Assessment of Hydro-climatic Trends and Variability over the Black Volta Basin in Ghana

Abungba, J. A.; Khare, D.; Pingale, S. M.; Adjei, K. A.; Gyamfi, C.; Odai, S. N. (Springer Science and Business Media Deutschland GmbH, 2020)

The present study examines the trends of hydro-climatic parameters over the Black Volta Basin in Ghana. Trend analysis was carried at different time scales (i.e., monthly, seasonal, and annual) from 1961 to 2016. Modified ...
Estimating the spatial distribution of evapotranspiration within the Pra River Basin of Ghana

Nsiah, J. J.; Gyamfi, C.; Anornu, G. K.; Odai, S. N. (Elsevier Ltd, 2021)

It is important in water resource planning to accurately estimate the spatial distribution of evapotranspiration (ET) as an input parameter for hydrological studies. Although, conventional pan evaporation, lysimetric and ...
Evaluation and Comparison of Satellite Rainfall Products in the Black Volta Basin

Logah, F. Y.; Adjei, K. A.; Obuobie, E.; Gyamfi, C.; Odai, S. N. (Springer Science and Business Media Deutschland GmbH, 2021)

This study evaluated the performance of five satellite rainfall products (CHIRPS, PERSIANN, TRMM, RFE, and ARC) in the Black Volta Basin (BVB) using four performance evaluation methods: pairwise statistics, categorical ...
Evaluation of RFE Satellite Precipitation and its Use in Streamflow Simulation in Poorly Gauged Basins

Darko, S.; Adjei, K. A.; Gyamfi, C.; Odai, S. N.; Osei-Wusuansa, H. (Springer Science and Business Media Deutschland GmbH, 2021)

Abstract: The performance of satellite Rainfall Estimates (RFE, version 2.0) at daily resolution was evaluated in comparison with ground-based meteorological datasets (GBD) by applying statistical and hydrological modeling ...
Evolutional characteristics of hydro-meteorological drought studied using standardized indices and wavelet analysis

Gyamfi, C.; Amaning-Adjei, K.; Anornu, G. K.; Ndambuki, J. M.; Odai, S. N. (Modeling Earth Systems and Environment, 2019)

The study presents a more recent historical analysis of hydro-meteorological droughts in the Olifants Basin, South Africa from 1980 to 2013 using the Standardized Precipitation Index (SPI), the Standardized Precipitation ...
Implications of land use/land cover changes and climate change on black volta basin future water resources in Ghana.

Abungba, J. A.; Adjei, K. A.; Gyamfi, C.; Odai, S. N.; Pingale, S. M.; Khare, D. (Sustainability, 2022)

The Black Volta River basin faces several challenges, which impede the sustainability of its water resources and biodiversity. Climate change coupled with land use/land cover (LULC) change patterns account for most of the ...
Modelling the recent variations of water balance components and water availability within the Senegal River basin: using WEAP21 model.

Thiam, M.; Adjei, K. A.; Niang, A.; Gyamfi, C.; Odai, S. N.; Kane, A. (Modeling Earth Systems and Environment, 2022)

The availability of water in the Senegal River basin is a basic issue for moving towards efficient resource management. Given the extent of the river and the large number of stations, hydrological modelling is a reliable ...
Potential for small hydropower development in the Lower Pra River Basin, Ghana

Arthur, E.; Anyemedu, F.O.K.; Gyamfi, C.; Asantewaa - Tannor, P.; Adjei, K. A.; Anornu, G. K.; Odai, S. N. (Elsevier B.V., 2020)

Study region:: Lower Pra River (LPR) Basin, Ghana Study focus:: This study examines the potential for Small Hydropower Development in a semi-arid environment albeit the lack of data. Geographic and site specific information ...
Quantifying and analysing water trade-offs in the water-energy-food nexus: The case of Ghana.

Opoku, E. K.; Adjei, K. A.; Gyamfi, C.; Vuu, C.; Appiah-Adjei, E. K.; Odai, S. N.; Siabi, E. K. (Water-Energy Nexus, 2022)

Water, Energy and Food (WEF) are inextricably linked, and the Water-Energy-Food nexus (WEF nexus) provides a comprehensive framework for addressing the complex and intricate interconnections in the development of these ...
Quantitative management of groundwater resources in regional aquifers under uncertainty: A retrospective optimization approach.

Kifanyi, G. E.; Ndambuki, J. M.; Odai, S. N.; Gyamfi, C. (Groundwater for Sustainable Development, 2019)

Simulation-optimization models have been widely developed and used for many decades in groundwater resource management. However, simulation-optimization models in most applications encompass data that are subject to ...
Stochastic modelling of great letaba river flow process

Kifanyi, G. E.; Ndambuki, J. M.; Odai, S. N.; Gyamfi, C. (Journal of Geoscience and Environment Protection, 2019)

A stochastic approach is presented in view that a time series modelling is achieved through an Autoregressive Moving Average (ARMA) model. The applicability of the ARMA model is then further presented using the Great Letaba ...
