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 ...

Travel pattern is a key element in transportation planning and policy formulation. Modal share analysis can provide useful information of university travel demand which is important in the development of transport policies. ...

Studies were carried out to artificially breed an optimized solar tunnel dryer using genetic algorithms (GAs). The energy harnessed by the dryer was simulated in Visual Basic Script (Microsoft Visual Basic Script 2010TM) ...

Kajiado County is an arid and semi-arid area in Kenya that experiences frequent flash floods. Most of the water evaporates due to the high temperatures experienced in the area. However, to attain reasonable crop yield the ...

In day to day life, millions and millions of liters of water is being wasted through overflowing or excessive usage. In Kitui specifically, water availability by itself a challenge since the area rarely ...

In the present study, temporal and spatial drought-risk events are characterized using a Modified Surface Water Supply Index (SWSI) for upper Tana River basin, located in tropics, Kenya. Forty years (1970-2010) ...

This study sought to characterise sediments in the unlined canal in Chókwè Irrigation Scheme (CIS), during dry (DS) and wet (WS) seasons. Laboratory analysis were performed on the sediment’s soluble extracts for pH, ...

This paper describes the damage behaviors of plain-woven basalt-unsaturated polyester laminates under low-velocity impact from experimental and finite-element approach. Experimental tests were carried out in an INSTRON® ...

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 ...

This article uses the non-linear integrated drought index (NDI) for managing drought and water resources forecasting in a tropical river basin. The NDI was formulated using principal component analysis (PCA). The NDI used ...
