Humans reshape wetlands: Unveiling the last 100 years of morphological changes of the Mara Wetland, Tanzania

The Lower Mara River and Wetland, Tanzania, is an important ecosystem and unique water resource for a vast semi-arid area. The river, an affluent of Lake Victoria, and the wetland are experiencing morphological and vegetation changes resulting in channel avulsions and wetland expansion. This study analyses the changes over the last 100 years...

Early warnings of hazardous thunderstorms over Lake Victoria

Weather extremes have harmful impacts on communities around Lake Victoria in East Africa. Every year, intense nighttime thunderstorms cause numerous boating accidents on the lake, resulting in thousands of deaths among fishermen. Operational storm warning systems are therefore crucial. Here we complement ongoing early warning efforts based on...

MAFURIKO: Design of Nzoia Basin location based flood game

Every 2 to 7 years, Kenya experiences a reoccurrence of El-Niño rains leading to loss of life and massive damage to property. The 1997/98 El-Niño floods affected 1.5 million persons and led to an estimated USD 1.2 billion infrastructural damage, USD 236 million agricultural damage and USD 9 million on other losses (property, soil erosion,...

Evaluating MERIS-Based Aquatic Vegetation Mapping in Lake Victoria

Delineation of aquatic plants and estimation of its surface extent are crucial to the efficient control of its proliferation, and this information can be derived accurately with fine resolution remote sensing products. However, small swath and low observation frequency associated with them may be prohibitive for application to large water bodies...

A Hybrid Approach to Combine Physically Based and Data-Driven Models in Simulating Sediment Transportation

The objective of this study is to develop a methodology for hybrid modelling of sedimentation in a coastal basin or large shallow lake where physically based and data driven approaches are combined. This research was broken down into three blocks. The first block explores the possibility of approximating a physically based model using a data...
