The water balance of a watershed is critical for the estimation budget to meet present and future domestic economic demand supply water. Water parameters like precipitation, temperature, evapotranspiration soil moisture content deficit surplus determine which further influenced by factors land use, types, seasonal variation other environmental factors. This paper intends estimate Barsachhu usin...

Overflow spillways are essential structures of dam projects, releasing surplus flood water to ensure safety. The discharge capacity these depends mainly on their geometry; the mos...

Phosphorus (P) surplus on dairy farms, especially confined operations, contributes to P buildup in soils with increased potential for P loss to waters. One approach to reduce P surplus and improve water quality is to optimize P feeding and improve P balance on farms. Here we report how varying P concentrations in lactating cow diets affects the amount as well as the chemical forms and fraction ...

An attractive feature of competitive markets is that they maximize the sum of consumer and producer surplus. Producer and consumer surplus are shown in the market supply and market demand diagram in Figure 7-4. Recall that the producer surplus for all producers is the area above the supply curve and below the market price line, and that the consumer surplus for all consumers is the area below t...

This study summarizes the changes (1991-2004) in plant distribution and cover in relation to soil factors in a salt marsh impacted by surplus of water from agricultural origin. An elevation of the groundwater level was observed, which led to a homogenization in the saline gradient. The changes were reflected in a shift in vegetation distribution which included the disappearance of most of the z...

When large capacity distributed generation including photovoltaic (PV) systems are installed in power systems, reverse power flow from PV systems may cause problem of surplus electric power. To reduce the reverse power flow without the reduction of PV power generation, energy management of customer equipment such as electric water heater is one of the solutions. Therefore, cooperative control o...
