Estimating bathymetric information is vital for aquaculture and navigation applications. Free, high-resolution satellite imagery provides a cost-effective solution routine measurements. We tested six algorithms to retrieve water depth in the Mwanza Gulf of Lake Victoria using Sentinel-2 imagery: conventional Stumpf method, Random Forest (RF), Gradient Boosting Machine (GBM), Extreme (XGB), Neural Network (NNET), Support Vector (SVM). In-situ points collected via echo sounders were used train...
Abstract The current study was carried out to examine the spatial and temporal variations of physicochemical water quality parameters Lake Bunyonyi. observations were made on surface Bunyonyi for 1 year determine quality. basic 12 variables used measured monthly at nine stations. Water temperature, dissolved oxygen (DO), turbidity, electric conductivity (EC), pH Secchi depth (SD) in field, while like total nitrogen (TN), phosphorus (TP), nitrite-nitrogen (NO 2 -N), nitrate-nitrogen 3 soluble...
Determinations of spatial and temporal variations in organic matter nutrient dynamics water sediments are crucial for understanding changes aquatic bodies. In this study, we (i) determine the dissolved inorganic nutrients, during transition from dry to rainy season, (ii) provide future productivity predictions Rufiji Delta mangroves, Tanzania, based on input various nutrients. Water samples were collected six locations, three times per year between April 2012 January 2014, analysed total...
Abstract The study was conducted to assess the spatial and temporal variations of trophic state condition Lake Bunyonyi between October 2019 September 2020. Secchi depth (SD), total phosphorus (TP) chlorophyll- a (Chl- ) concentration were measured aid quantification lake using Carlson index (CTSI). (TSI) values based on SD, TP Chl- 60.82 ± 5.35, 68.99 11.04 61.74 7.51, respectively. March 2020 recorded highest mean CSTI value (70.14 4.04), while in 2020, lowest (58.03 6.22) obtained. Based...
Abstract Lake Bunyonyi is one of the major resources social-economic potential in districts Rubanda and Kabale, South-Western Uganda. The lake’s sub-catchment faces environmental problems because intensive agriculture, settlement, business tourism activities, which consequently cause pollution water system. This study, therefore, intended to determine processes that govern nitrogen dynamism using a numerical model takes into account various system STELLA® 8.1.1 software. From simulation, it...
Lake Bunyonyi ecosystem plays vital roles in water resource conservancy and tourism. Nevertheless, the rapid increase human population unrelenting activities are threatening values, functions, ecological integrity of lake. In this study, public perceptions drinking quality its health implications Sub-catchment, Western Uganda presented. A closed-ended questionnaire was administered to 267 respondents living within one Kilometre away from lake shores. Besides, observation interview methods...
Abstract Stagnating capture fisheries and increasing fish protein demand necessitate aquaculture production to bridge the gap. Lake Victoria is a potential water body for through cage farming. The sustainability of farming depends on timely holistic site selection. However, current selection methods involve complex, resource‐intensive field surveys that lack approach integrate multiple factors. Accordingly, information regarding suitable sites sustainable in remains scarce. In this study,...
Abstract Background Microbial water quality serves to indicate health risks associated with the consumption of contaminated water. Nevertheless, little is known about microbiological characteristics in Lake Bunyonyi. This study was therefore undertaken examine spatial and temporal variations faecal indicator bacteria (FIB) relation physicochemical parameters Result The FIB concentration consistently measured during sampling months correlated each other showing presumed human pollution lake....
Seagrasses are marine flowering plants found in both temperate and tropical coastal environments, that offer vital ecosystem services adaptations. However, due to their proximity the shore, they heavily impacted by human activities climate change, endangering seagrasses services. To manage seagrass meadows effectively sustainably, detailed monitoring is essential. Unfortunately, past under-prioritization of reliable baseline data impedes understanding dynamics rapid response declines. This...
