Comparing the monitoring and evaluation systems of watershed management related development projects in Amhara, Ethiopia

2012

Natural resource degradation is both a cause and a result of poverty in Ethiopia. Therefore it is important to include watershed management into efforts to reduce poverty and food insecurity in the country. In order to see if different interventions are effective in restoring the degraded environment, it is important to have a functioning monitoring and evaluation system that includes natural resource degradation and other environmental factors. This study compares the monitoring and evaluation systems used by five different projects involved in watershed management in the Amhara region, Ethiopia. The objective is to find out whether these systems are providing adequate and scientifically v…

Derivation of a Distributed Unit Hydrograph Integrating GIS and Remote Sensing

2007

The paper describes the results of a study based on the integration of remote sensing and geographical information system techniques to evaluate a distributed unit hydrograph model linked to an excess rainfall model for estimating the streamflow response at the outlet of a watershed. Travel time computation, based on the definition of a distributed unit hydrograph, has been performed, implementing a procedure using (1) a cell-to-cell flow path through the landscape determined from a digital elevation model (DEM); and (2) roughness parameters obtained from remote sensing data. This procedure allows the taking into account of the differences, in terms of velocity, between the hillslopes and t…
