Impacts of Rain Water Harvesting in Kusa
(2005)Annual seasonal droughts of 2-4 months occur in Kusa limiting access of households to safe drinking water. This compounds the health and socio-economic disasters through increased water borne diseases rated at 10% morbidity ... -
Using roof-storage rainwater systems as a coping strategy on drought related disasters
(2006)Annual seasonal droughts of 2-4 months occur in Kusa limiting access of households to safe drinking water. This compounds the health and socio-economic disasters through increased water borne diseases rated at 10% morbidity ... -
Integrated water, energy and sanitation solution for stand alone settlements
(2005)Lake Victoria basin has a large rural and rapidly growing peri-urban population that lacks sustainable solutions to safe and adequate water supply, energy and sanitation. Access to safe water and sanitation was 60% and ... -
How reliable are cylinder infiltrometers in determining the infiltration characteristic of a soil?
(1994)A number of methods are discussed for obtaining a reasonable estimate of the infiltration function for irrigation borders. Data from ring infiltrometers are fit to power functions for infiltration rate and cumulative ... -
Surface runoff prediction on Kenyan catchments using the Green-Ampt model and related soil parameters
(1995)The need for more agricultural areas stemming from population pressure has been contributing to the increased forest and grassland-to-agricultural areas conversion in recent years in the upper Mara River Basin, Kenya. The ... -
Estimation of Infiltration Parameters at the Steepland Research Station, Kabete, Nairobi, Kenya
(1997)This study proposes a method for the estimation of lag time of forested mountainous watersheds. Hydrological flood-flow design methods require a time parameter, such as lag time or time of concentration, to estimate peak ... -
Design of an optimal size Rainwater Storage Tank
(1999)Melbourne is facing a severe drought having its 12th consecutive below average rainfall year. Water authorities have been forced to impose rigorous water restrictions including voluntary per capita water use targets after ... -
A computer based tool for determination of optimal size rainwater storage tank
(2000)Rainwater tanks have become popular in large Australian cities due to water shortage and greater public awareness towards sustainable urban development. Rainwater harvesting in multi-unit buildings in Australia is less ... -
Modelling Hydraulic Conductivity
(2001)A simple analytic model is proposed which predicts the unsaturated hydraulic conductivity curves by using the moisture content-capillary head curve and the measured value of the hydraulic conductivity at saturation. It is ... -
Evaluation of Infiltration using the Green-Ampt model for catchments in Kenya,
(2001)This article briefly reviews the hydrologic components of prominent models used in agricultural and mixed land use watersheds and presents the current state‐of‐the‐art in agricultural watershed modeling. The models included ... -
Dryland Farming Technologies
(2004)Arid and semiarid regions comprise almost 40% of the world’s land area and are inhabited by some 700 million people. Approximately 60% of these drylands are in developing countries. Low rainfall areas constitute from 75–100% ... -
Soil Erosion Engineering.
(2007)This article presents a broad review of the physical process of soil erosion, but with the main focus on the approaches, forms of equations, and techniques commonly adopted to quantify the rate of soil detachment in an ... -
Modelling snowmelt in Thiba catchment in central Kenya
(2001)We established, calibrated, and validated a distributed hydrological model for the Thiba catchment in central Kenya. In the 1990s the catchment experienced a sharp increase in the use of water for agriculture. This study ... -
Modelling of irrigation Water Movement in a Distributed Runoff Model,
(2002)The paper forms the first part of an introduction to the SHE, a physically-based, distributed, catchment modelling system produced jointly by the Danish Hydraulic Institute, the British Institute of Hydrology and SOGREAH ... -
Development of a distributed runoff model for a catchment with irrigation systems in Kenya
(2002)A lack of technical knowledge has been identified as one of the primary factors preventing widespread adoption of rainwater harvesting amongst resource-poor farmers in semi-arid Tanzania. Experiments can fill this gap and ... -
Changes and Improvement in Water Management Practices in the Mwea Irrigation Scheme
(2003)n experiment to assess the impact of intermittent irrigation on Anopheles larval populations, rice yields and water use was conducted in the Mwea rice irrigation scheme in Kenya. Four water regimes including intermittent ... -
High Resolution Hip-joint Socket Imaging using Pulsed Laser Radar
(2000)In this paper, we present a 3D imaging technique for computer-assisted hip-joint replacement surgery. It is based on a high resolution laser radar which uses powerful picoseconds laser pulses, generated from low-cost ... -
A Non-invasive Registration Technique in Hip-joint Replacement Surgery Using Laser Radar Imaging
(2004)In this paper, we present a 3D imaging technique for computer-assisted hip-joint replacement surgery. It is based on a high resolution laser radar which uses powerful picosecond laser pulses, generated from low-cost ... -
Non-invasive Intraoperative Imaging using Laser Radar System in Hip-joint Replacement Surgery
(2004)This paper explores the possibility of employing a non-invasive registration technique using a high resolution pulsed laser radar system as an intraopera tive imaging system in computer assisted hip-joint replacement ... -
Clinical Trial of Intraoperative Laser Radar Imaging in Hip-joint Replacement Surgery
(2004)This paper explores the possibility of employing a non-invasive registration technique using a high resolution pulsed laser radar system as an intraopera tive imaging system in computer assisted hip-joint replacement ...
