The assessment of water resource responses to climate change is required in water resource planning and management, protecting environmental quality, and managing watersheds. This study modeled surface runoff and baseflow responses to variations in precipitation (0%, ±10%, and ±20%) and temperature (0 ◦C, ±1 ◦C, and ±2 ◦C) in 25 types of scenarios in the Lanhe Watershed (1140 km2), which posses...

Emerging technologies of remote sensing and GIS were integrated to estimate runoff for watershed basins in China Taipei and Florida. Two basins were selected in each region, with each pair representing a static and a developing case. Remotely sensed images from the Landsat 4, 5, and 7 satellites were used to develop land cover maps of the study areas for the years 1990, 1995, and 2000. GIS anal...

This research presents an integration of remote sensing and GIS for determining the runoff coefficient (C) recommended by the American Society of Civil Engineers and the Water Pollution Control Federation in 1969. The C is a runoff index used as an input parameter in the most commonly used procedure: the rational method for storm-water runoff calculation in small urban watersheds for storm drai...

In this study, the time–area curve of an ellipse is analytically derived by considering flow velocities within both channel and hillslope. The Clark IUH also solving continuity equation with input to linear reservoir. then evaluated application Seolmacheon basin, a small mountainous basin in Korea. findings study are summarized as follows. (1) can more realistically be hillslope velocities. rol...

In this study lake levels of Lake Tana are simulated at daily time step by solving the water balance for all inflow and outflow processes. Since nearly 62% of the Lake Tana basin area is ungauged a regionalisation procedure is applied to estimate lake inflows from ungauged catchments. The procedure combines automated multi-objective calibration of a simple conceptual model and multiple regressi...

Landform, drainage pattern, slope, soil, vegetation and land use/land cover, all of which control surface runoff and peak flow, can be evaluated and mapped reliably and reasonably through Landsat Thematic Mapper (TM) false colour composites of the post-monsoon season. Runoff curve numbers (CAO determined from those data predicted the runoff depth and peak flow with a coefficient of determinatio...

• Rainfall intensity is the dominant hydro-meteorological control of runoff response from peatland catchments in high magnitude storms. Runoff processes even saturation-excess overland flow landscapes are sensitive to scale.
