Floods are a natural phenomenon that occurs every year in several regions of Indonesia. This phenomenon is very detrimental to all aspects of life of the affected community who ultimately have to sacrifice property and even lose their lives.
Prof. Ir. Agus Suharyanto, M.Eng., Ph.D. was inaugurated as a professor in the field of Sustainable Water Resources offering the Hyetograph-Hydrograph Flood Model, Thursday (11/28/2024). This model uses remote sensing satellite imagery to estimate land surface temperature (earth). And conduct hydrograph analysis (surface water flow) in relation to climate change.
“Changes in the earth’s surface temperature (Land Surface Temperature-LST) are caused by a decrease in vegetation covering the earth’s surface. The increase will affect the characteristics of rainfall. As a result, there is often short-duration rain with high intensity,” he said.
The professor who completed his Masters and Doctoral education in Japan said that current climate change is marked by global warming and has recently become a global boiling. This is the impact of the increase in LST which can accelerate cloud formation.
This research related to LST was conducted in Malang City, Batu City, Surabaya City, Malang Regency, Pasuruan, Probolinggo, Sampang, and Tuban.
In his research, Prof. Agus also concluded that the higher the imp (water impermeable layer), the greater the surface water flow discharge that occurs. This impermeable layer is like buildings, asphalt, concrete. To overcome this, infiltration wells and detention ponds can be used which are quite significant in controlling flooding in an area.
