A computer based tool for determination of optimal size rainwater storage tank
Obiero, J.P.O (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 ... -
Design of an optimal size Rainwater Storage Tank
Obiero, J.P.O (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 ... -
Estimation of Infiltration Parameters at the Steepland Research Station, Kabete, Nairobi, Kenya
Obiero, J.P.O (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 ... -
Evaluation of Infiltration using the Green-Ampt model for catchments in Kenya,
Obiero, J.P.O (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 ... -
How reliable are cylinder infiltrometers in determining the infiltration characteristic of a soil?
Obiero, J.P.O (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 ... -
Rainwater Harvesting for Crop Production in Semi-arid Areas
Obiero, J.P.O; Thine, C.O.; Mbuge, D.O. (2003)This paper presents an analysis of economics of rainwater harvesting by poor farmers in Tanzania. A questionnaire was used to survey 120 households to obtain information on the performance of their enterprises over 6 years ... -
Surface runoff prediction on Kenyan catchments using the Green-Ampt model and related soil parameters
Obiero, J.P.O (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 ...
