Investigate process and/ or landform(s) along a stretch of a coast Hypothesis ‘The transport of sediment affects the morphology of Newhaven beach and Castlehead cliff’ This investigation will be exploring whether the movement of pebbles, shingle, shells and other materials found on the beach have impacted on the shape and structure of Newhaven beach and Castlehead Cliff. One of the key processes this investigation will focus on is that of long shore drift caused by strong prevailing winds, prevailing

Spring Lake Creek is located off of County road E in Sawyer County. The Spring Lake creek has a culvert that goes under County road E to Spring Lake. The culvert has the water flowing from Spring Lake into Spring Lake creek. With the road right by Spring Lake creek, one would think how much of the runoff from the road affect the water quality and invertebrate life. That is exactly the hypothesis a group from the Fresh Water Ecology class had come up with and wanted to experiment by testing two pools

result of turbidity currents [2]. A submarine fan is an accumulation of sediment that forms in a cone-like shape. The sediment is generally transported from a canyon into a main feeder channel to be deposited near the continental shelf. It is known that turbidity currents and other sediment gravity flows can form submarine fans. The main features of a submarine fan include a canyon, channels and levees. Canyons carry sediment from the shelf down to the fan structure. It was seen through imaging that

Introduction The 1960’s were considered the “golden age for dam construction” and contributed to thousands of dams being built across the United States. Dams are regualarly built to support recreational activities as well as hydroelectric power and water supply purposes but people recently have realized many of the negative impacts affiliated with them. Many are now 50 years old and due for relicensing which involves many tradeoffs for dam owners and public stakeholders to consider. Urbanization

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

e.g. shale, mudstone, any crystalline rock etc. and then erodes through that impermeable substrate the river could cease to exist. The substrate has a major effect on the river. The substrate can determine what type of river is formed, how much sediment the river is transporting, how much erosion is occurring in the river etc. The substrate is a very import factor when anyone is studying a

and mechanism of fluvial dynamics of anabranching Baghmati river system. In their study they have observed that anabranching phenomena of Baghmati river only occurs along middle river course. The authors suggested that inability to transport high sediment load due to gentle channel slope and dominance of aggradation processes are responsible for anabranching of Baghmati river. Luchi et al. (2007) investigated small alpine river to monitor morphodynamics of channel. Their study reveals that the longitudinal

estimated results, the geochemical tracers are extensively used in recent sediment fingerprinting studies (Franz et al. 2013; Grimes et al. 2007). Such as rare earth elements (REE; e.g., La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu), major elements (e.g., Fe, K, Na, Al, Ca and Mg) and trace elements (e.g., As, Ba, Co, Cr, Cs, Hf, Sc, Ta, Ti, Th and Zr), in both source soil and sediment samples, have been used in sediment fingerprinting studies (Horowitz et al. 2012; Hughes et al.

Soft rocks are very important geomaterials since they are heavily used in construction for example, buildings, road and dams but they sometimes seem to cause some problems due to their sedimentary properties like fast weathering and low strength. Weathering is a process in which rock break down or dissolve with the help of natural agents. Weathering and erosion are constantly changing the earth’s surface, so that has a big impact on construction and usage of soft rocks over time. Weathering can be

All the sponge parameters measured in our study in between the two discrete depth zones revealed a clear statistical difference and consistently higher values for the shallow location except from the sponge surface area (Median shallow,deep = 85, 152 cm2, respectively) and oscular number per sponge area (Median shallow,deep = 0.04, 024 cm2 respectively). Similar to our study of turbidity in the previous section the parameters given above for the deeper zone was higher for the sponges with lesser
