Hydrologic processes of groundwater in a small monsoon-influenced mountainous watershed

Hydrologic Response of a Small Watershed Model to Generated Precipitation

Watershed models such as SWAT (Soil and Water Assessment Tool) simulate water quality impacts of land and water resource management alternatives. To simulate these impacts, long-term daily rainfall data are necessary. In the absence of measured rainfall data, watershed models use weather generators to simulate rainfall events. The objective of this study is to examine several daily precipitatio...

The Characteristics of Extreme Erosion Events in a Small Mountainous Watershed

A large amount of soil loss is caused by a small number of extreme events that are mainly responsible for the time compression of geomorphic processes. The aim of this study was to analyze suspended sediment transport during extreme erosion events in a mountainous watershed. Field measurements were conducted in Wangjiaqiao, a small agricultural watershed (16.7 km(2)) in the Three Gorges Area (T...

Predication of sediment delivery ratio in a small agricultural watershed

Episodic wood loading in a mountainous neotropical watershed

a r t i c l e i n f o The Upper Rio Chagres drains 414 km 2 of steep, mountainous terrain in central Panama. A tropical air mass thunderstorm on 10 July 2007 produced a flood across the basin that peaked at 720 m 3 s − 1 at a headwaters gage draining 17.5 km 2 and 1710 m 3 s − 1 at a downstream gage draining 414 km 2. The storm also triggered numerous landslides in the upper basin, which facili...

Application of a Conceptual Hydrologic Model in Teaching Hydrologic Processes*

In this study, a hands-on modeling tool is developed for students in civil engineering and earth science disciplines to help them learn the fundamentals of hydrologic processes and basic concepts of model calibration and sensitivity analysis, and practice conceptual thinking in solving and analysis of engineering problems. This modeling tool aims to provide an interdisciplinary application-orie...
