Non-point source Pollution Homework #1
Diffuse pollution is the release of potential pollutants from a range of activities that individually many have no effect on the water environment, but at the scale of a catchment
This paper aims at comparing the cost effectiveness of the two mainly used wastewater system, that is the combined sewer system and the separate sewer system, based on the analysis of simulations. The problem which of the 2 systems is better was heavily d
CIVE 4179 Homework #2 Solution Problem #1 1) As the mass of the pollutant (concentration) increase and weight of 1 Litre of solution > 106mg then, the values of ppm and mg/L diverge. They are close at low concentrations. Problem #2 Total mass of : Molecul

Problem 1. Pollutant concentrations in water are frequently reported in units of ppm or mg/l. What is the difference between ppm and mg/l? When are these units of concentration essentially equivalent? Problem
A delivery ratio
A delivery ratio (DR), defined in Chapter 3, relates the sediment yield to the upland erosion: Y = DR (A) (5.1) where Y is the sediment yield, DR the delivery ratio (dimensionless), and A the gross erosion in the watershed.

HOMEWORK ASSIGNMENT 1 DIFFUSE POLLUTION IT'S ALL AROUND US!
Due: Jan 13, 2012
Diffuse pollution by definition is all around us. This assignment is to help you identify diffuse pollution sources, specific pollutants associated with them, and co
