    three subsystems: • Paved areas (walkways and roads) • Buildings (rooftops) • Vegetation (lawns, ovals, flora) The manner in which the subsystems relate to each other is governed by the direction of water flow and surface properties of the subsystem. Generally, rainfall onto hard surfaces (buildings and paved areas) either results in runoff into gutters and vegetation or water detention; the opposite is not true, as vegetative areas are generally much more permeable, meaning more water detention.

    Estimating Bifenthrin Concentration in Surface water in Urban Sacramento. Introduction Pyrethroid insecticides have replaced organophosphates (OP) insecticides, such as, diazinon and chlorpyrifos for structural pest control and landscape maintenance in most urban environments in the United States in recent times. Pyrethroids are manufactured derivatives of pyrethrins, which are natural insecticides that are produced by certain species of chrysanthemum. These insecticides are neurotoxins and focus

    infrastructure(EPA,2013; IPCC, 2007). Gray infrastructure drainage features do not treat runoff, but instead simply move water from areas of human activity to local waterways. In urbanized coastal environments runoff collects and carries various pollutants to surface waters, including bays and estuaries, through MS4 systems. Thus increased precipitation will result in higher levels of untreated runoff entering waterways. Of more immediate concern is the fact that present infrastructure features are simply not

    they might be in jeopardy of losing. Surface mining began to replace traditional underground mining around WWII (Bozzi 116). Rather than digging into the mountain to extract the coal, strip mining involves removing the overlying soil and rock that covers the coal deposits (Lutz 1). It seemed appealing at first because the previous known dangers of black-lung disease and cave-ins were now limited with the surface mining method (Bozzi 116). However, surface mining came with it’s own problems, a lot

    Chapter 9 on biodiversity and the ecosystem was interesting, especially the section on forests. Living in a forest area and being surrounded by them my entire life it was really interesting to learn so much more about forests. Even when humans think they are being responsible, they can still cause great harm. The building of roads to farm trees for instance, can cause damage to a forest because it increases erosion, water runoff, and it can harm the diversity of an ecosystem (Miller & Spoolman, 2010)

    Although there are many groups interested in an issue such as this, the large majority fall under 5 categories. The first and most obvious category is the farmers, as they are the ones that will be directly affected by any sort of legislation regarding agricultural runoff. This group’s interests would mostly lie in keeping their annual yield stable, as it is how they earn their living. Due to this, the farmers’ position could possibly be against the stricter law, because it has the potential to

    To investigate the relationship between surface area : volume ratio and heat loss. INTRODUCTION: The aim of this experiment is to investigate and find the relationship between heat loss (of water) and surface area to volume ratio of animals. To investigate this, we are going to use three flasks of different volume (as the equivalent the animals) and thus different surface areas filled with water. BACKGROUND: Surface Area : Volume Ratios We will be using the following formula for calculating
