Modelling soil erosion and sediment yield at a catchment scale: the case of Masinga catchment, Kenya
(John Wiley & Sons, Ltd., 2006-08-07)
Development of improved soil erosion and sediment yield prediction technology is required to provide catchment stakeholders with the tools they need to evaluate the impact of various management strategies on soil loss and ...
Classification of catchment risk areas using spatially distributed event-based soil erosion: a case of upper Njoro river catchment, Kenya
(WIT Press, 2008-12-19)
Human-induced soil erosion and drastic change in land use practices have adversely infl uenced the land degradation
and surface runoff response in upper Njoro River catchment. The drainage area is approximately 127 km2.
Due ...
Detection of trends in extreme streamflow due to climate variability in the lake Naivasha basin, Kenya
(2014-11-17)
Variability of streamflow has far-reaching impacts especially in developing countries. This is aggravated by climate change which has adversely affected the water resources and food security. This paper presents the ...
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 ...
Analysis of manual and centralised supervisory control operations to improve level of service: a case study of pyramid hill no 1 channel, Victoria, Australia
(Kluwer Academic Publishers, 2001-02)
The current challenge facing irrigation inAustralia is tofind ways to improve the operationalperformance of existing systems rather thanconstructing new ones. Unsteady flowsimulation models are often used as keytools to ...
The ROSA project–a new approach to sustainable sanitation in Eastern African cities
(2008-09)
The ROSA project promotes resources-oriented sanitation concepts as a route to sustainable and
ecologically sound sanitation. These concepts shall be applied in four cities in Eastern Africa,
namely Arba Minch (Ethiopia), ...
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 ...
