Watershed hydrology analysis and management process and system with a network of weather stations and artificial drainage systems with artificial and natural reservoir management through locks and pumping stations. It evaluates potential hydrologic risk in each area and analyses the possible consequences of future precipitations using simulations. To make the simulation, it calculates hydrographs for each sub-basin, streams and rivers in the basin. It simulates the behavior of the basin under different scenarios corresponding to different types of management of the operation of locks and/or pumps and compares its results in terms of loss of flooded area, economic loss in each area, loss for flooding of urban areas, etc. Optimization of the simulation through artificial intelligence (AI, meta-heuristic algorithms, neural networks, etc.) allows it to act as a search engine to find better solutions and the best configuration of resource management that allows minimizing the socio-economic impact on each basin.

An operation for combining multiple video streams permits combining any number of overlay images and base images regardless of processes performed upon one or more of the images. Specifically, where the base images are dynamically sized and resized to provide a constant frame rate (despite varying frame complexity), the process similarly treats overlay images and even other base images. In the dynamic sizing process, a rendering time is compared to high and low water marks. During dynamic resizing, two double buffering operations and a synchronization operation are performed. After dynamic sizing and resizing, the resulting resized images are combined together, regardless of the frame rate of the individual images. Consequently, multiple video streams at varying frame rates are combined at a constant frame rate.

The detector strips are in electrical communication with a detection circuit and a control unit. The control unit uses the detection strips to monitor water level and uses such data to track filtered water consumption and to determine when the filter cartridge should be replaced.

One or more interface modules are provided as breaker circuits for receiving the generated signals, and a fluid control device is operable for limiting the water consumption.

In an alternate embodiment, a water monitoring system is designed to shut off the water supply to the water device and to shut off either the electrical supply or the gas supply to the heating unit of the water device in response to sensing a malfunction through one or more of a number of different sensed parameters.

A device which is neural networked with other such devices to control the irrigation of various irrigation zones. Each neural networked irrigation controller commences irrigation for its zone, provided sufficient water is available, either when a preselected period of time arrives or sensed zonal conditions so dictate. The determination of adequacy of water in the source forms the basis for neural networking. Each controller senses water level or pressure in the source and has its own initial water threshold value-a level or pressure at which irrigation will be permitted to commence. Optionally, each controller may have its own terminal water threshold value-a level or pressure which must be maintained in order for irrigation of the zone to continue. Thus, the controllers communicate hydraulically with one another. When a controller causes irrigation to commence, the water level or pressure in the source is lowered, and all controllers sense this and have their decisions affected accordingly; conversely, when a controller terminates irrigation, all controllers sense an increase in water level or pressure. If sufficient water is available in the source, irrigation of a zone will continue until either all zonal conditions have reached their specified terminal zonal threshold value or a specified period of time has passed. The start of irrigation may alternatively occur when a specified period of time has been reached.

When heating up the water in the lower inner part of a hot water tank by a heat pump unit, a control unit stops the heat-up operation while leaving the hot water in an amount corresponding to the residual water capacity in the hot water tank detected by water level thermistors. In the heat-up operation in the hot water tank, the residual hot water capacity in the tank is first detected, then the heat-up operation is stopped when the residual hot water reaches an amount corresponding to the detected residual hot water capacity. At this point, the hot water is stored so that the hot water newly heated up by the heat pump unit is laid above the residual hot water for the preceding day. Consequently, the reduction in the operating efficiency of the heat pump cycle is prevented without supplying the medium-temperature residual hot water to a condenser.
