Even though this synthetic study shows the potential of remotely sensed surface soil moisture measurements for applications of watershed scale water resources management, future studies are necessary that focus on the use of real-time observational data.
The application of participatory watershed land-use management (PWLM), a systematic process with practical tools (e.g. scenario simulation, risk assessment), indicated that planned land-use conversion and projected climate change are likely to increase the intensity of flooding in the study area.
This can be corrected using a region merging algorithm or by preprocessing the image prior to the application of the watershed transform.
This task is similar to separating touching objects, which is a classical application of the watershed algorithm.
Figure 1 shows an example of a digitized mammogram before and after thresholding and application of the watershed algorithm (one image, one particular thresholding algorithm, Moments), and the same image thresholded by using Cumulus.
Computationally, this tessellation is computed through the application of the watershed method (Vincent and Soille, 1991) to the distance transform that is computed from binarized nuclear masks (Jan and Hsueh, 2000).
Prior to allocation of resources for BMP implementation, additional verification of the highest ranked watersheds must be done either through ground-truthing or the application of more sophisticated watershed transport models (Schweiger and others 2002).
Examples of the design criteria, efficiency calculation and application efficiency of these two measures, as well as case studies on the application of ecotechnological measures in watershed management in various regions, have been considered.
Application of lime to a watershed provides the advantage of increasing Ca availability and reducing or preventing mobilization of toxic Al, an outcome that is beneficial to both terrestrial and aquatic ecosystems.
