Physical Geography Filed Work The aim of this field work was to study the long profile and its characteristics of the River Lym. The velocity then drops at the mouth where it tends to deposit its load The velocity then drops at the mouth where it tends to deposit its load This is the general long profile of the river where the gradient decreases as you go down the river. The source is highest point of the river basin which usually is a mountain. This is the general long profile of the river

often causing death. Pesticides and herbicides are toxins that are used to kill of unwanted animals and plants. These may be collected by rainwater runoff and carried into steams‚ rivers‚ lakes‚ and even into the ocean. More than 14 million Americans drink water contaminated by with pesticides. Nitrates‚ a pollutant often derived from fertilizer runoff‚ can cause methemoglobinemia in infants‚ a potentially lethal form of anemia that is also called blue baby syndrome.

Bottom sediment may be stirred up by such actions as waves or currents‚ bottom-feeding fish‚ people swimming‚ or wading‚ or storm runoff. Clear water may appear cleaner than turbid water‚ but it is not necessarily healthier. Water may be clear because it has too little dissolved oxygen‚ too much acidity or too many contaminants to support aquatic life. Water that is turbid from plankton

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

Name: Lee An Qi Class: 3H/7 Date: 2 June 2012 Urbanization is the process that leads to an increase in the number and proportion of people living in urban settlements such as cities or towns. It also refers to the increase in the size of land area occupied by urban settlements. To cope with urbanization within a drainage basin‚ urban development and deforestation are carried out‚ which affect flows to and within a river channel. Other factors like drainage density‚ climate‚ area of drainage

2.23 Nitrate-Nitrogen and Nitrite-Nitrogen in Drinking Water Nitrate may be naturally occurring‚ although its presence in drinking water is more often associated with contamination by excessive use of fertilizers (both inorganic and organic)‚ in addition to inappropriate farming practices and sewage. The high nitrate level in drinking water is also associated with the simultaneous presence of bacterial contamination (World Health Organisation‚ 1996). The primary health hazard from drinking water

Additionally‚ Most of the country is delta and flood plain‚ landforms formed by regular river floods. The amount of surface water makes them tough environments for populace‚ but at the same time they are also appealing because of the deep‚ constantly renewed silt soils that are extremely fertile‚ which support some of the highest agricultural densities of population in
