The Rainfall Simulator

On my last day in Busan, I presented at a low impact development (LID) seminar hosted by Pusan National University for project team members and graduate students. The focus of the seminar was showing on-the-ground examples of LID. Case studies demonstrated how LID has been applied in past projects. We also discussed necessary site investigation […]

The Pusan National University LID Research Group

On Wednesday morning, I did some sight see with Dr. Hyunsuk Shin of Pusan National University. He took me to Beomeosa Temple, located on a mountain above Busan. The original table was constructed approximately 1,000 years ago and is still being used for prayer by many South Koreans. After lunch, the low impact development (LID) research group […]

Data Help Identify Water Resource Trends

Gravity Recovery and Climate Experiment (GRACE) data from the National Aeronautics and Space Administration (NASA) provide a wealth of information to assess changes in the world’s hydrologic cycle — from groundwater depletion and drought to extreme flooding. GRACE’s satellite imagery could be used to improve water management at regional and national scales, saving lives and […]

Moving Forward with LID in South Korea

Today, I met with Dr. Hyunsuk Shin of Pusan National University. He provided an overview of the low impact development (LID) research facility. The center will be built adjacent to an existing earthquake research building on the university’s second campus in the next four years. Researchers will evaluate LID concepts in South Korea, examining infiltration […]

Water Quality Initiatives in Singapore Promote Sustainable Stormwater Management

Singapore is a low-lying country with abundant rainfall, and during the last 30 years, Singapore’s government has spent more than $2 billion to improve stormwater drainage infrastructure. According to Singapore’s Public Utilities Board (PUB), two-thirds of Singapore’s land surface functions as drinking water catchment areas, making it very important to maintain good water quality. One […]
