“…The contributing upstream area rainfall was extracted from the bias-corrected TRMM mean annual rainfall grid. A continuous parameterization technique (Harvey and Eash, 1996) has been implemented to extract contributing upstream mean rainfall. The continuous parameterization technique uses the same rationale of the flow direction and flow accumulation calculation algorithms, but instead of treating every pixel as one unit, each pixel is weighted by the rainfall value calculated from the bias-corrected TRMM rainfall grid.…”

“…The continuous parameterization technique described by Harvey and Eash (1996) was applied to calculate the upstream area-weighted mean annual rainfall of every pixel on the streams. This parameterization technique uses the same rationale as the flow accumulation algorithm, but instead of treating every pixel as one unit, each pixel is weighted by the rainfall value calculated for the pixel with inverse distance weighted interpolation.…”

AbstractThis study produced a comprehensive estimate of the magnitude of hydropower potential available in the streams that drain watersheds entirely within the State of São Paulo, Brazil. Because a large part of the contributing area is outside of São Paulo, the main stem of the Paraná River was excluded from the assessment. Potential head drops were calculated from the Digital Terrain Elevation Data,which has a 1-arc-second resolution (approximately 30-meter resolution at the equator). For the conditioning and validation of synthetic stream channels derived from the Digital Elevation Model datasets, hydrography data (in digital format) supplied by the São Paulo State Department of Energy and the Agência Nacional de Águas were used. Within the study area there were 1,424 rain gages and 123 streamgages with longterm data records. To estimate average yearly streamflow, a hydrologic regionalization system that divides the State into 21 homogeneous basins was used. Stream segments, upstream areas, and mean annual rainfall were estimated using geographic information systems techniques. The accuracy of the flows estimated with the regionalization models was validated. Overall, simulated streamflows were significantly correlated with the observed flows but with a consistent underestimation bias. When the annual mean flows from the regionalization models were adjusted upward by 10 percent, average streamflow estimation bias was reduced from -13 percent to -4 percent. The sum of all the validated stream reach mean annual hydropower potentials in the 21 basins is 7,000 megawatts (MW). Hydropower potential is mainly concentrated near the Serra do Mar mountain range and along the Tietê River. The power potential along the Tietê River is mainly at sites with medium and high potentials, sites where hydropower has already been harnessed. In addition to the annual mean hydropower estimates, potential hydropower estimates with flow rates with exceedance probabilities of 40 percent, 60 percent, and 90 percent were made.

“…For example, Harvey and Eash (1996) developed Basinsoft to quantify certain selected morphometric characteristics such as watershed area, length, slope, relief, and so on for a drainage basin using digital cartographic data. Apaydin et al (2006) also indicates that detailed geomorphologic characteristics need to be compiled for performing hydrologic modelling of a basin to show the relationship among these characteristics.…”

WinBasin is a GIS-based watershed analysis system that can automatically calculate depressionless flow directions, delineate watersheds/sub-watersheds, extract realistic drainage networks, and calculate geomorphological indices and hydrological responses from digital elevation models. Several improved algorithms coupled with GIS techniques were proposed for automated watershed analysis. First, different from depression fill-up treatment methods, the depression watershed method coupled with the improved fuzzy c-mean algorithm allows the depression outlet location and flow directions to be determined. Second, by using the GIS-based point-and-click interface coupled with outlet-tracing and headwater-tracing algorithms, watersheds with user-specified outlets and realistic drainage networks can be easily extracted based on the derived flow directions. The analysed results can be exported to vector format for linkage with other GIS software. Third, the geomorphological indices and hydrological responses (width function and geomorphological instantaneous unit hydrograph) in a watershed can also be instantly derived based on the proposed algorithms and the GIS technique
