People sometimes get caught up in the elegance of the expression of others and use those ideas and words without credit. "That person said it so well. That's exactly what I should say". The problem comes not when the ideas of others are used but when the material used is not credited or material is quoted and not acknowledged. Documented plagiarism from the literature, from another student, or falsification of data will result in a zero for the final paper. Use of another's ideas with credit is not plagiarism. Therefore, it is important to correctly and copiously cite your sources.
Examples of quotes from real papers followed by quotes from journal articles are presented below. The student papers have not been referenced to preserve the anonymity of the student writer.

Detection of Casing Leaks
Casing leaks can be detected by inspecting the water level data. A casing leak is recognized if the water level appears to be unusually high or low as compared to other monitoring wells in the vicinity. If the leak is large and in a zone of much higher permeability than at the well intake, the well may act hydraulically as if it were completed in the zone where the leak is situated. The response of the well to hydraulic transients such as those induced by water table fluctuations, nearby drilling, or pumping from a nearby well will then reflect conditions in the formation near the leak. Also in such cases, response tests may reflect the permeability around the leak rather than around the intake (Herzog et al., 1988).
The water quality in a monitoring well may be strongly affected by casing
leaks if the flow is inward through the casing and down to the well intake
(Meiri, 1989). "
The magnitude of leakage flow is proportional to the head difference in the formation between the level of the casing leak and the monitoring well intake. Leakage effects are therefore most likely to be important if the casing passes through low-permeability zones, because such zones tend to have large differences of hydraulic head across them.
Detection of Casing Leaks
Casing leakage in a recharge setting is illustrated schematically in
Figure 1. The downward hydraulic gradient in the formation results in downward
flow through the casing, and the water level in the casing is higher than
the undisturbed head in the formation around the intake. If the cumulative
downward flow is large enough and a vertical chemical gradient exists it
will lead to changes of the water quality in and around the monitoring
well intake. In a discharge setting the flow directions is upward. The
water quality in the monitoring well is then not affected, but the water
level in the casing may be lower than the undisturbed head in the formation
around the intake."
Even the longitudinal profile reflects the effects of lithology on ground
water sapping processes. The longitudinal profile of theater-headed canyons
reflects the interaction between surface runoff, sapping, and depositional
processes. The profile is divided into two zones (Fig. 7). The upper region
is characterized by steep headwalls (120-150 m in height), and is generally
concave upward. Below the headwall, sapping along the contact between the
Navajo Sandstone and the Keyenta Formation has resulted in a profile that
tends to approximate the dip of the beds and is usually fairly straight
(Laity and Malin, 1985)."
The longitudinal profile of theater-headed canyons reflects the interaction
of surface runoff, sapping, and depositional processes. It is characterized
by the presence of steep headwalls (120-150 m in height) that divide the
profile into upper and lower zones (Fig. 3). In the upper reaches, surface
runoff cuts a profile that is more or less concave upward. Below the headwall,
sapping along the contact between the Navajo Sandstone and the Kayenta
Formation has resulted in a profile that tends to approximate the dip of
the beds and is usually fairly straight. This form is subsequently modified
by incision resulting from overland flow and by episodes of deposition
(Gregory, 1938; Cooley, 1962; Euler and others, 1979)"
"Of various watershed-scale disturbances, floods have received perhaps the most attention from geomorphologists. Indeed, the literature contains many examples and descriptions of how floods have modified stream channels (see Baker et al., 1988, or Beven and Carling, 1989). From this work, it seems clear that the largest floods (meaning "large" in terms of discharge per unit drainage area or in relation to the mean annual flood) occur in small drainage basins in arid and semiarid regions (Costa, 1987). It is less clear why some floods are more effective in modifying stream channels than others. Wolman and Gerson (1978) suggest that geomorphic effectiveness was determined largely by climate, but topography, lithology, and vegetation are important as well. They further suggested that geomorphic effectiveness could be evaluated in terms of the length of time required for a landform to recover its prior condition. What constitutes "recover" in the case of rivers remains somewhat ambiguous, but examples might include the reconstruction of floodplains (Hack and Goodlett, 1960; Schumm and Lichty, 1963) or the restoration of preflood channel width (Osterkamp and Costa, 1987), hydraulic geometry (Lisle, 1982), bed elevation (Kelsey, 1980), and sediment loads (Newson, 1980). When viewed in t his context, recovery essentially involves the re-establishment of a quasi-equilibrium channel in response to changes in discharge and sediment load."
"Details of the Lawn Lake flood are described thoroughly by Jarrett
and Costa (1986) and Blair (1987). A peak discharge estimated by the slope-area
method of about 500 m3/s occurred just downstream of Lawn Lake.
Above the Roaring River alluvial fan, the peak discharge of the flood was
estimated to be 340 m3/s; Jarrett and Costa (1986) suggested
this was about 300 times the 500-yr flood for Roaring River. The peak discharge
on Fall River near the outlet of Horseshoe Park (Fig. 1) was estimated
to be 200 m3/s, which is about eight times the 500-year for
this stream (Table 1). Two aspects of the Lawn Lake flood are important
in the context of this study."
Another problem in science today is data falsification. Both plagiarism
and data falsification are breaches of academic conduct which can have
serious repercussions. Society and the University should and do take
such conduct very seriously. A real letter from the U.S. Geological
Survey will be distributed in class as an example of the consequences.
Do you know of examples of cases where such ethical issues have come up?
