...Nowadays, the project team members work together to deal with the whole project. There are fifth designs phases arrange by Royal Institute of British Architects as follows: preparation, Design, pre-construction, construction and use. This essay is focus on using the integrated design method to build a 5-story office and utility. The integrated design can divide in three steps as drainage design, concrete design and foundation design. 2. Drainage Design: 1. Introduction Drainage design provided a system on managing storm water for specific area. The design must be effectively both on cost and conveyance to control the water flow, and protect water quality. This report focuses on the design procedure of drainage network based on information of catchment area, characteristics, slope, land use and flow rate and any other factors. The plan for future development would also be considered into the design. By examines the geology and hydrogeology of the study area, two drainage network was designed. This is a simple drainage design without considering the influence of soil type, different drainage system throughout this area, and water quality. The study area is in the Merseyside area of Britain. Modified and Rational Method would be used for estimating the peak discharge from a specific small area. By using the discharge value, the pipe size the network pattern would be decided. This report will give the information of study area, details of calculations and explanation and...

...season. Drains and cannels are stuck for several days and due to the drainage congestion Dhaka metropolitan area has experienced water logging for last couple of years. Even a little rain causes a serious problem for certain areas, so that parts of Dhaka are inundated for several days. It makes difficult to move for the passer by. Solution which comes out will help us from this topic. To find out inherent causes of water logging in Dhaka City, a field survey as a questionnaire survey, informal interviews from the people living in different parts of Dhaka City. PRESENT SITUATION The capital city of Bangladesh has become one of the populous Mega City in the world, in recent year’s sewerage and water logging has become as a common problem of the city like water pollution, traffic congestion, air and noise pollution, solid waste disposal, black smoke etc. Unplanned capital development activities and growth of habitation due to rapid population growth are causing encroachment on retention areas and natural drainage paths with little or no care of natural drainage system. Excessive rainfall, inadequate drainage sections, conventional drainage system with low capacity and gravity, natural siltation, absence of inlets and outlets, indefinite drainage outlets, lack of proper maintenance of existing drainage system, and over and above disposal of solid waste into the drains and drainage...

...GEO101L Earth Science Module 3 Lab: Soil Porosity and Permeability Soils are made up of particles of rock, along with the spaces between those particles. Physical characteristics of soil particles, such as size and shape, can influence how water moves through them. Aquifers are underground layers of rock that are capable of storing water. An aquifer is recharged when water filters through the soil levels above it. In this lab you will investigate the characteristics of known and unknown soil samples. The Lab Kit includes gravel, sand, and top soil samples, and you are to get a local sample from the soil at your home or a potted plant in your house. This lab will look at the porosity and permeability of these soil samples. Porosity is the basic measure of how much of its volume is open space. We will express porosity as the percentage of pore space in a material’s total volume. This lab will also look at permeability of these soil samples. Permeability is a measurement of how easily liquids flow through soil samples. We will calculate each sample’s drainage rate as well as percentage of water retention. Experiment 1: Methods to Measure Soil Porosity 1. Pour 100 mL of water into your 250ml plastic beaker and draw a line to indicate the water level in the beaker. Write 100 mL in the total volume column on your data sheet. Save this water since you can use it again. 2. Fill the 250ml plastic beaker with the first soil sample up to the line you drew (100ml)...

...Flood is defined as the over-flowing by water of the normal confines of a stream or other body of water, or the accumulation of water by drainage over areas that are not normally submerged (WMO, 1990). It is an unavoidable natural phenomenon occurring from time to time in all rivers and natural drainage systems which creates damages on properties, natural resources and people (Kumar and Santosh, 2015). In Ethiopia, a major river basin that has serious flood problems is the Awash River basin located in the Rift Valley. About 200,000-250,000 ha. is subject to flooding during high flows of the Awash River. The other rivers where significant floods occur are Wabi-Shebelle River in southeastern Ethiopia near the Somali border and Baro-Akobo/Sobat River in western...

In the process of proposing a conceivable solution, this paper will discuss the economic, political, and legal barriers of the solution, how they can be overcome, and why this solution will be successful. Flooding Issues in Houston, Texas Houston, Texas is home to over two million individuals, and is the fourth largest city within the United States of America. It is located in the Southeastern part of the state of Texas, and sits roughly 50 feet above sea level. Houston is known for its famous nickname of the Bayou City, as it is home to over 2,500 miles of manmade rivers. These manmade rivers (bayous) are the city of Houston’s way of containing and channeling rain water to the ocean. This alternative drainage system was a much needed installation because of the city’s position, as compared to the sea level (Bayou Preservation, 2012). Currently, Houston suffers from severe flooding issues (i.e. flash floods, urban floods, river and bayou floods), and depending upon the area of town, the probability of high and slow moving floodwaters increase. As the city’s population continues to rise, the roughly 650 square miles that encompass the city continues to become more crowded (urbanization). As such, the urban flooding issues continue to worsen, and the city of Houston continuously discusses how to combat, and eventually prevent the constant reoccurrences ("Floods and flash floods," 2012). Economic, Political, and Legal Implications of Houston's Flooding ...

...DRAINAGE he term drainage describes the river system of an area. Look at the physical map. You will notice that small streams flowing from different directions come together to form the main river, which ultimately drains into a large water body such as a lake or a sea or an ocean. The area drained by a single river system is called a drainage basin. A closer observation on a map will indicate that any elevated area, such as a mountain or an upland, separates two drainage basins. Such an upland is known as a water divide (Figure 3.1). Sr ea m B 3 T Sr ea m A W at er Di vi de subcontinent. Accordingly, the Indian rivers are divided into two major groups: • the Himalayan rivers; and • the Peninsular rivers. Apart from originating from the two major physiographic regions of India, the Himalayan and the Peninsular rivers are different from each other in many ways. Most of the Himalayan rivers are perennial. It means that they have water throughout the year. These rivers receive water from rain as well as from melted snow from the lofty mountains. The two major Himalayan rivers, the Indus and the Brahmaputra originate from the north of the mountain ranges. They have cut through the mountains making gorges. The Himalayan rivers have long courses from their source to the sea. They perform intensive erosional activity in their upper courses and carry huge loads of silt and sand. In the middle and the lower courses, these rivers form meanders, oxbow...

...pulmonary infiltrates possible pneumonia based on the result of chest x-ray. Also the presenting signs and symptom provided information that can link to pleural effusion evidenced of his signs and symptoms Pleural effusion Is an abnormal collection of fluid in the pleural space, it is not a disease but an indication of a disease (Lavie et al, 2014). Difference between transudate and exudate “A transudate effusion occurs primarily in noninflammatory conditions and is an accumulation of protein-poor, cell-poor fluid” (Lavie et al, 2014, p. 549). The fluid is leaking into the pleural space, the hydrostatic pressure is increased in the blood vessels, and the protein is low. “An exudate effusion results from increased capillary permeability characteristic of inflammatory reaction. It is most commonly associated with infections and malignancies” (Lavie et al., 2014, p. 549). The blood vessel is blocked or the inflammation result from fluid escaping into the tissues and cavities. Three common causes of pleural effusion “Pleural effusions can arise from a variety of disease states or medications including heart failure, bacterial pneumonia, and pulmonary embolism” (Saguil et al., 2014 p. 2). The reduction in lung volume, depression of the diaphragm and reduced chest wall compliance cause dyspnea, and occasionally pain or cough (Myatt, 2014). According to Donohue (2011), “infections, illnesses like rheumatoid arthritis, heart failure, blood clots in the lungs, liver cirrhosis and chest...

Landuse changes from rural to urban industrial areas cause local runoff impacts on receiving water flow, quality, and ecology. Apart from erosion and sedimentation problems associated with development, it has become increasingly apparent that stormwater runoff contributes to receiving waters a significant part of total loads of such pollutants as nutrients (including phosphorus and nitrogen), heavy metals, oil and grease, bacteria, etc. New, comprehensive, and integrated SWM strategies are now needed to be in line with the government’s drive to archive a sustainable developed nation status in the early 21st century. Such new strategies will incorporate interalia, runoff source control, management and delayed disposal on a catchment wide, proactive, and multi-functional basis. This should result in flood reduction, water quality improvement, and ecological enhancement in downstream receiving waters...

...Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs, and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within a watershed boundary.[1] Features of a watershed that agencies seek to manage include water supply, water quality, drainage, stormwater runoff, water rights, and the overall planning and utilization of watersheds. Landowners, land use agencies, stormwater management experts, environmental specialists, water use surveyors and communities all play an integral part in the management of a watershed.

These types of pollutants are considered nonpoint source pollution because the exact point where the pollutant originated cannot be identified. Such pollutants remain a major issue for water ways because the difficulty to control their sources hinders...
