Heavy rainfall drives one-third nitrogen runoff according new study
2020/11/13
Heavy rain events that occur only a few days a year can account for up to one-third of the annual nitrogen runoff from farmland in the Mississippi River basin, according to a new study by Iowa St...
SWAMP GIS: A spatial decision support system for predicting and treating stormwater runoff
Stormwater runoff decision support
2015/8/14
SWAMP GIS is a spatially-based decision support system that empowers users in rural areas within Oregon (USA) with tools for predicting and mitigating stormwater runoff. SWAMP GIS is made freely avail...
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...
Estimating land-use change impacts on direct runoff and non-point source pollutant loads in the Richland Creek basin (Illinois,USA) by applying the L-THIA model
