Hydrological simulation of these urban catchments requires rainfall time series at a very fine temporal resolution.
Hydrological analysis of such catchments requires high resolution precipitation and catchment information to properly represent catchment response.
Modelling the hydrological behaviour of suburban catchments requires an estimation of environmental features, including land use and hydrographic networks.
The issues are intricately linked, so that understanding trade-offs and making management decisions about coastal lakes and their catchments requires knowledge of the processes and interactions between all key components of the system.
The rainfall and API threshold of the four catchments, required to produce runoff in the reservoirs, are lowest for hillslopes with a short distance from the rock outcrops to the reservoirs and a low vegetation cover.
Information on upstream land use activities and land cover change, sediment yield within a catchment is required for controlling sediment accumulation in reservoirs.
Rural, remote, and isolated healthcare providers within the 2.74 million km2 catchment area require fixed wing, helicopter emergency medical services (HEMS), or ground ambulance for transport.
Understanding and modeling the variability of solute concentrations in catchment waters require the identification of the prevailing processes, determining their respective contribution to the observed transformation of substances, and the localization of "hot spots", that is, the most reactive areas of catchments.
The public transport available did not cover all areas within catchment population, requiring the CMW to use multiple modes of transport such as a van, car and motorbike, besides walking for miles.
Sound catchment management planning requires staff, resources, expertise and cash.
