particles by water erosion‚ losing great amounts of soil where the vegetation cover is thinnest. Plant roods bind the soil‚ while leaves protect it from the impact of heavy rain whilst layers of humus (leaf matter) helps to absorb rainfall and reduce runoff of soil into small rivulets. (small stream.) Any sort of slope will make water erosion more severe‚ as water attains more force thus dislodging plants and more soil. If the water is evenly seething and eroding the soil‚ this is known as “sheet erosion”The

Citizens of Sparksville Vernon Max Nissley ENV/100 Nov. 3‚ 2014 Lori Keller Hello citizens and council‚ Today I would like to address the choices we have available for creating new jobs for our city‚ due to the recent loss of a large company here. The three choices‚ we are considering‚ will each have an impact on our city‚ like roads and traffic‚ sewers‚ air and water pollution and the surrounding environment. When weighing these issues‚ along with the jobs and revenues that these companies can

Formula is one of the most frequently used urban hydrology methods in Malaysia. It gives satisfactory results for small catchments only • The formula is: C . y It . A Qy = 360 where‚ Qy = y year ARI peak flow (m3/s) C= dimensionless runoff coefficient yI t = y year ARI average rainfall intensity over time of concentration‚ tc ‚ (mm/hr) A= drainage area (ha) Or Q=CiA i = average rainfall intensity (in/hr)equals to tc A = catchment area ( acre) Q = Peak flow ( cusecs)

Should Atrazine be Banned? Atrazine is a herbicide used primarily on sugarcane‚ sorghum‚ and corn fields to prevent the growth of weeds. Atrazine has been a reliable herbicide for over 50 years. There are no alternatives that can compare to Atrazine. Atrazine is a herbicide classified in the triazine class that is used to prevent the growth of weeds in crop fields. A herbicide is a substance that is toxic to plants and is used to kill any unwanted vegetative growth. The National Corn

The Bradshaw model aims to show how different characteristics of a river change from the source to the mouth in a simplistic method that can easily be understood (greenfield geography‚ 2012). A geographical model is “an attempt to understand natures is high complexity. Therefore geographers try to develop simplified models of it” (Waugh‚ D. 2009). The model shows a series of triangles and each one represents a different fluvial characteristic. On the left is the source and on the right is the mouth

What is a Wetland ? Wetlands are habitats that fall somewhere on the environmental spectrum between land and water. Since wetlands lie at the interface of terrestrial and aquatic habitats‚ they possess a unique mixture of species‚ conditions‚ and interactions. As a result‚ wetlands are among our planet’s most diverse and varied habitats. Wetlands are defined by the soils‚ hydrology‚ and species that occur within them. Wetland soils‚ also known as hydric soils‚ are shaped by water. These soils

A ’flashy’ hydrograph has a short lag time‚ high peak discharge‚ and steep rising and falling limbs; a ’damped’ hydrograph is the opposite. Urban development is likely to make a river catchment more ’flashy’ and prone to flooding‚ because of rapid runoff from impermeable tarmac surfaces into streams. Hello MAtthew The shape of a hydrograph changes according to a number of controlling factors in the drainage basin. An example is the amount of VEGETATION / SOILS (INFILTRATION CAPACITY) LEVEL OF

On Friday February 03‚ 2012‚ we visited Don Egerico Mora Camacho and his wife Cecilia’s ranch. “They own 95 hectares of land‚ of which 5 hectares‚ in the lower part of the property‚ is in organic coffee and 90 hectares‚ which extend from their house up towards the Caraigres Mountains‚ is in cattle pastures.” We examined the land use capacity and made an evaluation the class of the soil. Honestly‚ this was a very interesting project for me because I had never done an experiment like such. Having

The Consequences of Water Pollution Annually‚ 90 million people add to the current population of 6.5 billion. At this rate the global population will reach approximately 8.5 billion by 2025 (http://dieoff.org/page120.htm). As the global population grows exponentially‚ so does the demand for natural resources. Of all these natural resources‚ water‚ is the most vital for survival and expansion. Human’s dependency on water will never go away‚ making it a key part to any civilizations future. It
