Point of Contention:
How to rate a watershed ? How to estimate the level of degradation in a watershed ? Which parameters can represent the status of a watershed ? Is it level of erosion/deforestation or change in climatic pattern or decay in water quality or land conversion ? Which will be the most important parameter to represent the status of the watershed or will it take more than one or two parameters to estimate the health of the watershed ?
Many questions are required to be answered before embargoing upon a watershed management plan.It is important to separate the needful watersheds from the already conserved catchments for optimal utilization of the available funds.But finding a full proof method is not very easy.
Do You Know ?
Spatial and Spectral Resolution:
Spatial Resolution in Geographical Information System is defined as the pixel spacing on the real earth surface or Ground Sample Distance(GSD) of the region captured in the image.
In general the Spatial Resolution can be defined as the measure of how closely lines can be resolved in an image.
Spectral Resolution in the other hand is the number of distinguishable spectrum or wavelengths which reproduce colour in a multi-spectral image
Summary : It is important to find a method/media for representation of Watershed Status for optimal distribution of fund of conservation.
