Analysis of spatial and temporal drought variability in a tropical river basin using palmer drought severity index (PDSI)
(Academic Journals, 2017-08-31)
Analysis of spatial and temporal drought variability in the upper Tana River basin using Palmer Drought
Severity Index (PDSI) was conducted. The drought is critical for formulation of mitigation measures in
the river ...
Analysis of drought and wet-events using SWSI-based severity-duration-frequency (SDF) curves for the upper Tana river basin, Kenya
(Science Publishing Group, 2018-06-12)
Drought and wet-event patterns in the Upper Tana River basin have significantly been changing due to variation
of climatic and human-induced factors. This paper presents the analysis of drought and wet-events using ...
Analyzing the Mara river basin behaviour through rainfall-runoff modeling
(Scientific Research Publishing, 2017-09-14)
Hydrological models are considered as necessary tools for water and environmental resource management. However, modelling poorly gauged watersheds has been a challenge to hydrologists and hydraulic engineers. Research
done ...
Geochronological and spatial distribution of heavy metal contamination in sediment from lake Naivasha, Kenya
(Taylor & Francis, 2019-01-02)
Sediment cores hold large information on the history of human interactions with lakes and surrounding environments. Hence, this study investigated the geochronological and heavy metals characteristics of sediment from Lake ...
Determination of discrete particles optimum design parameters for surface irrigation system settling basin
(2018-06-05)
Irrigated agriculture is faced with challenges that include sediment loading in the river basins and dams. The
management of sediments in river basins and waterways has been an important issue for water managers throughout ...
Comparative assessment of the effect of climate change and human activities on streamflow regimes in central rift valley basin, Ethiopia
(Science and Education Publishing, 2019)
Climate change and anthropogenic activities are the main driving factors for changes in hydrological
processes of a given watershed. This research was conducted to assess the relative contribution of climate change
and ...
Drought forecasting under climate change scenarios using artificial neural networks for sustainable water resources management in upper Tana river basin, Kenya
(Elsevier, 2018-07-10)
Climate change has continued to impact negatively on water resources globally. For instance, extreme weather conditions especially the drought phenomena have become frequent in Africa. This has prompted water engineers and ...
Bathymetric survey of lake Naivasha and its satellite lake Oloiden in Kenya; using acoustic profiling system
(wileyonlinelibrary.com/journal/lre, 2018-10-23)
Lakes and reservoirs play important roles as freshwater sources for domestic, indus-trial, agricultural, fisheries and recreational purposes. However, for the lakes to be sustainably exploited, there is need to understand ...
Detection of spatial, temporal and trend of meteorological drought using standardized precipitation index (spi) and effective drought index (edi) in the upper Tana river basin.
(Scientific Research Publishing, 2018-07-17)
Drought events across the world are increasingly becoming a critical problem owing to its negative effects on water resources. There is need to understand on-site drought characteristics for the purpose of planning mitigation ...
Simulation of the hydraulics and treatment performance of horizontal subsurface flow constructed wetland treating greywater
(Science Publishing Group, 2018-05-10)
Constructed wetlands (CWs) have evolved as some of reliable wastewater treatment technologies. Various types
of CWs differ in their main design characteristics and in processes responsible for pollutant removal. Classification ...
