surface runoff happen when the rainfall intensity exceeds the soil’s infiltration capacity while saturation excess surface runoff is due to waterlogged on the soil where the soil no longer possess storage for any additional rainfall (Dunne & Black, 1970; Dunne, 1983). For the landscape which is prone to VSA hydrology, climatic variables used to determined the nature and extend of surface runoff (Cooper, 2010).
c. Urban Runoff
Urban runoff refers to any storm water and non-storm water runoff where it is a surface runoff of rainwater created by urbanization. Urban runoff usually contributes to the major source of urban flooding and urban water pollution. EPA define urban runoff as a storm water that come from city street and adjacent domestic or commercial properties which carries various kind of pollutant into the sewer system and receiving water.
Alteration on urban soil contain a large number of infrastructural components (e.g trenches that act as a

Different type of soil will have different infiltration rate. Silt and clay will generate more surface runoff as it has a slow infiltration rate compared to sand which have higher infiltration rate. The volume and rate of IEOF depends on the rate and soil hydraulic conductivity (Emmet, 1978). The hydraulic conductivity is one of the soil’s hydraulic properties that represents the measurement of the soil’s ability to transmit water through pore spaces or fractures where it depends on the structure of soil matrix, size of soil grain, fluid type and relative amount of soil fluid in the soil matrix. At a field scale, IEOF tends to increase down slopes as both surface and subsurface run-off from higher areas increases the hydraulic load, and hence the probability of overland flow in receiving areas (Nash, et. Al.,

In my hometown of Waterdown Ontario, there is rarely a minute when the main downtown area is not buzzing with people. In my opinion, the downtown area of Waterdown is alive and lively. Whether people are shopping in one of the variety of stores, grabbing a bite to eat at one of the numerous restaurants or cafés or just driving through, downtown is easily the focal point of town and continues to increase in chaos as Waterdown continues to grow and suburbanize. In Waterdown, the downtown core is where almost every shop and store is located. If you want to do anything from buy groceries to take a pottery class, you do so downtown.
Ray Bradbury’s “There Will Come Soft Rains,” tells the story of a self-regulating house that is all that is left of the world. Through the use of diction, the reader is able to understand the shifts in tone throughout the story. In the beginning of the story, we are introduced to the house. Bradbury uses terms such as “ruined city,” “radioactive glow,” and “rubble and ashes,” (Bradbury 1) effectively creating a dark and forlorn atmosphere. The author’s word choice creates an image in the reader’s mind of how desolate the house’s surroundings are, ultimately contributing to the somber tone.

It is with pleasure that I provide a letter of recommendation for Devincee Anderson. I have the opportunity of being a co-worker with him while he is currently employing at Division of Youth Services as a Youth Services Specialist-II. Devincee is extremely dedicated to the committed youths, detailed oriented, self-motivated, and deeply compassionate. Devincee is a natural leader and always meeting his deadlines. Devincee is an intelligent and motivated individual.
Re: Letter of Recommendation for Joshua Whiting To The RA Selection Committee: I write on behalf of Joshua Whiting’s application for a Resident Assistant position. I believe Josh to be an exemplary student-scholar as well as a person of tremendous character with significant leadership skills. I met Josh in my first semester of college in our biology class. We were both Biochemistry majors so we got to skip Biology 1 and therefore were both new to this new world of college but already in a group full of sophomores and students who had been in college for multiple semesters. Naturally we gravitated to each other due to this aspect we had in common.
‘Morning Rain’ by Hisaye Yamamoto and ‘Chang’ by Sigrid Nunez are short stories in the center of which remains a father – daughter relationship motif. It is not a very common topic in Asian American literature, and according to Wong and Santa Ana its representation in a literary texts is ‘a fairly recent phenomenon.’ Both Yamamoto and Nunez are creating the picture of the fathers through the eyes of their daughters. In these short stories, the children are discovering various parts of their dads’ identities by looking at their words and silences. The latter aspect of their behaviour becomes especially important, in understanding the true selves of the fathers, as they are an extremely quiet characters.
In the short story, “On the Rainy River” by Tim O’Brien, the author develops the idea that when an individual experiences a feeling of shame and humiliation, they often tend to neglect their desires and convictions to impress society. Tim, the narrator, starts off by describing his feeling of embarrassment, “I’ve had to live with it, feeling the shame”, before even elaborating on the cause of the feeling. Near the end of the story, he admits he does not run off and escape to Canada because it had nothing to do with his, “mortality...Embarrassment, that’s all it was”. The narrator experiences this feeling of intense shame and then he decides that he will be “a coward” and go to war. His personal desire is that he wishes to live a normal life and could never imagine himself charging at an enemy position nor ever taking aim at another human being.
How does a person’s response to and perspective of a crisis define him or her? In the event of a crisis, a person’s response and perspective of it can define him or her. In the novel, The Book Thief, written by Markus Zusak, and the short story, “On the Rainy River”, written by Tim O’Brien, the characters experience crisis all around them. Hans Hubermann in The Book Thief and Tim O’Brien in “On the Rainy River” have a hard time staying true to themselves in moments of crisis.
This leads to soil erosion. The water carries away the eroded soil and the eroded soil may be deposited in rivers. Rainwater flows quickly into rivers during heavy rain because there is no reservation of water by plant roots as well as water catchment areas. Due to oozing in the rivers, the water flow is slowed down and become blocked. Thus, water flow interior and causes flash floods in low areas.
2.8.2 Urbanization Urbanization led many areas becomes more modernized. Lowland areas have been reclaimed by taking land from the hills. There are also small rivers that filled up to be used as a building site. Activities such as these are a common factor of flooding. In the past, creeks and valleys turned into water flow, now the area has been covered with soil.
2.1 Urbanization and river water quality Due to movement of people from rural to urban areas, physical growth of the urban areas occurs, which ultimately leads to the urbanization, Over the past several years, river systems have always been extensively altered to meet various human demands, which led to them becoming the most intensively influenced ecosystems by human activities on the Earth (Nilsson, et al., 2005 )]. ‘’Among these human activities, the influence of urbanization on river systems was the most significant, and 60% of river systems were changed profoundly because of urbanization in the world’’ as cited by (Nilsson, et al., 2005 ) Recently, a number of studies have been done to understand the effects of urbanization on river water quality. The study manifested on Pearl River Delta Economic Zone is in China, that there is a positive correlation between the rapidity of urbanization and the pollution levels of urban river water.
The formation of the main reason is due to flood alluvial. When floods occur, especially in mountainous areas, the following
As the developed countries in Europe and the United States used to build on the backwardness of many underdeveloped countries, the "eco-city" of some developed countries today are also based on the pollution of more developing
