水環境国際招聘賞（いであ招聘賞）（JSWE‑IDEA Water Environment InternationalExchange Award）授賞に関して
本会では，水環境分野の国際交流・国際協力の促進を目的として，いであ株式会社からのご出捐により，水環境国際招聘賞と水環境国際活動賞を設けております。水環境国際招聘賞は本会年会で研究発表を行う海外在住外国人会員に対して，来日費用等の助成を行う制度です。第 50 回年会には中国，オーストラリアから各 1 名を招聘し，研究発表を行っていただきました。発表を終えて帰国された受賞者に参加報告を書いていただきましたので，ご紹介します。
なお，今年度の水環境国際招聘賞の募集案内は夏頃に本誌会告に掲載する予定です。

My Experience in 50th Annual Conference of JSWE, Tokushima
Senior Research Fellow, Natural & Built Environments Research Centre,
School of Natural and Built Environments, University of South Australia（南オーストラリア大学，上席研究員）

Rupak Aryal
It was my great pleasure to participate to 50th Annual
Conference of JSWE under the Overseas Member
Invitation Program supported by JSWE held inTokushima, a beautiful city with hills and mountains
and full of history and unique culture. It was also greathonour for me to receive the JSWE-IDEA Water
Environment International Exchange Award.
I obtained the doctoral degree in the ﬁeld ofEnvironmental Engineering from the University ofTokyo in 2003 and then joined as a postdoctoral
research under the project Core Research for Evolution
Science and Technology（CREST）at the University ofTokyo till 2005. After leaving Japan for the last 12years, I worked in diﬀerent universities across theglobe in （University of South Australia （2012‑ tillnow）; The University of Queensland （2010‑2012）;
University of Technology, Sydney （2007‑2010）,
University of Ulsan （2006‑2007）, Kathmandu
University （2005‑2006）） in water/stormwater andwastewater related areas.
My current research focuses on water quality andpollutant transport. Australia and many other countries
face frequent ﬂood and drought due to climate change.
Because of environmental anomaly, catchment receives
unusual rainfall pattern frequently that alters waterquality in stormwater receiving water bodies. At theend of year 2010, nearly 700 mm rainfall occurred inthree weeks period in South East Queensland, Australia.
Inﬂux of water during the ﬂood period quickly ﬁlled
the Lake Wivenhoe to 191% in three weeks anddischarged massive load of sediment and organic to theVol. 39（A） No. 6（2016）lake and altered water quality in a short period of time.
Being this Lake a source of water to nearly half million
people of Brisbane city, understanding of change inwater quality both spatially and vertically in real time
was of interest to all stakeholders including scientists,engineers and water treatment plant operators. With an
aim to identify simple, rapid and cost eﬀective method
to monitor water quality in Lake Wivenhoe, we used
number of optical spectroscopy methods and one of themwas ﬂuorescent spectroscopy. The work I presented in50th Annual Conference of JSWE was application of
ﬂuorescent spectroscopy in monitoring of water quality
and obtaining qualitative and quantitative information
to make water treatment easy for operators intreatment plant.
This was my second time to attend JSWE annualconference. I was very much impressed with thenumber of participants and the scope of thepresentation that touched many current issues, futurechallenges of water and wastewater and also opened
doors to tackle and solve them. During the conference
period, I got an opportunity to interact with colleagues,professors and water industry professionals. Thisconference helped me to know many frontier research
work and build networks and ﬁnd research partners
for future collaboration with Japanese partners.
Finally, I would like to express sincere thanks toorganising committee, volunteers and academic andindustry participants that make the event successful
and wonderful.
