U-Solve is the only software program available in South Africa that will calculate certified whole-window U-values and SHGC values based on Wispecos range of aluminium extrusions.

PVgis is the ideal free online tool to estimate the solar electricity production of a photovoltaic PV system. Flood Design Software. Up to 10 cash back The paper provided ways to estimate short-duration design storms at the locations where no rain gauge is installed in South Africa.

Pdf Design Rainfall Estimation In South Africa Using Bartlett Lewis Rectangular Pulse Rainfall Models Flood Design Software. The Rainfall Intensity can simply be taken as 0014lsm² 50mmhr for small paved areas of up to 4000m² according to BS EN 16933-2. Created by Ping-Ping Xie this replaces RFE 10 the previous rainfall estimation algorithm that was operational from 1995 through 2000 Herman et al 1997.

Choose the design storm frequency and use the. How accurately do I have to specify the coordinates when I estimate a design rainfall. PVGIS is an online free solar photovoltaic energy calculator for stand alone or connected to the grid PV systems and plants in Europe Africa America and Asia.

Climate Prediction Center CPC Rainfall Estimator RFE for Africa. They are available with. To design flood estimation in South Africa are highlighted by Alexander 2002 Smithers and Schulze 2003 and Görgens 2007.

Standard techniques for design flood estimation have been. 1960s and early 1970s as summarised in HRU 1972 and are in. All the design rainfall outputs are for sliding durations eg.

The estimation of design values at ungauged sites Smithers and Schulze 2003. Royal HaskoningDHV South Africa. Development and evaluation of techniques for estimating short duration design rainfall in South Africa.

The design rainfall intensity is the intensity of a constant intensity design storm having the specified design return period and duration equal to the time of concentration for the drainage area. The rainfall intensity can be determined using the following steps. This contrasts with the raw data which are mostly for fixed durations eg.

Design rainfall and flood estimation in South Africa. Rain gauges radar etc.

They showed that for a 24-h storm the mean of daily annual maximum series AMS can be more or less precisely estimated as a function of mean annual precipitation MAP. Daily values read at 0900UTC. Solar electricity generator simulation and solar radiations maps.

Analysis of regional variations in SPI over Southern Africa using Climate Research Unit CRU data from the University of East Anglia Water quality situation assessment model a developing model for simulating daily water quality variables from monthly simulations obtained from a rainfall-runoff model or a systems yield model. Design Flood Estimation in South Africa. This value corresponds roughly to a design storm of 5 minutes duration and a return period of 1 year.

Most of the methods used for design flood estimation in South Africa were developed in the late. Design storms and long term synthetic rainfall records derived from historic rainfall data. Irrespective of whether a single site or regional approach is followed the design rainfall depth to be used in design flood estimation especially in the deterministic methods must be based on the critical storm duration or time of concentration T C of a catchment.

You can also use these formulas along with the Rational Method equation to calculate the design storm water runoff rate from values for the drainage area and the rational method runoff coefficient. Parameters Needed to Calculate Design Rainfall Intensity. Download full-text PDF.

In South Africa numerous regional- and national-scale studies have focused on design rainfall estimations for daily and sub-daily durations. Once values for design return period and duration are available the design rainfall intensity can be determined. Relatively few recording raingauges with long reliable records are available in South Africa for the estimation of short duration 24 h design rainfallsHence approaches to estimating short duration design rainfalls have been developed for South Africa which are based on daily rainfall data measured by standard non-recording raingauges at fixed 24 h periods.

The most recent South African method for design rainfall estimation for short and long durations was developed by Smithers and Schulze 2003 which provides estimates for return periods ranging from 2. Acording to Van der Spuy and Rademeyer 2010 there is still no universally applicable method for design flood estimation in South Africa. An 8-day estimate is for 192 consecutive hours and may start at any hour of day.
