Knowledge of design peak flow is crucial in various applications related to hydrology, hydraulics and water resources management. However, obtaining challenging especially ungauged basins lacking discharge observations, a circumstance that does not allow the calibration advanced hydrological models. Recently, new method called EBA4SUB (Event-Based Approach for Small Ungauged Basins) was introdu...

Droughts are natural disasters with a significant impact on the economy and social life. Prolonged droughts can cause even more damage than floods. The novelty of this work lies in definition synthetic drought hydrograph (SDH) which be derived at each gaging station river network. Based hydrographs (DHs) recorded for selected station, SDH is statistically characterized provides valuable informa...

Flash floods are water-related disasters that cause damage to properties, buildings, and infrastructures in the flow path. often occur within a short period of time following intense rainfall high, mountainous area northern Thailand. Therefore, purpose this study is generate flash flood susceptibility map using watershed morphometric parameters hydrological approaches. In study, Pai River basin...

Makassar City is often experiences flood during rainy season and lack of water dry season. Therefore, Jenelata Dam planned to be built in South Sulawesi with a watershed area 221.22 km2. Every dam has dambreak potential due many factors such as earthquakes. Risk analysis carried out order study the most effective mitigation plan on minimizing risk index. Flood hydrograph modeling done using HEC...

In this study, we use a lattice Boltzmann method with multi-relaxation-time model to simulate dam-break flooding in confluence channels four angles. Compared physical experiment, the simulation proves reliable. We analyze influence of angle on propagation flood. The stage hydrograph at area can be divided into stages: before wavefront reaches—rising rapidly—falling gradually—planarization perio...

The yields of the tropical rivers of Southeast Asia supply large quantities of carbon to the ocean. The origin and dynamics of particulate organic matter were studied in the Houay Xon River catchment located in northern Laos during the first erosive flood of the rainy season in May 2012. This cultivated catchment is equipped with three successive gauging stations draining areas ranging between ...
