A parameter estimation method is developed for both transient and steady-state flow models based on genetic algorithms (GAs), one of the increasingly popular global optimization methods. Since GA is independent of the nature of the simulation model and the form of the objective function, any flow simulation code can be used for the forward modelling. The US Geological Survey modular flow simula...

We applied information theory to quantify parameter uncertainty in a groundwater flow model. A number of parameters in groundwater modeling are often used with lack of knowledge of site conditions due to heterogeneity of hydrogeologic properties and limited access to complex geologic structures. The present Information Theory-based (ITb) approach is to adopt entropy as a measure of uncertainty ...

In Ethiopia, groundwater is the main source of freshwater to support human consumption and socio-economic development. Little Akaki watershed located in Upper Awash basin, known for its high annual rainfall considered as potential recharge zone. On contrary, urbanization industrial expansion are increasing at an alarming rate area. This became a concern threatening resources’ sustainability. To...
