Sustainable Management of Available Water Resources with Innovative Technologies - Management Of Highly Variable Water REsources in semi-arid Regions
February 2015 – June 2018
Jordan / West Bank
Karst groundwater is an important drinking water resource in the Jordanian highlands and the West Bank. Since the region is characterized by a steadily growing population groundwater is frequently endangered by contamination. For the local water suppliers, the monitoring of the raw water quality is imperative in order to be able to adapt the drinking water treatment accordingly. Within the SMART-MOVE project, a pilot study is being conducted to show how high-resolution online groundwater quality monitoring can optimize local drinking water management.
June 2015 - September 2018
The aim of the RiverView® project was to develop a holistic approach to better monitor and manage water bodies. For this purpose, an unmanned surface vehicle (USV) was developed which is capable of navigating small and medium-sized rivers both autonomously and via remote control. The USV forms an autonomously operating measuring catamaran. The systematic collection of synoptic visual, hydromorphological, hydrochemical and hydrophysical measuring technologies allows the simultaneous recording of georeferenced images, over- and underwater topography and the monitoring of water quality parameters. Between the two floats, a multi-parameter probe from SEBA Hydrometrie is attached to record water quality parameters such as temperature, oxygen concentrations, pH, electrical conductivity, redox potential and turbidity during the measurement run. The data obtained contribute significantly to a better process knowledge about water bodies and provide an improved basis for water monitoring and planning of measures in and on surface water.

Saltwater Intrusion and Morphodynamics in the Mekong Delta: Current Status, Upstream Impacts, and Future Developments
March 2017 - February 2019
The overall objective of the Catch-Mekong project is to provide innovative research and technologies for a sustainable and transboundary management of the natural water and land resources in the Mekong Delta. Process knowledge on the interaction between surface water and groundwater aquifers in coastal zones is of crucial importance in regions affected by rising sea water levels. Saltwater intrusion is a natural phenomenon in the coastal regions of the Mekong Delta, where seawater enters the delta's river and canal systems during the dry season due to the tidal influence. But if the salinity in the surface waters and groundwater is too high, the water can no longer be used for irrigation in agricultural production. To get a deeper understanding of the impacts of upstream developments and other external effects on saltwater intrusion in the Mekong Delta, two test sites were chosen for multiple water quality measurements in rivers, channels and shallow groundwater wells. Observation wells were specially equipped for high-resolution spatiotemporal salinity monitoring. In this process electric conductivity is monitored at multiple depths to identify the mechanisms of groundwater regeneration and exchange with the surface waters.
Integrated eco technologies and services for a sustainable Rual Rio de Janeiro
August 2013 - July 2017
The INTECRAL project is closely linked with the Rio Rural Project (PRR), a large-scale project to advance sustainable development in the Brazilian state of Rio de Janeiro. INTECRAL aims at driving research forward, at integrating technological knowledge into local agricultural production systems and at providing specific solutions for identified “bottlenecks”, which hinder the regional sustainable rural development. The specifically needed methods and technologies often are not available in Brazil, such as modern technologies for the sugarcane harvest for small-scale farmers, or they result in exorbitant costs, for example for water monitoring equipment. Measurement technologies for monitoring parameters such as electrical conductivity, oxygen concentration, turbidity, pH and nitrate are particularly suitable as decision-making support for water management or environmental authorities. In particular, online remote data transmission systems play a central role in order to be able to use, for example, event-controlled monitoring or multi-threshold alarms. SEBA Hydrometrie has equipped several groundwater and surface water quality stations with SEBA LogCom-2 and SEBA MPS-K16 devices in order to record the above-mentioned parameters in high-resolution and on-line. Several successful training courses were conducted with local research and government partners.
