Long term seasonal and annual changes in rainfall duration and magnitude in Luvuvhu River Catchment, South Africa
… the long term seasonal and annual changes in rainfall duration and magnitude at Luvuvhu River Catchment (LRC). Rainfall in this catchment is highly variable and is characterised of extreme events which shift runoff process, affect the timing and magnitude of floods and drought, and alter …

Contaminant removal from impervious pavements and its relationship with raindrop impact energy, cumulative kinetic energy of rainfall events, and rainwater pH
… impact energy, cumulative kinetic energy of rainfall events, and rainwater fit were evaluated. A commercial urban area was chosen to perform simulated rainfall experiments. The runoff from these experiments was collected and analyzed for total suspended solids, volatile suspended solids, …

Carbonation of concrete bridge structures in three South African localities
… than Cape Peninsula bridges owing to shorter rainfall duration and higher temperature. In addition, the carbonation rates of both exposed and sheltered elements with similar concrete strength grades for bridges in Durban are very similar, i.e. exposure condition has little influence on …

Time characteristics of small watersheds in response to the probable maximum precipitation
… of Probable Maximum Precipitation (PMP) level rainfall events on the Loss Lake watershed in southcentral Missouri. Overland flow was simulated using kinematic wave routing and channel flow was simulated using dynamic wave routing.</p> <p>Lag time was defined as the time between the centroid of …

Evaluation of GSSHA for Simulating Sediment Concentrations in Steep Hawaiian Watersheds
… events were similar to calibration events in rainfall duration, accumulation, and peak intensity, indicating that one set of calibration parameters may not be sufficient for all storm events. Distinctively, however, it is shown that one set of calibration parameters may be sufficient for all …

The effect of catchment land use on sediment input to Swartvlei
… runoff and sediment loss in different rainfall conditions were determined. Rainfall, water flow, Secchi disc and sediment load data are reviewed and the apparent relationship between them noted. Water samples were collected at 32 different sample sites to determine sediment loads. …

Relating Land Use Factors to Phosphorus Runoff Concentrations within the Northrup Creek Watershed using GIS
… calculated within the study. Non-uniform storm rainfall duration and rates coupled with antecedent soil moisture content throughout the segments are very probable influences on the amount of phosphorus entering the creek at the various segments. A lower runoff residence time created by ponds and …
