Terracing is one of the oldest means of saving soil and water. The objective of this paper is to provide information on the different types of terraces and their functioning, and to describe advantages and disadvantages of terraces regarding their efficacy to stop or reduce soil erosion. Existing literature and information shows that terraces can considerably reduce soil loss due to water erosi...

The principles are discussed of bench terracing and deep tined tillage, on the level contour, appliedto selected shallow soils on steep slopes of the Ifafa area on the Natal south coast. Results from 36 month old timber (Eucalyptus grandis) and [4 month old sugarcane (N16) grown on bench terraces are reported and compared with current practices. The implications of this site-specific technique ...

terracing is an operator that is applied to potential field data to produce regions of constant field amplitude that are separated by sharp boundaries. magnetic data are usually transformed into pseudo-gravity data (baranov, 1957) prior to the application of terracing. the objective of terracing is ‘to recast potential field maps into a geologic map like format’ (cordell and mccafferty 1989). t...

We present two new methods for approximating elevation data from contours to a grid. The first repeatedly interpolates new contour lines between the original ones. The second starts with any interpolated or approximated surface, determines its gradient lines, and does a Catmull-Rom spline interpolation along them to improve the elevations. We compare the new methods to a more classical thin-pla...

In semi-arid and arid terrestrial ecosystems, terracing vegetation may improve soil conditions enhance habitats. Considerable recent works have focused on evaluating how affect individual ecosystem function, but none of these evaluations included multifunctionality (SEMF), which has a positive significance for optimizing management. Based the survey data six different combinations in Chinese Lo...

one of the main goals of interpretation of gravity data is to detect location and edges of the anomalies. edge detection of gravity anomalies is carried out by different methods. terracing of the data is one of the approaches that help the interpreter to achieve appropriate results of edge detection. this goal becomes a complex task when the gravity anomalies have smooth borders due to gradual ...
