Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater

Theoretical background Upper course The source of the river is normally found in an area of high ground. The river usually flows through a steep V-shaped valley. Most of the erosion that occurs in the upper course is vertical and as the river bed is eroded lower the valley becomes steeper. The river is narrow with a shallow channel. As discharge is calculated by measuring the cross sectional area of the channel multiplied by the velocity‚ the discharge is small. The river is mainly slow flowing

Soil erosion: Soil erosion can be defined as the destruction of the top layer of the soil as a result of natural or human activities. Soil erosion refers to the carrying away of soil. Soil erosion is also serious type of

Temperature‚ moisture‚ soil type‚ microbial activity‚ oxygen concentration‚ sunlight‚ nitrification‚ and the amount of leaching all have an effect on the breakdown of pesticides in the soil (Extoxnet‚ 2000a). Rainfall patterns and the timing/intensity of irrigation in relation to high rainfall intensities will also influence herbicide movement in or from soil. Metolachlor is considered to be moderately persistent in different soil types (U.S. EPA‚ 1997)‚ and has an average field dissipation half-life
