## Abstract Current and historical data show that nitrogen concentrations and flux in the Mississippi River Basin have increased significantly during the past 100 years. Most of the increase observed in the lower Mississippi River has occurred since the early 1970s and is due almost entirely to an

. A study of long-term slope stability in the Sydney Basin, Australia. Eng. Geol.; 10: 1--12.
A study of slope characteristics in part of the Sydney Basin indicates that landslide occurrence and long-term slope stability are both governed by the residual shear strength of the clay soils which weather from the Triassic shales of this area. Both the present distribution of landslides and the form of the slopes themselves lend support to this conclusion.
It is found that on the Wianamatta shales forming the Razorback Range southwest of Sydney, landslides may only occur on slopes whose inclination exceeds 11 Β° . The average value of ~'r measured in direct shear was found to be 22 Β°. Values of ~r were,found to be very small hut positive.

In the 1970s, The Netherlands were confronted with eight large-scale hijackings, in which a total of nearly 500 persons were held hostage. In 198S, the long-term aftereffects (up to 9 years) of these hostage takings were studied. Approximately one-third of the ex-hostages studied were found to suffe
## Abstract Relationships between slope form and stream magnitude, drainage area and stream gradient are investigated in a small upland catchment experiencing active stream incision. Profiles selected on a stratified random basis provide data on five slope form variables. The observed relationships
