Water quality information in aquatic ecosystems is crucial setting up guidelines for resource management. This study explores the water status and pollution sources Lake Naivasha, Kenya. Analysis of parameters at seven sampling sites was carried out from samples collected weekly January to June biweekly July November 2011. Principal component analysis (PCA) cluster (CA) were used analyse dataset. showed that four principal components (PCA-1 PCA-4) explained 94.2% variability. PCA-1 PCA-2...
Abstract The spatio‐temporal dynamics of the trophic state a lake are crucial in defining its water quality, as well biodiversity. Accordingly, this study focused on variations state, and possible causes heterogeneous turbidity Lake Naivasha, Kenya. oscillated between eutrophic hypereutrophic condition, being found to be more than reported previous studies, indicating progressive deterioration quality. Inferences from graphical representation deviations total phosphorus Secchi depth...
Restoration of the ecosystem services and functions lakes requires an understanding turbidity dynamics in order to arrive at informed environmental management decisions. The spatio-temporal frequent monitoring components such as chlorophyll-a concentration. In this study, we explored use Moderate Resolution Imaging Spectroradiometer Aqua (MODIS-Aqua) satellite data studying changes concentration Lake Naivasha, a turbid tropical system. temporal trend over study period lake was also...
This study describes the mismatch between required knowledge and efforts by scientists stakeholders in Lake Naivasha basin, Kenya. In integrated water resources management (IWRM) suffers from absence of critically relevant knowledge. further presents a spatial assessment framework for supporting IWRM basin. resulted an ongoing debate studying basin's issues. It builds on jointly identified indicators sustainable governance, their interdependency, gaps. For basin this is first important step...
The hydrodynamics in Lake Naivasha, a shallow endorheic lake, are simulated using the Delft3D Flow Module to investigate major driving forces of lake. results showed wind as forcing. zones lake currents movement same direction while deep movements against direction. These findings were confirmed and further explained an idealized model. Limited exchange between Crescent (crater which is temporally separated from during low water levels) main was observed. can explain spatial variability...
This study presents the technical and scientific results obtained through a collaboration between Institute for Environment Sustainability (Joint Research Centre of European Commission) two PUMA Pilot Projects, namely Western Indian Ocean Satellite Application Project (WIOSAP), Monitoring Oceanographic Meteorological in support Management Fisheries Senegal (SEGEPS). Both projects are aimed at an optimized use MSG (Meteosat Second Generation) satellite images to improve management regional...
