This paper proposes a real-time control framework for the control of nationwide water systems, in particular in The Netherlands, consisting of numerous rivers, canals, reservoirs, and lakes. These water systems are of such a large scale that they cannot be controlled from a single location taking into account all locally available sensors, actuators, dynamics, and forecasts. Therefore, a framew...

Global warming-induced melting and thawing of the cryosphere are severely altering volume timing water supplied from High Mountain Asia, adversely affecting downstream food energy systems that relied on by billions people. The construction more reservoirs designed to regulate streamflow produce hydropower is a critical part strategies for adapting these changes. However, projects vulnerable com...

We investigated how watershed land use (a gradient of agricultural vs. forested land) relates to phytoplankton primary production (PPr) and photosynthetic parameters in 12 reservoirs in Ohio and examined spatial variation in these parameters. Shallow sites near stream inflows had higher light attenuation, total phosphorus (TP), chlorophyll, nonvolatile suspended solids (NVSS), light-saturated p...

Through a sequence of working questions, the following sections outline a global review of eutrophication of lakes and reservoirs with associated management challenges. A short state-ofthe art on remedial measures and feasible innovations to counterpart challenges enhances yardsticks of decentralization technologies, ecohydrology issues, suitable scenarios to societal goals, valuation of ecolog...

There is an increasing awareness among regional natural resource managers of the value of data collected by community groups. This includes monitoring of surface rivers, streams, lakes, reservoirs, wetlands, estuaries, coastal waters and groundwater. Water quality and condition data collected by community groups supplements information collected by state, regional and local resource management ...

The objective of this paper is to present a downsized prototype of an Autonomous Underwater Vehicle (AUV) designed with the idea of dealing with cooperative tasks involving multiple agents. The entire system has been designed for marine and underwater environmental surveillance and protection. The agents provide an interesting point in the surveillance of shallow coastal waters and shallow wate...

In the United States, many fish and wildlife species have been used nationwide to monitor environmental contaminant exposure and effects, including carcasses of the bald eagle (Haliaeetus leucocephalus), the only top avian predator regularly used in the past. Unfortunately, bald eagles are sensitive to investigator intrusion at the nest. Thus, the osprey (Pandion haliaetus) is evaluated as a po...

Inland waters (lakes, rivers and reservoirs) are now understood to contribute large amounts of methane (CH4) to the atmosphere. However, fluxes are poorly constrained and there is a need for improved knowledge on spatiotemporal variability and on ways of optimizing sampling efforts to yield representative emission estimates for different types of aquatic ecosystems. Low-latitude floodplain lake...

Climate-related declines in lake area have been identified across circumpolar regions and have been characterized by substantial spatial heterogeneity. An improved understanding of the mechanisms underlying lake area trends is necessary to predict where change is most likely to occur and to identify implications for high latitude reservoirs of carbon. Here, using a population of ca. 2300 lakes ...
