what is post settlement alluvium

Full Answer

A simple question can change the game

Howard Raiffa popularized the idea of the post-settlement settlement. When you get to an agreement, before you sign, ask the counterparty, “Is there any way that we could make this better for both of us?” You want to do so after an agreement has been reached. Why? Because the pressure is off, and you’re able to think more creatively.

Negotiation is about maximizing value

The essence of really good negotiation is maximizing value, right? Yet people don’t often go there. Because of this, they’re missing out on turning a good agreement into a great agreement.

Be mindful of your setup

The counterparty may think you’re trying to sneak something in or nickel and dime them, which is why the setup for your question is important. You need to make sure they know you’re comfortable with the agreement as it is. But you’re asking the question to see if there’s more value to be had for both parties.

How do floodplains store alluvium?

Floodplains store alluvium through lateral and vertical accretion, i.e. bedload deposits are being incorporated into the floodplain. Depositional episodes reflect the balance between the amount of sediments available and the capacity for it to be transported. Accordingly, the nature of LS on floodplains can be of different nature: (1) graded, when an excess of sediment and a deficit in transport capacity buries floodplains in continuous deposits, (2) cascading, when abundant sediment and limited transport capacity results in a series of frequent, but separated pockets, (3) punctuated, when limited sediment supply but efficient transport leads to deposition only in locally isolated pockets.

What is legacy sediment?

Legacy sediment (LS) is depositional bodies of sediment inherited from the increase of human activities since the Neolithic. These include a broad range of land use and land cover changes, such as agricultural clearance, lumbering and clearance of native vegetation, mining, road building, urbanization, as well as alterations brought to river systems in the form of dams and other engineering structures meant to control and regulate natural fluvial processes (erosion, deposition, lateral migration, meandering). The concept of LS is used in geomorphology, ecology, as well as in water quality and toxicological studies.

What are the most common contaminants that can absorb fine sediment?

The most common contaminants that can absorb fine sediment are trace metals, nutrients (e.g. nitrogen, phosphorus ), polynuclear aromatic hydrocarbons (PAHs), pathogens, polychlorinated biphenyls (PCBs), pesticides, volatile organic compounds (VOCs).
