Evaluation of total runoff for the Rio San Pedro sub-basin (Nayarit, Mexico) assessing their hydrologic response units
Runoff hydrologic response unit curve number land uses
2015/8/14
The Rio San Pedro sub-basin runoff was estimated using the curve number method (NRCS-CN) applied to hydrologic response units (HRU’s), derived from remote sensing and GIS analysis. The sub-basin (arou...
Impact of landuse on runoff in mountain catchments of different scales
