Hydrological classification of the Besease inland valley bottom in Ghana for crop production using the water table fluctuation method

The shapes and forms of piezometric hydrographs arising from the recharging and discharging of unconfined aquifers offer a hydrological tool for the classifications of inland valley bottoms in Ghana for crop production. A two-year measured water table fluctuations at Besease wetlands were plotted on a reference scale of time in months on the x-axis and hydraulic head on the y-axis. The water table fluctuation method was...

Wet and dry spell analysis for decision making in agricultural water management in the eastern part of Ethiopia, West Haraghe

The objective this study was to analyze the dry and wet spell of the main and small rainy season in the eastern part of Ethiopia, West Haraghe. Markov Chain model was employed to investigate the extent and characteristics of the dry and wet spell in the study sites. Accordingly, the results exhibited that the chance of having wet dekades is relatively higher (greater than 50% of probability of occurrences) during last...
