“…Rainfall characteristics include rainfall depth, duration and intensity 316 (Kok et al, 2013;Speak et al, 2013;Stovin et al, 2013). In addition, the antecedent dry 317 weather period (ADWP) which separates rainfall events has also been identified as an 318 important factor influencing retention (Zhang & Guo, 2013).…”

“…Massive and uncontrolled urbanization generally leads to adverse impact to environment where it cause degradation of water quality and disturbance to hydrological cyle. High concentration of pollutant especially from non-point sources pollution will start to generate with the increased of impervious surface as more runoff are unable to infiltrate into the concrete surface [1][2][3][4][5]. In the past, urban waterways have been confined to narrow river corridors with the channels canalized and concrete and other synthetic materials forming the bed and banks of the river [6].…”

This paper aimed to analyze the pollutant loading composition of suspended solids, nitrogen and phosphorus in urban stormwater at Cameron Highlands which known as popular tourism, agriculture and function as reservoir water to generate electricity. Researchers found the urban stormwater quantity modeling has achieved sufficient accuracy benchmark. However, modeling stormwater runoff quality is relatively difficult and largely depends on catchment characteristics/land-uses. Model of Urban Stormwater Improvement Conceptualization (MUSIC) estimates pollutant transport from catchments and stormwater treatment through different application of Best Management Practices (BMPs). Result obtained from the observed and calculated data was compared with MUSIC's estimations under a similar scenario where no applications of BMPs. As a second scenario, series of treatment train is propose for each sub-catchments based on the suitability and verification on site that consists of constructed stormwater treatment BMPs (wetlands, bio-retention, on-site detention, sediment basin and gross pollutant traps). Implementation of BMPs reduce nearly 100% of gross pollutant, 65% - 83% TSS, 40% - 66% TP and 52% - 78% due to effectiveness of BMPs in treating the pollutant within different landuse. As a summary, MUSIC can conceptually determine the effectiveness of BMPs without giving a detailed design.

“…[2][3] Furthermore, climate change and variability have caused significant impacts on the hydrological cycle (flood and drought) as well as affecting the overall level of water availability in an urban city. [4][5][6][7] Flood frequency analysis is the most explicit method for determine the design flood which is very important part in the floodplain management, development and planning controls, and in the design of hydraulic structures. Usually, In Malaysia, a 100years ARI has been used for designing hydraulic structures.…”

The recent flood event occurred in 2014 had caused disaster in Perak and Sungai Perak is the main river of Perak which is a major natural drainage system within the state. The aim of this paper is to determine the expected discharge to return period downstream for Sg. Perak River Basin in Perak by using annual maximum flow data. Flood frequency analysis is a technique to assume the flow values corresponding to specific return periods or probabilities along the river at a different site. The method involves the observed annual maximum flow discharge data to calculate statistical information such as standard deviations, mean, sum, skewness and recurrence intervals. The flood frequency analysis for Sg. Perak River Basin was used Log Pearson Type-III probability distribution method. The annual maximum peak flow series data varying over period 1961 to 2016. The probability distribution function was applied to return periods (T) where T values are 2years, 5years, 10years, 25years, 50years, and 100years generally used in flood forecasting. Flood frequency curves are plotted after the choosing the best fits probability distribution for annual peak maximum data. The results for flood frequency analysis shows that Sg. Perak at Jambatan Iskandar much higher inflow discharge which is 3714.45m3/s at the 100years return period compare to Sg. Plus at Kg Lintang and Sg. Kinta at Weir G. With this, the 100years peak flow at Sg Perak river mouth is estimated to be in the range of 4,000 m3/s. Overall, the analysis relates the expected flow discharge to return period for all tributaries of Sg. Perak River Basin.
