Water is fundamental to all aspects of human and economic development, so protecting riverine ecosystem is vital. Environmental flow assessment is widely applied to describe how much a river ecosystem changes with alterations to its natural flow regime. This study aimes to assess the environmental flow of Stung Chinit basin, one among the 12 tributaries contributing to Tonle Sap Great Lake, caused by the changes in river flow regimes under future

Phnom Penh, the capital city of Cambodia, has had a rapid increase in urbanization in recent decades. As impervious area increases, urban runoff becomes an increasingly more important component of urban non-point pollution. Boeng Trabek catchment is highly susceptible to flash flooding during heavy storm events. This study evaluates the relationship between the peak discharge and water quality, and assess the impact of land use scenarios on urban

Report of UNICEF, 2009 has shown that region along Mekong River in Cambodia has arsenic (As) pollution in groundwater. The major cause of As pollution was attributed to natural process such as the dissolution of As-containing minerals and anthropogenic activities such as percolation of water from mining waste. Cambodia has been recorded a higher concentration of arsenic in groundwater of several provinces including Kandal, Kampong Cham, Prey Veng

Cambodia is lack of surface water in the dry season for serving the need of people in rural area. Another potential source of water may be groundwater, a supplement source to rainwater and surface water for additional irrigation of the wet season and dry season crop. It probably serves the needs of most of the rural and urban population. Being an integral part of the hydrological cycle, its availability depends on the rainfall and recharge condit

As a consequence of the global warming effects on rainfall changes such as droughts, hail storm or flash flood, data sets of highest daily rainfall for the period (1981-2010) were used for calculating the statistical distribution of extreme monthly rainfall in tributary of Tonle Sap Basin (Stung Chinit Catchment, Kampong Thom Province). The main objective of this paper is to develop the return period of rainfall and estimate depth of rainfall fro

The Internet of Things is considered as the next big technology revolution after the invention of the Internet. Data of IoT are very useful and could produce such huge creativity for us to build many useful applications in our daily life. In Cambodia, the IoT is still a new technology for research and development. However, Security and Privacy are the main key issues for IoT and they are still facing some enormous challenges such as DDoS Attack o

Glass, a fragile material that gains popularity in building construction, has been developed to sustain with high loads. This structural glass would not work effectively if the connection has not been able to transfer the loads properly. The study aims to optimize bolted connection of structural glass. We focus on the geometry optimization of the bolt to deal with heavy external loading that requires a strong connection. Numerical parametric stud

This study attempts to investigate size distribution of particulate matters emitted from medical waste burning and ambient air quality of a hopistal in a remote area of Cambodia. The particulate matters are mainly discussed in different size ranges of 0.1-10 µm, which was sampled by a nano-sampler on a single chamber incinerator (SCI) and a stella incinerator (SI). In addition, carbonaceous aerosols and gaseous pollutants were also included. The

Drought is one of the main natural disasters that have affected agriculture and rice production in Cambodia. The main objective of this study is to assess the drought in the Cambodia Mekong Delta using different drought indices (Standardized Precipitation Index (SPI), Percent Normal Index (PNI) and Decile Index (DI). The results showed that Index (PCI) values ranged from 14.79 to 16.69, meaning that the rainfall pattern of the study area is seaso

The study aimed to analyze rainfall trend in Tonle Sap Lake regions of the Lower Mekong Basin and to determine if these time series belonged to a similar regime, have had any significant trends. To reveal the behaviors of annual and monthly rainfall for trends, historical data series of available 6 stations in more than 30 years from the 1980s to 2012 were used in this study. From the basic daily rainfall data, total and means of monthly and annua
