Storm Water
Journal of Spatial Hydrology Spring Vol. 5, No. 1 Spatial Analysis of Urban Stormwater Quality
M. Ghafouri1 and C.E. Swain Abstract Urban stormwater non-point source pollutants are recognized as a major cause of receiving waters quality deterioration. To date most research has focused on specifying temporal variations of stormwater quality parameters which includes high uncertainties and also increases the risk of pollution control structures failure. Traditionally, the temporal variations of quality parameters in forms of either pollutograph or Event Mean Concentration (EMC) is obtained by sampling stormwater at the outlet of urban catchments for quality analysis in addition to measurement of flow rate over years. Spatial variations of the runoff quality are the key factor in non-point source pollution studies. This research investigates spatial variability of urban runoff quality parameters such as Total Phosphorous (TP), Total Nitrogen (TN), Suspended Solids (SS) and Biochemical Oxygen Demands (BOD) in relation to land use of urban catchments. In spatial analysis, stormwater will be sampled over the whole catchment area for a number of rainfall events during a year without any requirement to measure flow rate. This research showed comparable results for average pollutant concentrations with those of other urban catchments in Australia where traditional sampling method was used. The research outcomes will reliably estimate pollutants concentration for improved and efficient design of pollution control structures for each land use. KEY WORDS: Spatial analysis, temporal analysis, stormwater, Event Mean Concentration, geostatistics, pollutants Introduction Urbanisation, development and populating of an area create different pollutants, which are carried by stormwater to receiving waters, such as rivers and lakes, and deteriorate their quality and endanger their ecosystems. Urban stormwater, once was recognized as a major source of pollutants, is now considered as a

    2. About 450 cubic kilometres of wastewater are carried into coastal areas by rivers and streams every year. These pollution loads require an additional 6,000 cubic kilometres of freshwater to dilute the pollution. This amount equals to two-thirds of the world's total stable run-off.…

    The Lake Macquarie Stormwater Management Plan (SMP) was prepared in 1999 in response to a directive issued to all NSW Councils by the Environment Protection Authority. The SMP provides a framework for improved stormwater management and establishes opportunities to promote cooperative action by Council, stormwater managers and the community. It outlines planning and strategy measures such as requiring new developments to reduce the flow of stormwater off their sites. It sets out specific works that are…

    Think about all the bodies of water on our planet. Every river, lake, stream, and is essential to the way our world functions. Unfortunately, our society has done very little to preserve these water sources and as a result, our rivers, lakes, streams, and oceans are suffering from many forms of pollution. Every oil spill, discarded water bottle, and obstructive dam continually add to our already-polluted waters, and very little is being done to reverse this problem. The most prominent issue being studied today is storm water runoff. The collection of fine sediments, chemicals, and debris, are a serious pollution concern. Many solutions and technologies have already been developed, but the number one controversy that is holding us back is storm water regulations. Storm water regulations are the basic guidelines that all states follow when constructing storm drains and other runoff structures as well as controlling the pollutants that are discharged from water treatment plants (CLW,…

    Due to its specific location, Huntington Beach can have many possible sources of contamination, including the offshore sewage, urban runoff, and bird feces from the Talbert Coastal Marsh (Choi et al., 2003). Huntington Beach is located in the heavily urbanized Santa Ana watershed and there are some factors that are behind the importance when considering BMPs for this area. In arid regions, such as Southern California, stormwater in particular effects coastal water quality because a large percentage of the water runoff and pollution flows into the ocean in just a few storms in the winter (Ho Ahn et al., 2005). Many urbanized watersheds, Santa Ana included, have a stormwater flow that is controlled by municipal infrastructure that is used to minimize flood potential and maximize water reclamation. This, then, results in the discharge into coastal waters for days even after a rain event, causing a potential for human exposure to pathogens in beaches (Ho Ahn et al. 2005).…

    The water from the creeks and water bodies around Brisbane will be unsafe to drink as the water is polluted and results will not be in the recommended requirements for safe drinking. It is expected that Bulimba Creek is polluted because it is a large water way and therefore it is hard for one committee to maintain the watery way’s health while respecting its biodiversity (BulimbaCreek.org, 2015). It is expected that Waterloo Bay is undrinkable because it is a salt water body (Health-e-waterways.org, 2012). It is expected that Phillips Creek is undrinkable because it is located in an industrial area and surrounded by many shops and petrol stations, which can lead to exposure of chemicals which can pollute the water (BulimbaCreek.org, n.d.).…

    Prior to the Riverwatch Trip I was skeptical as to how much the wastewater treatment facilities in Calgary contributed to the wellness and overall health of the Bow River. However, through various tests before and after the treated water has been combined with the river water, I concluded that the wastewater facilities are well worth the tax dollars. Calgary is a large city of over 1 million people and as such produces an abundance of waste which should cause nitrate levels in the water to go up as well an increase in turbidity; not to mention many other negative affects to the water and the organisms dependant on the river. Nonetheless, nitrate and turbidity levels downstream and upstream of the treatment plant remain in the same range. Maintaining nitrate levels is…

    Concerns that I have for our watershed is that people would be people pollute the storm drains that then could cause an algae bloom. I found evidence to support this claim from coastal-watershed.org/threats-to-watershed-health/ where it states “Urban Runoff or ‘storm drain pollution’ is one of the leading causes of water pollution in this country. Urban areas contain up to 90 percent hard surfaces such as rooftops and pavement where water collects and quickly runs off. Urban Runoff is difficult to prevent because it is nonpoint pollution. That is, instead of originating from a single-point source, such as a factory or sewage treatment plant, the sources of urban runoff are spread throughout an urban area. Such sources include yards, sidewalks,…

    Pollution can be defined as a harm to the environment which can cause a lot of bad consequences to human health, living resources and ecological. Thus, pollutants can be gain from many sources and can take many forms. The pollutants can contaminate land, water or air. In order to identify types of pollutants and the level of pollution, the first step that has to be taken is the collection of a representative sample. Sampling techniques varies depends on the type of sample. Water sampling is important in order to detect the pollution of organisms, hydrocarbon, metals or others pollutants in water. Sampling of most wastewaters and contaminated water is difficult due to their highly variable nature. To obtain an accurate assessment, samples have to be taken over a period of time period, over different sections of the water way and at different depths.…

    Stormwater drainage is a system intended to collect rain water or water runoff and allows it to flow to the drainage pipe or canal to prevent flooding. It is widely used in every roads and highways through the gutter and enables the water runoff or rain water to flow to the stormwater drainage inlet. Every single house has its own drainage pipe that connect to the stormwater drainage system to collect grey water so as not to easily full their own septic tanks which collects the black water from every house. Stormwater drainage system is very essential in every community, because it helps to control flooding which will prevent accidents especially when rainy season or a huge storm comes.…
