Results of the simulation indicate that the temporal stability of erosion rates determined from CRN concentrations in sediment decreases with increased ratios of landsliding to bedrock weathering rates within a given catchment area, and that as the frequency of landsliding increases, larger catchment areas must be sampled in order to accurately evaluate long-term erosion rates.
However, a conclusive threshold on the area of the catchment which must be cleared in semi-arid environments before substantial change in runoff is realized has not yet been determined.
The solution can only be found at a global scale (all the catchment area must be taken in account: land plots and their spatial configuration), and by taking a long-term approach.
For a well functioning district health system – of which such a hospital forms a key component – the catchment population must be known.
For Programme Managers, catchment areas per CHW must be assessed to combine 2 factors moving at times in different directions: 1) geographic access and 2) size of population covered, to optimize utilisation of CHWs.
In any case, this finding suggests that national and local planners must be aware of CHW catchment areas and ensure that any variability does not result in variable access to treatment.
Since uplift has been regional, there is no evidence of anomalous neotectonics, and climatic history must be comparable to the adjacent catchments (both of which have staircase sequences) a catchment-specific mechanism is required.
The origin of these estrogenic compounds must be located in the direct catchment of "Shaft".
Because fractional franchising works through the existing private sector, a base level of activity in the private sector must be present, and these providers must be actively serving catchment areas where low- and middle-income clients live or work.
"Land management, from the upper reaches of catchments to the lowlands, has been part of the problem and must be part of the solution to managing uncontrolled flooding," said Martin Harper, the RSPB's conservation director.
For surveillance to effectively provide early warning for epidemic transmission, it must be active, laboratory based, and comprehensive in its coverage of the spectrum of clinical illness, the catchment area, and the factors that influence transmission dynamics.
