Suitability for Water Harvesting : Macro - Catchment system Areas Suitable for agricultural use

The modeling of suitability for macro-catchments is more complicated than for micro-catchments, because the run-off is generated outside the pixel to be evaluated, and is a largely unknown quantity. The evaluation of suitability for macro-catchments requires the separate evaluation of suitability for a 'catchment' area and for a 'use' area. The criteria for the 'catchment' and 'use' areas are different: - for the catchment area, strongly sloping land with soils that are shallow, rocky, or have poor infiltration capacity is preferable; - for the use area, level or gently undulating land with deep soils and no other limitations to agricultural use is preferable -...

Description

The modeling of suitability for macro-catchments is more complicated than for micro-catchments, because the run-off is generated outside the pixel to be evaluated, and is a largely unknown quantity. The evaluation of suitability for macro-catchments requires the separate evaluation of suitability for a 'catchment' area and for a 'use' area. The criteria for the 'catchment' and 'use' areas are different: - for the catchment area, strongly sloping land with soils that are shallow, rocky, or have poor infiltration capacity is preferable; - for the use area, level or gently undulating land with deep soils and no other limitations to agricultural use is preferable - in addition, land suitable for use as a catchment, must be within a certain distance of land suitable for agricultural use. The problem of identifying, in a GIS environment, land with these contrasting requirements is then reduced to a separate assessment of suitability for catchment and agricultural purposes, followed by an assessment of the constraint imposed by distance between these two different environments. In the evaluation of suitability for agricultural use, precipitation, slope, soil and land use criteria are considered.
