The precise and depictive accumulation of a stream flow data is vital in illustrating the water resources of a region. Hydrometric gauging stations are locations containing tools and equipment used to calculate the flow of water in rivers, lakes, canals and streams. The aim of this assignment is to develop my understanding of stream power and specific stream power through my individual critical assessment of the class stream power exercise results. Stream power is a criterion that measures the amount of energy diffusion against river or stream bank. Specific stream power is the criterion that measures stream power per unit area of the river or stream channel. The stream power and specific stream power calculations were applied on the…show more content…
From Street view, the river is located close to the gauging station. Using the scale legend, the length of the river upstream and downstream from the gauging station is measured. And using an elevation profile, the height difference is obtained. Then the distance along the channel is divided by the height difference to determine the water surface slope. Calculating Stream power involves two elements: known constants and unknown variables. The known constants include gravitational constant of 9.8 m/s2 and the density of water at 1000 kg/m3. The unknown variables are discharge and water surface slope. By multiplying the both the constants and variables, the stream power is determined. Calculating specific stream power involves dividing the steam power by the channel width. Results The results of the bank full discharge and stream power are susceptible to the cross sections background and differ due to the various river motions and dynamics, particularly during flood events. Moreover, the shuttle radar map on an approximately 90 meter grid portraying the stream power of Irish rivers show vertical instability of the river channels from the longitudinal profile of the eastern Irish rivers. The bank full discharge generally increases from upstream to downstream, due to the where the majority of hydrometric gauging stations are situated which are in locations that inhabit distinct, constant and lone
