On 11 May 2017, Cambodian young professionals from Department of Rural Engineering at Institute of Technology of Cambodia helped in organizing a forum on “Water Corner” under the topic of Reforming a Water Sector: How to Inspire the Next Generation? In this special event, H.E. Ek Sonn Chan, Secretary of State, Ministry of Industry and Handicraft of Cambodia was invited to be the honorable quest speaker. Mr. Ek Sonn Chan had become the director of Phnom Penh Water Supply Authority (PPWSA) from 1993 to 2011. He shared to the participants about his experience and lesson learnt including challenges and opportunity during his works for PPWSA. With his leadership principle and strong commitment, he has made significant improvement in terms of administrative and technical works in PPWSA. Since then, PPWSA successfully rehabilitated the malfunction water supply system by increasing the distribution network to deliver safe water to million people in Phnom Penh city and water loss was reduced from 72% of the total water production in 1993 to only about 6% in 2011. From his effort with good achievement, he and PPWSA have been awarded with many regional and international recognitions. Furthermore, H.E. Ek Sonn Chan also highlighted potential working opportunities in water sector and encouraged the students to have strong commitment with working professionally. He also expressed his concern about society and reminded the young generation to start considering and changing for better living society. The pictures below show some activities during Water Corner forum.
Through the cooperation between Institute of Technology of Cambodia (ITC) and Asian Development Bank (ADB), the 5th year students from Department of Rural Engineering who receive scholarship support from ADB need to accomplish an educational field trip in order to learn on the actual engineering practices as well as management in the field specifically on water resources and rural infrastructure.
This year, Department of Rural Engineering of ITC has organized an educational field trip for the 5th year students under ADB’s scholarship program to Siem Reap province. This field trip aimed to help the students to build up their knowledge and know-how on water management and hydraulic structures development at the field within Angkor’s area under authorization of APSARA National Authority (APSARA). In the spirit of good cooperation so far, ITC has formally requested to APSARA for permitting a group of students and lectures to fulfill this field trip in Angkor’s area. Accordingly, APSARA has approved and requested to submit a report after completion. Moreover, APSARA has assigned technical staffs from Department of Water Management to facilitate and guide the students to learn about their projects at the specific sites in Angkor’s area.
The educational field trip has been carried out for 4 days from 13th to 16th February, 2017. This field trip was led by three lecturers from Department of Rural Engineering of ITC (Dr. Chhuon Kong, Dr. Hak Danet, Mr. Kem Chom) and participated by 29 students from Department of Rural Engineering, who receive ADB’s scholarship support.
The specific places to visit in Angkor’s area were: Department of Water Management of APSARA National Authority, Sras Srang Reservoir, Krang Kroch trees plantation field, Ta Som check-structure, North Baray (Jayatataka), Neak Pean ancient water filtration (middle of Nort Baray), Phreah Khan Temple drainage system, Angkor Thom’s moat, Trapeang Kchhorng Sedimentation basin, Sedimentation trapping channel connected to Angkor Wat’s moat, West Baray (Suryatataka) and hydraulic structures of Chaw Srei Vibol Temple (North and South moat, connection channel, check structure). Below are some photos of activity taken during the field trip.
This 4-day educational field trip was completed with the fruitful outcomes. It provided good lesson learnt particularly for the students to understand about water management and hydraulic structure including the ancient and present hydraulic network in Angkor’s area. Notably, water management in Angkor’s area is significantly challenged since there are 4 main purposes to be concerned on:(1)Supply and maintain water in the moats systems in Angkor’s area; (2)Store and release the water to avoid flooding in Siem Reap during wet season; (3)Store and release water for irrigation system and other uses; (4)Clear and clean the water before supplying to the moat system in Angkor’s area; (5)Explore the ancient hydraulic system to rehabilitate with maintaining cultural landscape, preserving all authenticity and safeguarding the integrity for sustainable development in Angkor’s area. Impressively, on the third day of field trip, the students got interviewed by media staffs from department of communication of APSARA about their impression and activity during the field trip. The news of this field trip and the interview was published in the website of Apsara National Authority. Furthermore, this educational field trip helps to further strengthen relationship and closer cooperation not only between technical staffs and lecturers/students but also between institutions.

Heng, S., Ly, S., Chhem, S., Kruy, S., 2016. Analysis of public perception on urban flood in Phnom Penh, Cambodia. The International Conference on Water Security and Climate Change: Challenges and Opportunities in Asia, 29 November–1 December 2016, Asian Institute of Technology, Bangkok, Thailand.
Abstract: A remarkable population and economic growth has been seen in Phnom Penh, a center of commerce, tourism and residence. Urbanization in this capital city of Cambodia, changes of land cover from pervious to impervious areas, and the climate change phenomenon introducing a more intense rainfall within a short time, have led to frequent flooding during the rainy season. Human activities might be a main contributing factor to urban floods in this area. To propose a sustainable measure for such water-related hazard, understanding on public perception is one among various important issues to be considered. This study is aimed at analyzing public perceptions on urban flood in Phnom Penh. A questionnaire survey on 100 samples was conducted within four dense districts of the city. Key findings of the survey are: (1) flood depth of 0.15-0.30 m and flood duration of less than 1 h was very common since it is a rainfall-flood phenomenon, no overflow from rivers; (2) the impacts were greatly on small businesses and health of citizens; (3) most of the people did nothing when there are flood occurrences because flood water does not flow into their house; (4) garbage in the drainage system reduced the flood flow capacity; and (5) education on water engineering and effective garbage management were recommended by citizens to solve flood problems on a long term basis. These results might urge the government to take immediate actions on this extreme event. They also provide essential information for proposing a sustainable flood management strategy.
Hok, P., Oeurng, C., Heng, S., 2016. Estimation of water availability in rivers of Stung Sreng Basin, Cambodia, using HEC-HMS. The International Conference on Water Security and Climate Change: Challenges and Opportunities in Asia, 29 November–1 December 2016, Asian Institute of Technology, Bangkok, Thailand.
Abstract: River system of the Tonle Sap Lake plays an important role in ensuring a long-term economic growth in Cambodia, meaning that water supply for domestic consumption, agriculture and environment, etc. must be sufficient. Stung Sreng is one among 11 main rivers of the lake system and it comprises of four ungauged tributaries: Stung Srang, Stung Sreng, Stung Tanat and Stung Phlang. Stung Sreng has the biggest drainage area and lies in the world tourism site of Siem Reap province. A remarkable increase in number of tourists of over two million visiting Siem Reap in 2015 and the government’s target of exporting one million ton of rice per annum have posed a great concern on water security. Water from Stung Sreng might be used for tourism sector only. Therefore, analysis of water availability from each tributary is absolutely indispensable. HEC-HMS was applied to calibrate and validate daily streamflow at a station where observed data is available. Indicated by three error indices, accuracy of the model prediction was concluded as satisfactory. The successfully calibrated HEC-HMS model was then employed to estimate water availability. The annual streamflow of Stung Srang, Stung Sreng and Stung Tanat River was estimated at 419, 686 and 230 MCM, respectively. The total yield from the whole basin is about 1572 MCM per year. The available water of 686 MCM/year from only Stung Sreng will be sufficient for tourism sector in Siem Reap, whereas the remaining amount of 886 MCM/year can be used for agriculture and other purposes.
Seng, T., Ly, S., Heng, S., 2016. Feasibility study of a micro-hydropower project based on economic analysis: a case study of a remote area in Cambodia. The International Conference on Water Security and Climate Change: Challenges and Opportunities in Asia, 29 November–1 December 2016, Asian Institute of Technology, Bangkok, Thailand.
Abstract: As a developing country, Cambodia is requiring a lot of energy to sustain its development. In this context, the Royal Government of Cambodia considers hydropower as a priority sector due to a favourable condition of its natural resources. Since the national grids are unable to link the remote areas and large scale projects commonly introduce high impacts, a micro-hydropower scheme is preferable for rural electrification. This paper aims to study, based on economic analysis, the feasibility of O Katieng micro-hydropower project located in a remote area of Cambodia. Two key materials required for the design of micro-hydropower are topography and long term streamflow information. SWAT model was used to estimate streamflow because of the absence of observed data in the study area. From the flow duration curve, three alternatives of design discharge (2.483, 1.470 and 0.746 m3/s) were selected for proposing the hydropower development scheme and conducting economic optimization. The preliminary results suggest an installed capacity of each alternative as 269 kW, 159 kW, and 79 kW. The corresponding unit production cost of USD 9.32, 11.02 and 15.79 Cent/kWh are considered as feasible comparing to the current average electricity price in Cambodia (approximately USD 20 Cent/kWh). Overall, the development scheme with a designed discharge of 2.483 m3/s was recommended because it generates the highest amount of energy (1.54 GWh/year) with the lowest production cost.
