“…Based on field observation, the land use surrounding from km 21.82 to the end of simulation distance is dominated by agricultural activity mainly palm oil plantation. Therefore, simulated NH 3 -N is in line with study conducted by Zainudin et al (2010) which reported high concentration of NH 3 -N in the river contributed significantly by palm oil plantation. Higher concentration of NH 3 -N at the downstream of Sungai Langat during low flow seemed to consume more DO as part of nitrification.…”

This study attempts to assess the impact of various types of land use along Sungai Langat and describes hydrological change and water quality variation along this river. This study also determines water quality of Sungai Langat based on low flow dry period Q 100,7 using the application of QUAL2K. Dissolved oxygen (DO), pH, temperature and conductivity were measured in situ. Biochemical oxygen demand (BOD 5), ammonia nitrogen (NH 3-N) and total suspended solid (TSS) were analysed according to the standard methods (APHA). Water quality data was referred to National Water Quality Standards for Malaysia (NWQS) proposed by Malaysian Department of Environment (DOE) to estimate Sungai Langat water quality status. Four important water quality parameters namely DO, BOD 5, NH 3-N and TSS were simulated with QUAL2K version 2.07 for 83.67 km. As regard to individual parameter, DO classified this river into class III, BOD 5 in Class II, NH 3-N in Class IV and TSS in Class I. Based on QUAL2K simulation for low flow scenario, the results clearly demonstrates a gradually reduction of DO and BOD 5 whereas NH 3-N and TSS display opposite. Only NH 3-N was found significantly increase which cause low water quality class towards the downstream. Three parameters namely DO, BOD 5 and NH 3-N show effects of industrial which approximately located at the middle of river stretch. The TSS was contributed to the river system at the upstream and downstream of the river stretch which most likely from sand mining activity which located at Sungai Long, Cheras (near R5) and Sungai Semenyih (R11).

Problem statement:Mangrove forest is a component of wetlands that has been recognized as one of the most productive ecosystem in the tropic. Rapid development and other land uses in the mangrove areas over the years had negatively affected the ecological functions and its ecosystem. Study was carried out on river water quality at Sibuti Wildlife Sanctuary, Miri based on the physicochemical properties. The water quality status of river water at Sibuti Wildlife Sanctuary Mangrove Forest, Miri Sarawak is under category class II or good water quality status. All water quality parameters in this study are found to be in class I and II (good water quality) except for the BOD and DO which indicate fairer and moderate river water quality status.

“…Algunas de sus aplicaciones en el contexto de la evaluación de impactos y toma de decisiones frente a una gestión integral del recurso hídrico han sido desarrolladas. Zainudin et al, (50) realizaron la evaluación de la calidad del agua del río Tebrau para analizar la influencia de los vertimientos industriales y la implementación de diferentes estrategias de saneamiento como parte del plan de gestión de su cuenca. Pai et al, (51) realizó la evaluación del impacto del tratamiento de agua residual tratada con sistemas ecológicos de la ciudad de Taichung, Taiwan, utilizando la modelación del cuerpo hídrico antes y después de la implementación de los sistemas.…”

En este estudio se evaluó la implementación del reúso de agua residual municipal en agricultura, como una estrategia de prevención y control de la contaminación hídrica. Esta evaluación se desarrolló como un proceso metodológico de planificación del recurso hídrico superficial en las cuencas de los ríos Bolo y Frayle, principales fuentes hídricas de los municipios de Candelaria, Florida y Pradera ubicados en la cuenca Alta del río Cauca en el suroccidente colombiano. Dentro de los principales resultados del estudio se construyeron escenarios de planificación del recurso hídrico de manera participativa con los actores en las cuencas de estudio, que fueron evaluados con la herramienta de modelación QUAL2K. A través de la formulación de los escenarios y en un horizonte de 20 años, fue posible observar el mejoramiento de la calidad del agua de los ríos Bolo y Frayle bajo la implementación de escenarios de reutilización de las aguas residuales municipales. Evaluando esta estrategia, se observó que el Oxígeno Disuelto (OD) puede incrementarse en 5 mg/l y 2.5 mg/l en los ríos Bolo y Frayle respectivamente. Adicionalmente, con la implementación del reúso agrícola es posible obtener una reducción de la carga contaminante vertida del 94% y 62% para los ríos Bolo y Frayle respectivamente, en relación con la carga producida al final del horizonte de planificación (año 2036).
