However, more fundamental research should be carried out to model the uncertainty involved in the underlying mechanisms related to the wastewater generation (rainfall profiles, household and industries pollutant discharges, assumed daily and weekly patterns, etc.).
Absolute humidity, dust and rainfall profiles, land-cover type, and population densities were independently associated with the location of epidemics.
In addition, absolute humidity and rainfall profiles predicted similar risks in geographic locations in north and west Africa, but a model including the former performed better for the entire continent than one including rainfall; for this reason, we kept absolute humidity as a variable.
An infiltration coefficient is introduced in the network architecture apart from antecedent rainfall, slope profile, groundwater level and shear strength of soil.
Brief site details of latitude, longitude, altitude, soil profile, rainfall and temperature regimes are also useful for selecting an appropriate range of provenances.
The model accounts for soil data profiles, rainfall, temperature, evaporation, runoff, streamflow, and more, to determine how much water is available for plants.
Another specially promising solution is related to the construction of phenomenological models that provide wastewater influent profiles in accordance with data about the catchment properties (number of inhabitant equivalents, sewer network, type of industries, rainfall and temperature profiles, etc.).
The calibrated version of the mosquito population sub-model allows for the calculation of temperature and rainfall dependent mosquito profiles for any year for which weather data are available.
Running these for hundreds of modelled years for alternative carbon dioxide concentrations, so as to build up statistical profiles of rainfall patterns, presents one of the biggest computational challenges ever tackled".
If rainfall is a problem, the profile promotes drainage – even designs in areas with monsoon rainfalls.
Model parameters were: Residue level, weed control, WSC, profile depth, and rainfall during fallow.
