Problem Statement versus Needs Assesment The determination of whether you write a problem statement or a needs assessment may hinge more on the funder’s priorities than your own passion for the project. Either way, the same information will be stated either as a reduction of what is currently a problem or an enhancement of a need to be added to a current situation. For example, let’s look at a fictitious rural community facing a particular environmental situation. The federal public land manager

each year (Fig.9, 10) shows how river transform each year at different reaches. Between each two years for different reaches, riverbank erosion and accretion happened consistently. Which indicate lots of riverbank eroded to make its way and lots of sediment deposition were going on during this time period.

the chicken wire. Then we can fill the chicken wire full of different irregular shaped rocks that fill the entire box of chicken wire. Once we have placed the gabion in its place the small spaces in between the rocks will then be filled with the sediment that is

The characteristics of a sandy shore at Pallarenda beach, Townsville, North Queensland. Introduction: The sandy shores of beaches can be considered as a very harsh environment to live in (Ted Klenk, 1999). Survival in such a habitat requires an organism to withstand strong wave and current action, tidal rise and fall, unstable substrate, heavy predation and wide variations in salinity and temperature (The Otter Island Project). Any organism found in this type of harsh environment is specialized

). Extreme storms can have greater effects, for example by completely destroying sand bars or other sediment deposits. All this implies that when there are strong waves estuary mouths open wider and when there are no waves the estuary mouths remain closed. River flow or fresh water in flow has a significant influence on estuaries (Levin and Boesch et

Introduction In this investigation, I will be investigating the changes along the long profile of a river. In order to do this, I will be collecting data and making observations at three different points along the river; the upper course, the middle course, and the lower course. The river which I will be conducting my observations would be on Bartley Water. Bartley Water is a river going through the New Forest which is located in the south of the UK, Hampshire. The source of the river begins from

Beach erosion is a serious issue today especially with human civilization building cities near the coast and disrupting the natural distribution of sediment deposition for our own convenience. Especially in southern California, beach erosion has some serious social, economic and environmental impacts on our society as a whole. Along with the rise of our sea levels due to global warming melting our polar ice caps, this erosion is having profound effects on coastal societies and has damaging effects

Marine Sediments are the particles of organic or inorganic matter that accumulates in a loose, unconsolidated form. After the continuous raining of sediments, the deep floors have varied from centimeters of thickness per year. When we think of sediment, we think have erosion of minerals that were once on land, remains of living organisms, and chemical reactions that associate with the ocean (terrigenous,biogenic, hydrogenous, and cosmogenic ). This process has helped determine the age of the seafloor

Cobequid-Chedabucto Fault system in Nova Scotia and beneath the infamous Bay of Fundy (Wade, 1996). This basin, in particular, is considered one of the ‘failed-rifts’ of the “half-graben” formed by the mid - late Triassic break up of Pangea. The Fundy Basin is a sediment-filled, proto-oceanic rift basin located along the margin of the Atlantic coast of

Geochemical proxy-based reconstruction widely utilizes the trace elemental and isotopic compositions of marine biogenic carbonates to interpret the past climatic and oceanographic conditions. However, such proxy-based reconstructions are often challenged by marine diagenesis as carbonates are highly susceptible to diagenesis, especially partial dissolution and secondary calcite recrystallization. Thus quantifying diagenetic effect is a prerequisite for development of any carbonate-based geochemical
