Abstract
English: The collection and analysis of rainfall, stream flow and water quality data are described for an urban catchment used in model development. The data illustrates the existing hydrological conditions in the Palmier River Catchment, and forms the basis of simulations for model verification. Grab water quality samples were collected once a week at ten points for two years and flow-related grab samples collected flood water quality samples at a weir. The results show an increase in water quality constituents in the flow from the Pinetown CBD and a decrease from the residential areas. The data is then used to verify the models, which are found to perform satisfactorily.
Afrikaans: Die insameling en ontleding van reënval-, stroomvloei- en waterkwaliteitdata word bespreek. Die data illustreer die hidrologiese toestande in die Palmiet Rivier Opvanggebied, en vorm die basis vir simulasies vir modelstudies. Waterkwaliteitmonsters is een maal per week by 10 punte ingesamel vir twee jaar en 'n outomatiese monsternemer is gebruik om die kwaliteit van vloede te monster by 'n meetwal. Die resultate dui op 'n toename in besoedeling in die Pinetown sentrale sakekern en 'n afname in die woongebiede. Die resultate word dan gebruik om die modelle met bevredigend gevolge te toets.
