“…However, application of joint analysis of flood variables is still very limited for flood analysis in Malaysia. Increasing risk of flood in recent years has posed a major challenge in the Malaysian development [14], [15]. A number of recent studies revealed increasing frequency and severity of rainfall extremes in peninsular Malaysia [16], [17].…”

Bivariate frequency analysis of flood variables of different station locations of Kelantan river basin was conducted using copula for the assessment of the geographical distribution of flood risk. Seven univariate distribution functions of flood variables were fitted with flood variables such as peak flow, flood volume, and flood duration to find the best-fitted distributions. The joint dependent structures of flood variables were modeled using Gumbel copula. The results of the study revealed that different variables fit with different distributions. The correlation analysis among variables showed a strong association. Joint distribution functions of peak-flow and volume, peak-flow and duration, and volume and duration revealed that the joint return periods were much higher than univariate return periods of same flood variables. The flood risk analysis based on joint return period of flood variables revealed the highest risk of devastating flood in the downstream. The locations identified as highly susceptible to flood risk by joint distributing of flood variables had experienced most severe floods in recent history, which indicates the effectiveness of the method for the analysis of flood risk. It is expected that this procedure can be helpful for better assessment of flood impacts.

“…The general characteristics of the rivers are summarized in Table 1. The area is located near the equator, with a tropical climate characterised by uniformly high temperatures, high humidity and abundant rainfall [27]. It has an average annual rainfall of 2300 mm and a mean daily temperature between 21 °C and 32 °C [28].…”

Predicting the impact of climate change and human activities on river systems is imperative for effective management of aquatic ecosystems. Unique information can be derived that is critical to the survival of aquatic species under dynamic environmental conditions. Therefore, the response of a tropical river system under climate and land-use changes from the aspects of water temperature and dissolved oxygen concentration were evaluated. Nine designed projected climate change scenarios and three future land-use scenarios were integrated into the Hydrological Simulation Program FORTRAN (HSPF) model to determine the impact of climate change and land-use on water temperature and dissolved oxygen (DO) concentration using basin-wide simulation of river system in Malaysia. The model performance coefficients showed a good correlation between simulated and observed streamflow, water temperature, and DO concentration in a monthly time step simulation. The Nash-Sutcliffe Efficiency for streamflow was 0.88 for the calibration period and 0.82 for validation period. For water temperature and DO concentration, data from three stations were calibrated and the Nash-Sutcliffe Efficiency for both water temperature and DO ranged from 0.53 to 0.70. The output of the calibrated model under climate change scenarios show that increased rainfall and air temperature do not affects DO concentration and water temperature as much as the condition of a decrease in rainfall and increase in air temperature. The regression model on changes in streamflow, DO concentration, and water temperature under the climate change scenarios illustrates that scenarios that produce high to moderate streamflow, produce small predicted change in water temperatures and DO concentrations compared with the scenarios that produced a low streamflow. It was observed that climate change slightly affects the relationship between water temperatures and DO concentrations in the tropical rivers that we include in this study. This study demonstrates the potential impact of climate and future land-use changes on tropical rivers and how they might affect the future ecological systems. Most rivers in suburban areas will be ecologically unsuitable to some aquatic species. In comparison, rivers surrounded by agricultural and forestlands are less affected by the projected climate and land-uses changes. The results from this study provide a basis in which resource management and mitigation actions can be developed.

“…Sejak tahun 1951, suhu permukaan di Malaysia meningkat sebanyak 0.18°C pada setiap dekad (Shahid et al, 2017). Semasa tempoh 1969 sehingga 2009, peningkatan suhu permukaan Malaysia direkodkan pada kadar 0.6-1.2°C bagi setiap 50 tahun (NRE, 2011).…”

Abstrak: Perubahan iklim adalah perubahan corak iklim disebabkan oleh punca semula jadi dan antropogenik yang mempengaruhi aktiviti manusia dan ekosistem semulajadi. Senario masa depan (2025-2034 dan 2041-2050) menunjukkan kenaikan suhu permukaan sebanyak 1.6-2.3°C dan kejadian hujan ekstrem (antara -55% hingga + 68%) di Kuala Selangor, berbanding dengan tahap masa lampau (1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993). Kenaikan paras laut untuk 2100 dijangka sebanyak 0.5 m. Perubahan iklim merupakan ancaman yang serius kepada sistem manusia dan ekosistem semula jadi di zon pesisir pantai Kuala Selangor. Peningkatan suhu permukaan dijangka mengakibatkan pengurangan pengeluaran hasil padi dan kelapa sawit. Keadaan iklim dan hidrologi yang ekstrem dijangka menyumbang kepada penyusutan tersebut. Kenaikan paras air laut akan meningkatkan kerentanan pembanjiran pantai di kawasan rendah dan seterusnya menjejaskan guna tanah yang sedia ada. Hampir 91% daripada komponen yang terdedah adalah kawasan pertanian dan hutan manakala yang selebihnya terdiri daripada kawasan pengangkutan, kediaman, infrastruktur, perniagaan, institusi awam dan industri (termasuk industri akuakultur). Selain itu, potensi perejahan air masin ke dalam akuifer pantai air bawah tanah semakin meningkat seiring dengan peningkatan paras air laut dan ini membawa implikasi terhadap sumber air bawah tanah yang bersih. Implikasi perubahan iklim terhadap zon pesisir pantai di Kuala Selangor dapat ditangani dengan menjalankan langkah adaptasi yang mengambilkira kedua-dua aspek permukaan dan sub-permukaan yang disepadukan ke dalam dasar perancangan zon pesisir pantai. Langkah adaptasi yang berkesan melibatkan pengumpulan maklumat saintifik, penilaian risiko, penentuan objektif adaptasi, penilaian adaptasi, pemilihan langkah adaptasi yang sesuai, perancangan, pelaksanaan dan pemantauan.Kata kunci: Perubahan iklim, kenaikan paras air laut, zon pesisir pantai, penilaian kerentanan, Kuala Selangor Abstract: Climate change is a variation in climate patterns due to natural and anthropogenic causes that affect human activity and natural ecosystems. Future projections (2025-2034 and 2041-2050) indicate increases in surface temperature of between 1.6 -2.3°C and extreme rainfall events (between -55% to +68%) in Kuala Selangor, compared to previous levels (1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993). Sea-level rise projected for 2100 is about 0.5 m. Climate change poses a serious threat to humans and natural ecosystems in the coastal zone of Kuala Selangor. The projected increase in surface temperature is expected to reduce the yield from paddy and oil palm plantations. Extreme climate and hydrological conditions are expected to contribute to this decline. Projected sea level rise will increase the susceptibility of low-lying areas to coastal inundation and compromise existing land use. Almost 91% of the exposed components are agricultural and forest areas while the rest comprises transport, residential, infrastructure, business, public ins...
