Innovative Sensor Networks in Ghana: Operating and validating sensor networks for river discharge in Ghana during the wet season

In a Ghana project, field measurements at the Black Volta aimed to enhance hydrological predictions for the Bui power dam. Validating devices and exploring floodplain contributions, such as with GNSS reflectometry and cameras, provides crucial insights for dam management and model improvement.<br/><br/>In this multidisciplinary project,...

Evaluation and improvement of remote sensing-based methods for river flow management

Rapid advancements in technologies open up possibilities for water resource authorities to increase their ability to accurately, safely and efficiently establish river flow observation through remote and non-intrusive observation methods. Low-cost Unmanned Aerial Vehicles (UAVS) in combination with Global Navigation Satellite Systems (GNSS) can...

Using River Geometry for Rating Curve Computation: A step towards Remote River Rating

Conventional practices of rating curve computation fall short in many aspects. They are data-intensive and are notoriously inaccurate in high-flow regimes as a result of extrapolation of low-flow curve fitting. By making use of a simple commercial UAV, a physically-based rating curve is computed that is substantiated by a detailed representation...

Balancing Costs and Benefits in Selecting New Information: Efficient Monitoring Using Deterministic Hydro-economic Models

Uncertainty reduces reliability and performance of water system operations. A decision-maker can take action, accepting the present uncertainty and facing its risks, or reduce uncertainty by first obtaining additional information. Information, however, comes at a cost. The decision-maker must therefore efficiently use his/her resources,...

Baseflow recession, Groundwater storage and rainfall runoff processes in Inselberg topography in Messica, Manica, Mozambique: Fieldwork Conveyance and FlexTopo withOCM

This master thesis investigated the origin of the seemingly perennial (base) flow in a hydrological complex, Inselberg (a type of mountain) dominated catchment in the Municipality of Messica, Manica Province, Mozambique. Smallholders rely on these perennial flows, since they have three growth seasons, two of them during the dry period. This year...
