Study on the effects of vegetation density in reducing bed shear stress on the downstream slope of earthen embankment

  River bank, coastal erosion and embankment failures are endemic and recurrent natural hazards, causing loss of lands and livelihoods along major rivers and coastlines. Overflow is the most damaging factor for earthen embankments on the downstream (d/s) slope due to the erosion of surface material which is caused by the high bed shear stress and supercritical flow over the entire d/s slope. Vegetation planted...

Housing typology in the forecast of demand for drinking water in developing country towns and cities: Application to Yaoundé - Cameroon

  The lack of mastery of housing problems in developing countries causes difficulties in the forecasting of the demand for potable water, which in turn causes waste and high cost of water. We modeled the forecasting of the demand for potable water in a city, taking into account the housing typology. The latter depends on parameters such as: household income, size of households, price of water, annual rainfall...
