MMA at the 2017 Second European HEC Software Conference, London

MMA was at the second European Conference on HEC Software in London in July 2017 following on from the highly successful first HEC European Workshop in October 2016 when Tony Green presented for a session on sediment modelling.

The Workshops have been lead by key HEC developers who travelled from the US to impart valuable insights on the continuing development of features of HECRAS 5 both 1D and 2D models.

Heavy Rainfall in Phnom Penh -Update

Allthough it was been a very dry rainy season in 2015, storms on Friday 31 and Saturday 1 August 2015 caused widespread flooding of roads and suburbs of Phnom Penh.  Update - in July 2016 it looked like potential evapotranspiration would be greater than the rainfall during the month until 25 July when 80mm fell in little more than an hour with peak intensity over 250mm/hr. Not surprisingly surface water drains were surcharged even though improvements had been made over the previous year.

Weather Station Installation

We have been operating a weather station from our head office in Phnom Penh for nearly 3 years now, as accurate meteorological data in the region has previously been difficult to obtain. Comparing the rainfall recorded with a manual gauge, it was found that the station under recorded the heaviest rainfall events in 2016 by around 20% depending on wind conditions. A new 'aerodynamic shape raingauge cone is now installed and will be tested in 2017 wet season to see if the performance is better than the old style cone.
