Problem 5-52. Plot of C/N ratios versus d13C for various sediment samples from the Columbia river and continental margin. Two mixing lines are drawn, one between the reservoirs marine plankton and soil organic matter and the other between the reservoirs marine plankton and vascular plant material. Percent of these end members in each sample is estimated from these mixing lines. Note the marked correlation between sediment type and end member reservoirs. The end member reservoirs are taken from Figure 5-26 in the text. Fig5-52.jpg (318832 bytes)

Problem 6-44a. Plot of the natural log of the activity versus depth for Nainital lake. The straight-line relationship indicates a constant sedimentation rate. Figure 6-44a.jpg (77233 bytes)   Problem 6-44b. Plot of the natural log of the activity versus depth for Sattal lake. The straight-line relationship indicates a constant sedimentation rate. Figure 6-44b.jpg (79616 bytes)
Problem 6-54. Graphical solution for problem 6-54. G = groundwater, F = runoff from fields, R = runoff from feedlot, and W = contaminated well water. Fig6-54.jpg (227464 bytes)      
Chapter 7 Problems
Problem 7-52a. Plot of Cads versus Csoln. Figure 7-52a.jpg (16094 bytes)   Problem 7-52b. Plot of log Cads versus log Csoln. The slope of the line gives the values for n and the y-intercept gives the value for K. Figure 7-52b.jpg (19528 bytes)
Problem 7-54a. Plot of Cads versus Csoln. The shape of the curve, particularly the flattening of the curve at high concentrations, suggests that the data fit a Langmuir isotherm. Figure 7-54a.jpg (15991 bytes)   Problem 7-54b. Plot of 1/Cads versus 1/Csoln. The slope of the line = 1/KQo and the y-intercept = 1/Qo. Figure 7-54b.jpg (16993 bytes)
Chapter 8 Problems

Chapter 9 Problems
Problem 9-77. Piper diagram for Colorado and Nile river waters.   Problem 9-78. Piper diagram showing mixing between a tributary and a river.
Problem 9-106a. Plot of Cl/Br ratio versus distance of groundwater sample from the petrol station. The low Cl/Br ratios are indicative of groundwater samples  contaminated by ethylene dibromide. The higher Cl/Br ratios are indicative of uncontaminated groundwater. Figure 9-106a.jpg (17041 bytes)   Problem 9-106b. Plot of Br- versus Cl-. The data form a linear array which suggests that the groundwater chemistry can be explained by simple mixing between uncontaminated groundwater and contaminated groundwater from the petrol station. Figure 9-106b.jpg (20814 bytes)
