Analysis of drought effect on annual stream flows of river Malewa in the lake Naivasha basin, Kenya
(Radiance Research Academy, 2014-09-15)
The main parameters of drought phenomenon are the longest duration and largest severity for a desired return period. These
parameters form the basis for designing water storage structures to cope with drought effects. In ...
A review for hydraulic analysis of irrigation canals using HEC-RAS model: a case study of Mwea irrigation scheme, Kenya
(Science Publishing Group, 2014-12-19)
Hydraulic simulation models could be suitable tools for understanding the hydraulic characteristics of irrigation
systems. In this study HEC-RAS model will be tested in terms of error estimation and used to determine canal ...
Drought forecasting using indices and artificial neural networks for upper Tana river basin, Kenya-a review concept
(OMICS Publishing Group, 2014-01-01)
Due to increased impact of drought on water availability at different scales there is need to understand droughts especially in upper Tana River basin which is a critical and largest water system in Kenya. There is need ...
Simulation of catchment hydrologic response under changing land use: case of upper Molo river catchment, Kenya
(2014)
The urban and agricultural developments have led to changes in catchment hydrologic response. To clearly understand the effect of land use change on catchment hydrologic response, a study was carried out in the Upper Molo ...
Hydrological drought frequency estimation using stream flow drought index and modified gumbel method in upper Tana river basin
(Radiance Research Academy, 2015-11-15)
Objective: To estimate the hydrological drought frequency for upper Tana River basin in Kenya using absolute Stream flow
Drought Index (SDI) and modified Gumbel technique. The frequency of drought event of a defined ...
Evaluating performance of vertical flow constructed wetland under various hydraulic loading rates in effluent polishing
(IWA Publishing, 2011-06-01)
The discharge of untreated wastewater or partially treated effluent and runoff from agricultural fields into water bodies is a major source of surface water pollution worldwide. To mitigate this problem, wastewater treatment ...
The effect of climate change on loss of lake volume: case of sedimentation in central rift valley basin, Ethiopia
(Multidisciplinary Digital Publishing Institute, 2018-12-11)
Evaluating the impact of climate change on sediment yield has become one of the major
topics in climate research. The purpose of this study was to investigate sediment yield contribution to
lake volume change under ...
Assessment of water flow and sedimentation processes in irrigation schemes for decision-support tool development: a case review for the Chókwè irrigation scheme, Mozambique
(Multidisciplinary Digital Publishing Institute, 2019-02-28)
Water flow and sedimentation processes have been significantly erratic at the Chókwè
Irrigation Scheme (CIS) and have affected its hydraulic performance. Given its expansion there
is need to understand these processes ...
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 ...
