -

Chapter 5 Plan of Proposed Water Supply System
CHAPTER 5 PLAN OF PROPOSED WATER SUPPLY SYSTEM Preparatory Survey on Anuradhapura North Integrated Water Supply Project Final Report (Main) CHAPTER 5 PLAN OF PROPOSED WATER SUPPLY SYSTEM 5.1 Water Intake Works 5.1.1 Selection of Water Intake Method This section reviews the various intake methods such as the intake well, pontoon, rail and canal types in order to decide the most suitable intake method for this Project. Table 5.1 Comparison of Intake Method Method Outline Image Intake well This method is commonly used in lakes and reservoirs. It is an option for vertical intake levels if some intake holes are made on the well’s wall. Even if the water level varies significantly a stable intake is expected. Foundation should be stable. The construction cost is higher than other methods if the water depth is large. Pontoon This method is proposed as a tentative facility, if construction on the reservoir is not possible. The pump and electrical panels are installed on a metallic float, which needs to be connected by wire to anchors. The location of the intake can be moved. This method is not suitable if the water level varies significantly. Installation is not difficult and the cost is economical. Inclined rail This method is proposed as a tentative facility, if construction on the reservoir is not possible. A rail is installed on the incline of the bank, and the pump position is moved to suit the water level. Installation is not difficult and the cost is economical. Canal Intake Water is taken from the existing irrigation canal, which is operated by the Irrigation Department. -

Yet, it was able to get the approval from cabinet of Ministers to assign the EIA study and Geological Survey under the 1st phase of the project to the CAMC Engineering Company Ltd after discussing with them whom the contract agreement was made. It was able to get the EIA approval for the Thalpitigala Reservoir Project and it was expected to negotiate with EXIM Bank of China for funding through the Department of External Resources. Lower Malwathu Oya Reservoir Project is one of the important projects which funds have been allocated under the Ministry. By end of 2016, Cabinet approval was obtained to award Engineering, Procurement and Construction (EPC) contract to the CAMC Engineering Company Ltd of China and they were asked to submit technical and financial reports. The initial works for the recruitment of staff for the Gin Nilwala Diversion, Thalpitigala and Lower Malwathu Oya Reservoir projects were already commenced at the end of the year 2016. It is to be noted that the Climate Resilience Improvement Project has reached to 32% of cumulative physical as well as financial performance at the end of 2016. -

Environmental Flow in Sri Lanka: Ancient Anicuts Versus Modern Dams
3 Sri Lanka J. Aquat. Sci. 19 (2014): 3-14 Environmental flow in Sri Lanka: ancient anicuts versus modern dams 1* 2 3 E.I.L.SILVA , HERATH MANTHRITHILAKE , DAMMIKA PITIGALA and E.N.S. SILVA1 1Water Resources Science and Technology, 77/2, Hettiyawatte, Elapitiwela, Ragama, Sri Lanka 2International Water Management Institute, 127 Sunil Mawatha, Pelawatte, Battaramulla, Sri Lanka 3Sri Lanka Mahaweli Authority, Ministry of Irrigation and Water Resources Management, 500, T.B. Jaya Mawatha, Colombo 10, Sri Lanka * Corresponding author: [email protected] Abstract Environmental flow describes the stream flow (quantity and regime) required to sustain upstream and downstream habitats, riparian vegetation, human livelihoods and wildlife. When natural rivers or tributaries are held back by weirs, anicuts, barrages or dams, for a variety of purposes such as diversion for irrigation, hydropower generation or flood control often the downstream flow requirement is ignored or neglected. Although there is no universally accepted definition, convention or law on environmental flow, it has been now recognized that environmental flow is essential for sustainability of riparian ecosystem and their services, which are essential for our own existence, livelihoods and many more. This paper looks at physical structures constructed across rivers and tributaries in Sri Lanka since ancient times to date (including mini-hydro power stations) with a view to understand whether simple ancient wisdoms are more appropriate than modern structures for nature conservation. There are tangible evidence to defend that the ancient anicuts known as “amuna” surged sufficient water in tributaries and rivers, to sustain the environment than modern engineering works which has created dead river beds immediately downstream in many streams and rivers. -

During the year, the Ministry was able to commence the construction of head works of Moragahakanda and Kaluganga reservoirs, which have been delayed for many years due to constraints of funding, can be considered as land mark achievement. We could also accelerate the implementation of ongoing water resources development projects during this year. We could complete the reservoir and main canal construction of Rambukkan Oya reservoir project in Ampara District at the end of year 2012 spillway gates to be completed and reservoir can be completed in mid-2013. We were able to expedite the constructions of Deduru Oya reservoir project and the head works of the project will be completed by mid- 2013.
